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.
A: Amino acids are the building blocks that make up protein. Your body puts them together like Legos to create muscle. While your body can make some from scratch (called non-essential amino acids), you have to obtain others (essential amino acids), from food or supplements. These essential amino acidsâespecially a certain kind called branched-chain amino acids (BCAAs)âare the limiting factor in your bodyâs ability to build muscle.
