CAS:61-90-5 | L-Leucine

Products Description

L-Leucine, also known as H-Leu-OH, is one of the eight essential amino acids for the human body. It is classified as an aliphatic amino acid among the twenty proteinogenic amino acids. Its chemical formula is C₆H₁₃NO₂, the CAS number is 61-90-5, and its relative molecular weight is 131.175 g/mol.

In terms of physical and chemical properties, L-Leucine appears as white, shiny hexahedral crystals or a white crystalline powder at room temperature. It is odorless with a slightly bitter taste. It is slightly soluble in ethanol, soluble in dilute hydrochloric acid, alkaline hydroxide, and carbonate solutions, but insoluble in ether.

Basic Info

Production method

Regarding production methods, the extraction method involves hydrolyzing proteins with a high L-Leucine content under acidic conditions to obtain a mixture of amino acids, followed by separation, purification, and refinement to isolate the product. The chemical synthesis method produces racemic DL-Leucine, which is then separated into optical isomers. The enzymatic catalysis method uses transaminase to convert α-ketoisocaproic acid into L-Leucine. The microbial fermentation method employs specific strains to produce L-Leucine.

Uses

In the food industry, L-Leucine is used as a nutritional supplement, commonly in bread and noodle products. It can serve as a flavoring agent to enhance food taste and is also used in the preparation of amino acid infusions and comprehensive amino acid preparations.

In the medical field, L-Leucine is used for glucose metabolism disorders, liver diseases with reduced bile secretion, anemia, poisoning, muscular atrophy, sequelae of poliomyelitis, neuritis, and mental illnesses. It can also function as a hypoglycemic agent and a plant growth promoter.
