application
Ornithine adds food nutrition enhancer to food, which can not only supplement the nutritional defects of natural food, but also improve the nutritional content and proportion in food to meet people's nutritional needs. In addition, the use of food nutrition fortifiers can be specially supplemented with certain nutrients to achieve the purpose of special diet and health.
physiological function
Ornithine is a basic amino acid. Although it cannot be found in ordinary proteins (not belonging to the 20 amino acids that make up the protein), it exists in antibacterial peptides such as brevis casesin and brevis. In addition, & delta;-N-acetylornithine. It is produced by the decomposition of arginine as alkali or arginase. As a part of the urea cycle, it is related to urea generation. Aminoyl phosphoric acid is combined with ornithine to form citrulline and phosphoric acid. Citrulline is converted into arginine, and arginine is cleaved into urea and ornithine. It plays an important role in metabolism. In the organism, it can transform with arginine, glutamic acid, and proline, and can undergo amino transfer with α-keto acid and glyoxylic acid, and decarboxylate under the action of ornithine dehydroxylase to generate butylene Diamine can be further synthesized to polyamines.
