Abstract

A method for the quantitative determination of lysine, histidine and tyrosine in foods based on pre-column derivatization with 5-dimethylaminonaphthalene-1-sulfonyl chloride (DnsCl) and reversed-phase liquid chromatography has been developed. Derivatization conditions, including DnsCl concentration, time, temperature, and buffer solution were studied. To establish the reliability of the proposed liquid chromatographic (LC) method, the precision and accuracy of the analyses were evaluated using samples of casein and lysozyme.

Bacterial Cell Wall Structure (ASM)

Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Here is the latest research on bacterial cell wall structures.
