Phytosphingosine (yeast)

Phytosphingosine is a sphingolipid with a hydroxyl group at the C4 position that is found mainly in fungi and plants but also in animals, including humans. It is metabolized to odd-numbered fatty acids with 2-hydroxy palmitic acid (Cay-22679) as an intermediate. Phytosphingosine dose-dependently induces cell death of CHO cells and inhibits carbachol-induced activation of phospholipase D (PLD) in CHO cells transfected with C. elegans muscarinic acetylcholine receptors. It is essential in the heat stress response in S. cerevisiae. [Matreya, LLC. Catalog No. 1330]Formal Name: 2S-amino-1,3S,4R-octadecanetriol. CAS Number: 554-62-1. Synonyms: D-ribo Phytosphingosine.
