1. Lysine is an amino-acid. It isan essential amino-acid for animals. Lysine is not synthesized in animals, hence it must be ingested as lysine-containing proteins. 2. The effect of lysine is: (1)meeting the requirements of animals and improving growth. (2)improving amino acids'balance. (3)increasing utilization of feed resources, decrease the cost of feed. (4)increase the nutritive values of plant protein. (5)benefit the resources of protein feed as a whole. Product Description L-Lysine Synonyms: (S)-2,6-DIAMINOCAPROIC ACID;(S)-(+)-LYSINE;LYSINE;LYSINE, L-(+)-;L-(+)-LYSINE;L-LYSINE;L-LYSINE BASE;H-LYS-OH CAS: 56-87-1 MF: C6H14N2O2 MW: 146.19 EINECS: 200-294-2 Chemical Properties White to pale yellow crystalline powder Usage Essential amino acid for human development. Lysine residues are useful in many cellular processes, due to their ability to accept a wide variety of post-translational modifications. L-Lysine, one of essential amino acids, is the first limiting amino acid for pigs and the second for poultry. The level of dietary L-Lysine concentration significantly influences on the growth performance and feed efficiency. Supplementing L-Lysine in dietary could balance the amino acid profile in the formula and fulfill the requirements of animals to optimize the technico-economic result of production.
