Unit 3 - Proteins and Amino acids
3.1.Introduction
Proteins are among the most important constituents of all living cells and represent the largest chemical group in the animal body, with the exception of water; the whole fish carcass contains on an average 75% water, 16% protein, 6% lipid and 3% ash. Proteins are essential components of both the cell nucleus and cell protoplasm, and accordingly account for the bulk of the muscle tissues, internal organs, brain, nerves and skin.
