reveals divergence in the metabolism of the essential vitamin biotin with genes for either synthesis (bioF_2ADB) and/or transport (bioY). Streptavidin blotting confirmed the presence of a single biotinylated protein inChlamydia. As a first step in unraveling the need for divergent biotin ...
Biotin exhibits a surprisingly high skin lightening effect when it is administered together with vitamin C or a vitamin C derivative. Claimed is the use of biotin alone, preferably however with vitamin C or a derivative thereof, for the preparation of a cosmetic composition or of a pharmaceutical...
