L-lysine hydrochloride is used as feed nutrition enhancer and is an essential component of livestock and poultry nutrition

Description

Lysine, the chemical name is a, ε-diaminocaproic acid or 2,6-diaminocaproic acid, is a basic amino acid, composed of 1 carboxyl group and 2 amino groups, its molecular formula is C6H14N2O2, and its relative molecular mass is 146.19 . There are two isomers of lysine, which are divided into L form and D form, but only the L form is active. L-Lysine is generally crystalline powder or white crystal, with a melting point of 224.5 °C, but it will turn black at 210 °C. It is optically active, easily absorbs CO2, insoluble in ether, hardly soluble in ethanol, and easily soluble in water.

Applications

Amino acids are not only important substrates for the synthesis of proteins and other nitrogen-containing compounds, but also key regulators of major metabolic pathways in animals. Not every amino acid needs to be provided by feed. Only essential amino acids, that is, those amino acids that cannot be synthesized in the animal body to meet the body's needs, or even cannot be synthesized in the body, need to be provided by feed. Among them, during the growth of pigs, lysine (Lys) is the first limiting amino acid, and adding it to the diet can make it play an important role in protein synthesis and metabolism. For example, lysine can be directly absorbed by the intestine to synthesize proteins, and can also regulate other metabolic processes such as antiviral activity, NO synthesis, protein methylation, ubiquitination, acetylation, and glycosylation. In the "ideal amino acid" mode, the addition ratio of each amino acid is based on lysine, that is to say, the level of lysine in the pig diet can ensure sufficient supply of other amino acids, otherwise it may lead to The oversupply of medium and crude protein leads to the excretion of excess nitrogen into the environment, which has an impact on the environment, etc. Therefore, lysine has attracted much attention in the field of pig production research because of its important nutritional and physiological roles.
