Application

Pyridoxal hydrochloride has been used as a calibrant for liquid chromatography of food samples. It has also been used as a component of arginine decarboxylase broth and lysine decarboxylase broth (LDB) for culturing lactic acid bacteria (LAB) and food-borne pathogens (FBP), respectively.
For the labeling of amino acids and their detection in picomolar amounts; Coenzymes and Cofactors, vol. 1: Vitamin B6, Pyridoxal Phosphate

Biochem/physiol Actions

Pyridoxal hydrochloride interacts with cysteine of cathepsins and inhibits their activity. It elicits protective function in cornu Ammonis (CA) 1 neurons during ischemia.
