What molecules combine to form a triglyceride?

What molecules combine to form 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 are the two main parts of a triglyceride?

The two main components of a triglyceride molecule are glycerol and fatty acids.

How do glycerol and fatty acids combine to form a triglyceride?

Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides. Triacylglycerols: Triacylglycerol is formed by the joining of three fatty acids to a glycerol backbone in a dehydration reaction. Three molecules of water are released in the process.

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.

What are the 2 compounds that combine to form complex lipids?

Triglycerides are classified as simple lipids because they are formed from just two types of compounds: glycerol and fatty acids. In contrast, complex lipids contain at least one additional component, for example, a phosphate group (phospholipids) or a carbohydrate moiety (glycolipids).

How are fatty acids and glycerol linked together?

In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.

How are triglyceride formed?

Triacylglycerols are formed by linking fatty acids with an ester linkage to three alcohol groups in glycerol. Triacylglycerols are the form in which fat energy is stored in adipose tissue. Triacylglycerols are sometimes referred to as triglycerides.

What is the bond linkage formed when triglycerides are formed?

A triglyceride consists of glycerol and fatty acids which are held together by ester linkages.

What are the two components of a triglyceride?

The 2 components of Triglyceride structure – Glycerol and Fatty Acids. Triglyceride Structure Figure shows how 3 Fatty Acids combine with Glycerol to form Triglyceride Home

How are fatty acids broken down in a triglyceride molecule?

As shown in above triglyceride structure figure, the three fatty acids are attached to each OH group, and bonds between each fatty acid and glycerol are ester bonds. The molecule is broken down by the action of an enzyme called “pancreatic lipase”.

How are triglycerides different from liquid fats?

Triglycerides are the main constituents of animals and vegetable fats and have low density than water thus float on water. At normal temperatures these fats are solid called “fats”, whereas in liquid form they are called “oils”.

How are triglycerides broken down in vegetable oil?

Triglyceride. Vegetable oils can be hardened by treatment with hydrogen under pressure. In alkali, triglycerides are broken down (saponified) to form glycerol and three molecules of soap (salts of the fatty acids).
