Browsing: Amino Acid

An amino acid is an organic compound that serves as the building block for proteins and plays a crucial role in various biological processes. Each amino acid consists of a central carbon atom (alpha carbon), an amino group, a carboxyl group, a hydrogen atom, and a variable side chain or R group that determines the specific characteristics and functions of the amino acid. There are twenty standard amino acids encoded by the genetic code, each differing in their side chain properties, which influence the structure and function of proteins. Amino acids participate in the synthesis of proteins by linking together in a specific sequence through peptide bonds, forming polypeptides, which then fold into functional proteins. They are also involved in other critical roles such as neurotransmitter transport and biosynthesis of other biomolecules.
