TLDR Cystine is crucial for forming keratin in hair, wool, and nails.
The study explores the role of sulfhydryl compounds in sulfur metabolism related to skin physiology, both in normal and pathological states. It highlights the significance of cystine in forming keratin-containing tissues like hair, wool, and nails. Sulfur in the skin is primarily in organic forms, mainly as cystine and cysteine, with other compounds like glutathione and methionine also present. The research focuses on the total sulfur content in the skin rather than individual compounds.
Human hair keratins can self-assemble and support cell growth, useful for biomedical applications.
