  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.
