Amino acid (Amino acid) as a molecular structure containing amino group (- NH2) and carboxyl (COOH) organic compounds. The formula is H2NRCOOH. Omega gamma delta beta alpha amino carbon atoms according to the connecting position in the carboxylic acid, can be divided into alpha, beta, gamma, Delta. Amino acids (C.C - C - C C - COOH).
Antibiotics (Antibiotic), also known as antibiotics, is a variety of organisms (plant, animal and microorganism, especially soil microbial metabolic activities) products, is also capable of selectively inhibiting the microorganisms in low concentration, virus and properties of tissue cells. The antibiotic has grown to more than 2000, but the actual application not much. The chemical structure of different antibiotics, character, according to their chemical structure can be divided into 32 categories, such as nucleosides, peptides, proteins, macrolide, polyene macrolides etc.
