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.
Any amino acids that are left over after synthesis are either stored as fat or converted into energy. Amino acids can be classified as essential and non-essential. Essential amino acids cannot be made by the body but are essential to protein metabolism.These amino acids must be acquired from food. Non-essential amino acids are required for normal cell functioning and can be synthesized from other amino acids in the body.thletes may supplement their diets with protein sources such as egg white powder, whey, casein or soy. Consuming too much protein places unnecessary strain on the body. Both meat and soy proteins contain all the essential amino acids that the body requires each day.
