SUMMARY Proteins are the building blocks of life.
Proteins are used for tissue repair and maintenance. Amino acids are small units that combine to form a protein molecule. Aminoacids are classified as essential, semiessential and non essential aminoacids. Proteins are classified as simple proteins, conjugated or complex proteins and derived proteins.
Proteins are also classified as complete proteins and incomplete proteins. If two sources of incomplete proteins are combined in the same meal, the resulting protein may be of better quality. These are called as Complementary proteins. Animal sources are complete proteins which includes meat, egg, fish and poultry and they are good protein foods in both quantity and quality.
Milk is a valuable source of protein because although it does not contain a large quantity of protein, the quality is excellent. Good sources of plant proteins are legumes, pulses, nuts and oil seeds, but their quality is poorer than that of animal foods. All vegetables and fruits are a poor source of protein. The main functions of protein are building and repair of body tissues and regulation of body processes.
