Itâs not a major part of any starvation response. Once proteins are degraded, the amino acids may be used in anabolism to make new proteins, or may be catabolized to produce energy. Amino acid catabolism produces ammonia (NH3) and the carbon skeleton. Ammonia is toxic and has to be managed by the urea cycle.
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.
