4-Hydroxysphinganine (C17 base)

Description

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 ?-anomer of galactosylceramide . Furthermore, this phospholipid promotes keratinocyte differentiation, making it a valuable active ingredient in cosmetic formulations.
