HUMAN NUTRITION

Detailed explanation-1: -Fatty acids are important building blocks of lipids and they give a diversity and chemical specificity to the complex lipids found in natural fats and oils, comparable to that given by the amino acids to proteins.

Detailed explanation-2: -Fats are actually a type of lipid. Lipids are a major class of biochemical compounds that includes oils as well as fats. Organisms use lipids to store energy and for many other uses. Lipid molecules consist mainly of repeating units called fatty acids.

Detailed explanation-3: -Fatty acids consist of a carboxylic acid (−OOH) group on one end of a carbon chain and a methyl group (−CH3) on the other end. Fatty acids can differ from one another in two important ways-carbon chain length and degree of saturation.
