Application
D-ribo-phytosphingosine (C17 base) has been used as a standard for the quantification of total plant long-chain bases (LCB) by gas chromatography-mass spectrometry (GC-MS).
Biochem/physiol Actions
D-ribo-phytosphingosine helps in maintaining the structural integrity of membrane. It also controls cellular growth and mediates the heat stress response of yeast. In addition, PHS acts as a precursor for synthesis of various key lipid mediators including PHS 1-phosphate, inositol phosphorylceramide and KRN7000 (α-anomer of galactosylceramide). This phospholipid also has an ability to stimulate keratinocyte differentiation. Therefore, PHS is used as an active constituent in cosmetic formulations.
General description
D-ribo-phytosphingosine (C17 base), also known as 4D-hydroxysphinganine or PHS, is widely found in membranes of fungi, plants, bacteria, marine organisms and mammalian tissues.
