Our current examination of proteins and amino acids will cover the metabolism of the protein we eat, dietary protein, and catabolic situations in the body. A general understanding of the molecular structure of proteins and amino acids is needed to understand their metabolism. The Structure Of Proteins & Amino Acids.
