Detailed explanation-1: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.
Detailed explanation-2: -Both animal and plant proteins are made up of about 20 common amino acids. The proportion of these amino acids varies as a characteristic of a given protein, but all food proteins-with the exception of gelatin-contain some of each. Amino nitrogen accounts for approximately 16% of the weight of proteins.
Detailed explanation-3: -A food is considered a complete protein when it contains all nine essential amino acids that our body can’t produce on its own. By comparison, incomplete proteins contain some, but not all, of the essential amino acids, and in various amounts.
