Define Functions of Protein?
Each of the various proteins in the body serves a specific function in the maintenance of life. Any loss in body protein, in reality, means a loss in cellular function. In contrast to lipids and carbohydrates, proteins have no true body reserve. Humans when deprived of or insufficiently supplied with protein, compensate for this dietary deficiency by catabolizing some, but not all, of their tissue functionality. Cells, tissues, organs and whole systems cannot exist without proteins serving their various functions. So let us get to know the varied functions of proteins in our body.
