Biosynthesis of vitamin B6: incorporation of three-carbon units.
Pyridoxol, one of the forms of vitamin B(6), is derived from three glycerol units. One of these is incorporated by way of pyruvate as a two-carbon fragment at the oxidation level of acetaldehyde. The other two glycerol units are incorporated intact, possibly by way of triose phosphate.
