Proteins in the Body by Laura Proteins in the Body by Laura Proteins are essential for growth and repair of body tissues, of the utmost importance in body functioning. Proteins also help your strength and power of being able to use your legs, arms, and other parts of your body. Most of the protein in your body comes from the food you eat. Protein also comes from other things like, working out, or just eating right.
Proteins are sometimes coats of a virus.
A protein coat protects the D.N.A in a person's body. It also helps protect the R.N.A in a person's body too. These protein-producing areas, in the ribosomes, are one form of an R.N.A coat. Proteins themselves are long chains of amino acids hooked together by peptide bonds in which the 20-odd basic amino acids are repeated several times and arranged in different orders. Even the smallest protein is a chain of 124 amino acids.
