| Bioactivity | 4-Hydroxysphinganine C17 base (D-Ribo-phytosphingosine C17 base), also known as D-ribo-phytosphingosine or PHS, is a crucial compound present in the membranes of fungi, plants, bacteria, marine organisms, and mammalian tissues. It plays a vital role in preserving the structural integrity of membranes, regulating cellular growth, and mediating the heat stress response in yeast. Additionally, PHS serves as a precursor for the synthesis of important lipid mediators such as PHS 1-phosphate, inositol phosphorylceramide, and KRN7000 (the α-anomer of galactosylceramide). Furthermore, this phospholipid promotes keratinocyte differentiation, making it a valuable active ingredient in cosmetic formulations. |
