Riboflavin (Vitamin B 2)

Riboflavin, also known as vitamin B 2, is a component of the flavin coenzymes, FAD and FMN (Figure 14.7). It is composed of an isoalloxazine ring system linked to ribitol. The ability of the ring system of riboflavin to exist as a semiquinone allows the flavin coenzymes to accept electrons either singly or in pairs.
