Amino esters are organic compounds formed by the reaction of an amino acid and an alcohol. They contain both an amino group (-NH2) and an ester group (-COO-), which gives them unique properties. These compounds are often used in the synthesis of pharmaceuticals and agrochemicals due to their ability to participate in various chemical reactions. In addition to their industrial applications, amino esters can also be found in biological systems. They play a role in the metabolism of proteins and can be involved in neurotransmission. Their diverse functions make them important in both chemistry and biology.
