What are triglycerides classified by?

Triglycerides belong to “glycerides”, a group of esters formed from glycerol reacting with fatty acids. They are classified based on the number of fatty acids reacting with glycerol. Thus, a triglyceride would have three fatty acids reacting the hydroxyl functional group of the glycerol.

Are triglycerides considered lipids?

Triglycerides are a type of fat (lipid) found in your blood. When you eat, your body converts any calories it doesn’t need to use right away into triglycerides. The triglycerides are stored in your fat cells. Later, hormones release triglycerides for energy between meals.

What nutrient class is triglycerides?

Lipids — the fat family including, triglycerides (fats and oils), phospholipids (lecithin), and sterols (cholesterol). Fats–lipids that are solid at room temperature. Oils–lipids that are liquid at room temperature. Triglycerides–the major class of dietary lipids.

Is a triglyceride a saturated or unsaturated fat?

Fats may be either saturated or unsaturated. A saturated fat is a fat that consists of triglycerides whose carbon chains consist entirely of carbon-carbon single bonds.

Which class of organic compound is classified in triglycerides?

The triesters of fatty acids with glycerol (1,2,3-trihydroxypropane) compose the class of lipids known as fats and oils. These triglycerides (or triacylglycerols) are found in both plants and animals, and compose one of the major food groups of our diet.

What are the 4 types of triglycerides?

The three types of fatty acids that compose triglycerides are saturated, monounsaturated and polyunsaturated fatty acids. From these three types of fatty acids come the three types of triglycerides, or fats, saturated, monounsaturated and polyunsaturated triglycerides.

What are examples of triglycerides?

Triglycerides are fats from the food we eat that are carried in the blood. Most of the fats we eat, including butter, margarines, and oils, are in triglyceride form. Excess calories, alcohol or sugar in the body turn into triglycerides and are stored in fat cells throughout the body.

What are the 7 main groups of triglycerides?


  • Saturated fat.
  • Unsaturated fat. Monounsaturated fat. ω−7. ω−9. Polyunsaturated fat. ω−3. ω−6. Trans fat. Interesterified fat.

What are the 3 classifications of lipids?

The three main types of lipids are triacylglycerols (also known as triglycerides), phospholipids, and sterols.

  • 1) Triglycerides make up more than 95 percent of lipids in the diet and are commonly found in fried foods, butter, milk, cheese, and some meats. …
  • 2) Phospholipids make up only about 2 percent of dietary lipids.

Is triglyceride to glycerol anabolic or catabolic?

The answer is b) anabolic reaction. A triglyceride is a lipid molecule constructed from glycerol and fatty acids, specifically, three fatty acid…

Can triglycerides be saturated and unsaturated?

Triglycerides are lipid compounds composed of a glycerol esterified to 3 fatty acid chains of varying length and composition. These fatty acid chains can be saturated or unsaturated, and the chemical composition of each chain is different.

Do triglycerides affect LDL?

When you have high triglyceride levels, there’s a good chance you also have low levels of HDL “good” cholesterol and high levels of LDL “bad” cholesterol. This combination raises the chance that you’ll have a heart attack or stroke.

Which functional group is common in triglycerides?

It has a glycerol backbone with three fatty acids linked by an ester, so the functional group is Ester.

Why triglycerides are called neutral lipids?

Neutral fats, in particular, are fats that are described as neutral because they are uncharged and do not contain acidic or basic groups. They are nonpolar and hydrophobic.

What is the composition of triglycerides?

A triglyceride is composed of glycerol and three fatty acids. When all of the fatty acids in a triglyceride are identical, it is termed a “simple” triglyceride. The more common forms, however, are the “mixed” triglycerides in which two or three kinds of fatty acids are present in the molecule.

How does a triglyceride differ from a carbohydrate?

Carbohydrates share the C, H, and O composition as lipids, but they differ in structure. Lipids are generally exist as triglycerides, which consist of a triple hydroxyl alcohol (glycerol) that has bonded to three long-chain carboxylic acids (fatty acids) in a triple condensation reaction.

What are 2 types of triglycerides?

Triglyceride. TG is an ester derived from glycerol and fatty acids. There are two different types of TG: saturated and unsaturated (Pundir and Narang, 2013).

Which is more important LDL or triglycerides?

Remember the triglyceride to HDL ratio is the stronger predictor of heart disease, much more so than “just” high cholesterol and LDL/HDL ratios. It is important to understand there are other predictors and not just “high” cholesterol that indicate a potential problem.

What are 3 functions of triglycerides?

What Is the Function of Triglycerides?

  • Characteristics. Triglycerides are the most common lipid found in the body. …
  • Energy Storage. Triglycerides provide your body with energy, but their main function is to store energy for later use. …
  • Health Impact. …
  • Healthy Levels. …
  • Lifestyle Changes.

What is a healthy triglyceride level by age?

The ranges for children and teenagers ages 10–19 are slightly higher: Normal: under 90 mg/dl. Borderline high: 90–129 mg/dl. High: over 130 mg/dl.

Do carbohydrates turn into triglycerides?

When you eat extra calories — especially carbohydrates — your liver increases the production of triglycerides. When you consume — or your body creates — excess triglycerides, they’re stored in fat cells for later use.

What food lowers triglycerides?

Foods that can help lower triglycerides

all vegetables, especially leafy greens, green beans, and butternut squash. all fruits, especially citrus fruits, and berries. low fat or fat-free dairy products, such as cheese, yogurt, and milk. high-fiber whole grains, such as quinoa, barley, and brown rice.

What are 4 types of lipids?

The four main groups of lipids include:

  • Fatty acids (saturated and unsaturated)
  • Glycerides (glycerol-containing lipids)
  • Nonglyceride lipids (sphingolipids, steroids, waxes)
  • Complex lipids (lipoproteins, glycolipids)

What is another name for triglycerides?

Triglycerides (TGs, also called neutral fats, triacylglycerols, or triacylglycerides) are a common, simple type of lipid consisting of three long-chain fatty acids esterified to glycerol [126].

What are examples of phospholipids?

The most common phospholipids are phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidylserine. These phospholipids share the common features of fatty acids esterified to the 1 and 2 positions of the glycerol backbone with the phosphate group esterified to the 3 position (Figure 2).

How do phospholipids and triglycerides differ?

The main difference between the structures of phospholipid and triglycerides is that a phospholipid molecule is composed of a glycerol backbone attached to two fatty acids and a phosphate group whereas triglyceride is composed of three fatty acid groups.

What is the difference between a phospholipid and a triglyceride?

Phospholipids are similar to triglycerides, but they do vary slightly in form and function. While triglycerides have glycerol and three fatty acids, phospholipids have glycerol, two fatty acids and a phosphate. … Instead, phospholipids help break down fats during the digestive process.

How do triglycerides phospholipids and sterols differ in composition and structure?

Triglycerides are also known as triacylglycerols and compose 95% of fat in the foods we eat. … Phospholipids bring water and fat together and are called emulsifiers. Phospholipids make up cell membranes and lipid carrier molecules. Sterols are found in tissues of animals and plants.

What happens to the glycerol produced when triglycerides are metabolized?

Lipolysis. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl CoA, which is used by the Krebs cycle …

What is the fate of glycerol in triglyceride catabolism?

The Fate of Glycerol and Fatty Acids

Once a triglyceride is completely broken down, the free fatty acids bind to serum albumin in the blood stream and carries the free fatty acids to the tissues that need energy. Glycerol is absorbed by the liver.

What type of a reaction is a triglyceride to glycerol 3 fatty acids?

They play an important metabolic role, serving as efficient energy-storage molecules that can provide more than double the caloric content of both carbohydrates and proteins. Figure 1. Triglycerides are composed of a glycerol molecule attached to three fatty acids by a dehydration synthesis reaction.

What is the difference between saturated and unsaturated triglycerides?

The key difference between saturated and unsaturated triglycerides is that saturated triglycerides have only single bonds between carbon atoms, whereas unsaturated triglycerides have double or triple bonds between carbon atoms.

What type of macromolecule is a triglyceride?

In Summary: Lipids

Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides.

Does olive oil cause high triglycerides?

Increase your intake of unsaturated fats

A 2019 review of 27 studies reported that while olive oil consumption does decrease triglycerides levels, it does so significantly less than other types of plant oil ( 30 ).

Which is worse high cholesterol or triglycerides?

In fact, high triglycerides are as dangerous as bad cholesterol when it comes to your risk for heart disease. According to researchers at the Centers for Disease Control and Prevention (CDC), high triglycerides could be a problem for one-third of all Americans.

What is the main cause of high triglycerides?

Cause. The most common causes of high triglycerides are obesity and poorly controlled diabetes. If you are overweight and are not active, you may have high triglycerides, especially if you eat a lot of carbohydrate or sugary foods or drink a lot of alcohol.

What is the structure and function of triglycerides?

Triglycerides consist of a glycerol “backbone” along with three fatty acids bonded to the backbone in an ester linkage. Glycerol is a three-carbon molecule, C(H2)OH-C(H)OH-C(H2)OH. When one of its hydroxyl groups (-OH) loses a hydrogen, a fatty acid can bind to the oxygen in its place, creating a C-O-C (ester) bond.

What functional group is present in both waxes and triglycerides?

Lipids are biomolecules that are soluble in organic non-polar solvents and are hence insoluble in water. Glycerides and waxes form a sub-group, which have an ester as the major functional group and include triglycerides and phospholipids.

What functional group is present in all triglycerides Mcq?

The functional group present in triacylglycerol is ester. Triacylglycerol is a triester of glycerol with higher fatty acids.

What is the difference between triglycerides and triacylglycerols?

The main difference between triacylglycerol and triglyceride is that triacylglycerol is the correct chemical name for an ester derived from glycerol bound to three fatty acids whereas triglyceride is the common name for the substance. Triglycerides are the main constituent of the animal and vegetable fats in the diet.

Is triglyceride a lipid?

Triglycerides are a type of fat (lipid) found in your blood. When you eat, your body converts any calories it doesn’t need to use right away into triglycerides. The triglycerides are stored in your fat cells.

What is the triglyceride backbone?

Definition. A triglyceride (TG) molecule consists of a glycerol backbone esterified with three fatty acids. Triglycerides are the main constituent of vegetable and animal fats in the diet, and are the main constituent of the body’s fat stores.
