功能补充剂中有效成分检测方案(氨基酸分析仪)

Analysis of B-Alanine， Glucosamine and Galactosamine (L-8900) L-8900 Amino Acid Analyzer with the eluent for the special amino acid analysis， is shown. B-alanine is a structural isomer of alanine contained in protein. It is a free amino acid mainly found in muscle. The acetyl forms of glucosamine and galactosamine widely exist in biological sphere as the constituents of chitin of crustacean and insects， proteoglycans such as hyalron acid， and glycans on cell surfaces. Acetyll glucosamine and acetyl galactosamine mostly exist in the forms of glycans and areanalyzed by an amino acid analyzer after hydrolyzed to glucosamine and galactosamine. These amino acids are also used as the supplements for the improvement of athletic ability and prevention and improvement of arthritis. SAMPLE 20 uL of Std. Soln.
