L-Lysine hydrochloride Powder Usage and Synthesis.

L-Lysine is one of the 8 essential amino acids in human body, which can promote human development, enhance immune function, and improve the function of central nervous tissue. It is used as a cerebral protective agent for the treatment of craniocerebral trauma, chronic cerebral tissue ischaemia and hypoxic diseases.

Uses and functions of L-Lysine hydrochloride.

Amino acid drugs, which can promote the growth and development of children, improve appetite and gastric acid secretion, and are used for the recovery of children after illness and during pregnancy and lactation. There are also lysine derivatives and compound preparations, all of which are amino acid drugs.

Such as L-lysine acetate, injectable lysine pirelline, lysine tablets, lysine chewable tablets, lysine dry syrup (for children), lysine-B12 chewable tablets (for children), lysine-B12 granules (for children), lysine-B12 combination and so on.

Adverse reactions: no obvious toxic side effects. However, it should be used with caution in cases of hyperchlorhydria, acidosis and renal insufficiency.

Characteristic of L-Lysine hydrochloride.

White crystal or crystalline powder, odourless, sweet taste, because lysine pure product is easy to absorb moisture agglomeration, in order to facilitate the separation and purification and application, it is often made into hydrochloride.

Usually more stable (relative humidity below 60%), relative humidity above 60% and moisture-absorbing lumps, resulting in dihydrate. Easily soluble in water (40%, 35 ° C), a few insoluble in ethanol and ether, and reducing sugar such as glucose is decomposed by co-heating, resulting in appetising bread aroma. mp263-264 ° C, isoelectric point 10.56, [α]25D +13.5 ° (H2O), [α]25D +26.0 (5mol / LHCl).

Lysine is one of the essential amino acids. Nutritionists classify it as the "first deficient amino acid". It plays an important role in maintaining the ammonia balance of human body.

If the human body lacks lysine, it will cause protein metabolism disorder, in the development of children, recovery from diseases and pregnancy and lactation, the nutritional requirements for lysine are higher.

Product Methods of Bulk L-Lysine hydrochloride Powder.

The industrial production of lysine is still mainly by direct microbial fermentation. Lysine is an amino acid of the aspartic acid branching system, and aspartic acid kinase is the key enzyme, which is inhibited by coordinated feedback inhibition from lysine and threonine, and a single amino acid cannot completely inhibit the enzyme activity.

The strain used, almost always Corynebacterium glutamicum, is a hyperserine nutrient-deficient variant that lacks hyperserine dehydrogenase.

Since aspartate kinase is not inhibited by a single amino acid, the high serine-deficient variant strain restricts the production of threonine and lifts its feedback inhibition, so lysine fermentation is carried out, and the production strains can have a sugar yield of more than 40%. Microbiology Research Institute of Chinese Academy of Sciences, high serine-deficient strain A.S.1.563, the pilot acid production rate of up to 3.66%, the sugar yield of 30%, with sugar cane molasses can be as high as 42%.
