Octopine
Octopine is a derivative of the amino acids arginine and alanine. It was the first member of the class of chemical compounds known as opines to be discovered. Octopine gets its name from '' Octopus octopodia'' from which it was first isolated in 1927. Octopine has been isolated from the muscle tissue of invertebrates such as octopus, '' Pecten maximus'' and '' Sipunculus nudus'' where it functions as an analog of lactic acid. Plants may also produce this compound after infection by '' Agrobacterium tumefaciens'' and transfer of the octopine synthesis gene from the bacterium to the plant. Octopine is formed by reductive condensation of pyruvic acid Pyruvic acid (CH3COCOOH) is the simplest of the keto acids, alpha-keto acids, with a carboxylic acid and a ketone functional group. Pyruvate, the conjugate acid, conjugate base, CH3COCOO−, is an metabolic intermediate, intermediate in several m ... and arginine through the action of the NADH-dependent enzyme octopine de ...
