Abstract
Summary
Treatment of pantethine with sodium sulfide, cysteine, glutathione, β-mercaptoethylamine, or several other thiols followed, in some cases, by oxidation with iodine resulted in formation of a series of new compounds with growth-promoting activity for Lactobacillus helveticus 80. These compounds appear to be mixed disulfides. The natural occurrence of similar mixed disulfides formed from pantetheine and other naturally occurring thiols may explain in part the presence of several chromatographically distinct forms of LBF in natural materials.
