Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central ...

Cyanophycin is a natural biopolymer produced by a wide range of bacteria, consisting of a chain of poly-l-Asp residues with l-Arg residues attached to the β-carboxylate sidechains by isopeptide bonds. Cyanophycin is synthesized from ATP, aspartic acid a
An a-mean-oh acid. Amino acids are awesome! They have a huge role in the function of our bodies. They function both as building blocks for proteins, and they function as intermediates in metabolic reactions. There are 20 different types of amino acids found in proteins, which means that ...
In chemistry, an amino group -NH2 is represented as + –Carboxyl group or acid group represented by -COOH at the beginning. Amino acids are linked together by peptide bonds forming long chains of tens or hundreds of amino acids (proteins). The peptide bond takes place between a carbon atom...
