Vitamin B6 Complex -- Microbiological Method

VIEW METHOD

Objective
The vitamin B6 group consists of pyridoxine, pyridoxal, pyridoxamine, and one or more unidentified labile factors. All members of the complex show comparable activity for Saccharomyces uvarum (American Type Culture Collection [ATCC] No. 9080) and the rat. Hence this procedure measures the biological vitamin B6 activity rather than the concentration of pyridoxine or any single derivative.
