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 is made up of smaller building blocks called amino acids. A number of different enzymes are needed to process these amino acids for use by the body. Because of missing or non-working enzymes, people with amino acid disorders cannot process certain amino acids.These amino acids, along with other toxic substances, then build up in the body and cause problems. number of different enzymes are needed to process these amino acids for use by the body.
