HUMAN NUTRITION

Detailed explanation-1: -Generally, a fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end. It is that carboxyl group that makes it an acid (carboxylic acid).

Detailed explanation-2: -Fatty acids have a long chain of hydrocarbons with a carboxyl group attached and may have 4-36 carbons; however, most of them have 12-18. 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.

Detailed explanation-3: -Fatty acids are long-chain carboxylic acids that may contain one or more carbon–carbon double bonds. C) they contain; or (3) the position of these double bonds. As the length of the fatty acid increases, the melting point of the fatty acid increases (Table 1).

Detailed explanation-4: -Fatty acids are made up of a long chain of hydrocarbons with a carboxyl group attached.
