Metabolite Identification
Common NameN-stearoylphytosphingosine
DescriptionN-stearoylphytosphingosine is a ceramide, specifically a sphingolipid, characterized by the attachment of a stearoyl group to the phytosphingosine backbone. This compound features a long-chain fatty acid moiety, which contributes to its structural properties and biological functions. Chemically, N-stearoylphytosphingosine can form multilamellar and unilamellar vesicles, influencing membrane dynamics and stability, as evidenced by studies demonstrating its impact on the structure and properties of dimyristoylphosphatidylcholine vesicles (PMID:16202987 ). Additionally, it has been shown to participate in cellular responses to UVB irradiation, where it acts as a co-stimulator in keratinocytes at low concentrations, highlighting its role in skin biology (PMID:25078364 ). The presence of N-stearoylphytosphingosine in cellular membranes suggests its involvement in various signaling pathways and cellular processes, particularly in the context of skin health and integrity.
