Description

Lysinoalanine CAS NO 18810-04-3 is a naturally occurring, cross-linked amino acid derivative formed from lysine and dehydroalanine residues. This compound is of significant interest in biochemical research and the food science industry due to its role as a marker for protein processing and nutritional quality. It is primarily utilized by researchers studying protein chemistry, food safety, and nutritional biochemistry, as well as by quality control laboratories in the food and feed sectors.

Application

• Biochemical Research: Used as a standard or reagent in studies investigating protein cross-linking, Maillard reaction products, and advanced glycation end-products (AGEs).
• Food Science & Safety: Acts as a critical marker for monitoring the extent of alkali processing in foods (e.g., protein isolates, texturized vegetable proteins) and assessing potential nutritional quality loss.
• Analytical Reference Standard: Serves as a high-purity certified reference material (CRM) for the accurate quantification of lysinoalanine in complex matrices using HPLC, LC-MS, or amino acid analysis.
• Nutritional Studies: Employed in research to understand the bioavailability and metabolic fate of modified amino acids in animal and human nutrition.
• Feed Industry Analysis: Used in quality control protocols to evaluate the processing conditions of protein-rich animal feed ingredients.
