vitamin B complex

Verwenden

Growth factor present in minute amounts in every living cell. Plays an indispensable role in numerous naturally occurring carboxylation reactions. Occurs mainly bound to proteins or polypeptides. The richest sources are liver, kidney, pancreas, yeast, and milk. The biotin content of cancerous tumors is higher than that of normal tissue.

Definition

ChEBI: An organic heterobicyclic compound that consists of 2-oxohexahydro-1H-thieno[3,4-d]imidazole having a valeric acid substituent attached to the tetrahydrothiophene ring. The parent of the class of biotins.

Trademarks

Bioepiderm (Sterling Winthrop).

Sicherheitsprofil

An experimental teratogen. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx and SOx.

läuterung methode

D-(+)-Biotin crystallises from hot water in fine long needles with a solubility of 22 mg/100mL at 25o. Its solubility in 95% EtOH is 80 mg/100 mL at 25o. Its isoelectric point is at pH 3.5. Store solid and solutions under sterile conditions because it is susceptible to mould growth. [Confalone J Am Chem Soc 97 5936 1975, Wolf et al.
