An examination of the molecular architecture of biotin, as determined by x-ray crystallographic analysis, has indicated that biotin may be capable of forming an intramolecular hydrogen bond in solution. A review of various chemical analogs of the vitamin has shown a close correlation between the possibility of forming such a hydrogen bond and biotin-like activity.
