Triglycerides are a type of fat found in the blood. They are the most common type of fat in the body. Most of the fats we eat, such as natural oils — both polyunsaturated and monounsaturated — animal fats and trans fats, are triglycerides.

What are also known as 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 .
What type of biological molecule is a triglyceride?
Triglycerides are esters in which three molecules of one or more different fatty acids are linked to the alcohol glycerol; they are named according to the fatty acid components; e.g., tristearin contains three molecules of stearic acid, and oleodistearin, one of oleic acid and two of stearic acid.
What is another name for triglyceride synthesis?
Lipogenesis encompasses both fatty acid and triglyceride synthesis, with the latter being the process by which fatty acids are esterified to glycerol before being packaged into very-low-density lipoprotein (VLDL).
What are the chemical and biochemical properties of triglycerides?
They are non-polar, hydrophobic, insoluble in water and soluble in organic solvents. Specific gravity is less than water. Therefore fats and oil float on water. The saturated fatty acids have higher melting points than unsaturated fatty acids of corresponding length.
Why fats are also known as triglycerides?
Triglycerides: The major form of fat stored by the body. The word “triglyceride” reflects the fact that a triglyceride consists of three (“tri-“) molecules of fatty acid combined with a molecule of the alcohol glycerol (“-glyceride”) that serves as the backbone in many types of lipids (fats).
What is the chemical structure of triglycerides?
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.
Is glycerol a triglyceride?
Triglycerides are composed of a glycerol molecule bound to three fatty acids and are digested by pancreatic lipase. Triglycerides are a major component of very-low-density lipoprotein (VLDL) and serve as a source of energy.
What is a triglyceride an example of?
Triglycerides and cholesterol are both fatty substances known as lipids. But, triglycerides are fats; cholesterol is not. Cholesterol is a waxy, odorless substance made by the liver that is an essential part of cell walls and nerves.
What 4 molecules make up a triglyceride?
Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid molecules. Alcohols have a hydroxyl (HO–) group. Organic acids have a carboxyl (–COOH) group. Alcohols and organic acids join to form esters.
Are triglycerides polymers?
Fatty acids form more complex lipid polymers called triglycerides, triacylglycerols or triacylglycerides when each single-bonded oxygen molecule bonds to a carbon that’s part of a glycerol molecule. Triglycerides are also commonly found in foods, especially animal products.
What means triglyceride?
What are triglycerides? 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 is the biochemical function of triacylglycerols?
Functions Triacylglycerols are stored as fat droplets in large amounts in vertebrate fat cells, and in plants as oils in the seeds. Triacylglycerol is a better stored energy source than polysaccharides because oxidation of triacylglycerols produces more than twice as much energy than the oxidation of carbohydrates.
