Proteins: Definition, Functions, Types And Characteristics-- &#; Proteins are essential to fulfill various functions of the body , such as the formation or repair of muscles , bones and other tissues. They also intervene in cell division and in the defense of the organism. Low levels of protein in the body can cause diseases such as anemia, especially in the stages of pregnancy or early childhood.

Physiology, Proteins - PubMed-- &#; Proteins serve as structural support, biochemical catalysts, hormones, enzymes, building blocks, and initiators of cellular death. Proteins can be further defined by their four structural levels: primary, secondary, tertiary, and quaternary. The first level is the primary structure because it is the most basic level of protein structure.
