biotin \bi"o*tin\ n.
a B vitamin ({C10H16N2O3S}) that aids in body growth; --
called also {vitamin H} and {coenzyme R}. It functions as a
coenzyme in many carboxylation reactions.

Note: Biotin binds tightly to the substance avidin, found in
raw egg-whites. Rats or chick on a diet high in raw
egg-white may develop skin lesions and retarded growth,
which can be prevented by adding biotin to the diet.
