Biological roles: 1. Amino acids can be metabolized to produce energy. This is especially. important during fasting, when the breakdown of muscle protein is a major. source of energy and biosynthetic precursors. 2. Some amino acids act as neurotransmitters, and some act as starting.
Protein occurs in all living cells and has both functional and structural properties. Amino acids, assembled in long chains, are the building blocks of protein. Of the 20 amino acids found in proteins, some can be made by the body while others are essential in the diet.Amino acids are used for the synthesis of body proteins and other metabolites and can also be used as a source of dietary energy.f the 20 amino acids found in proteins, some can be made by the body while others are essential in the diet.
