c16 sphingomyelin

C16 Sphingomyelin (d18:1 16:0) (N-Palmitoyl-D-sphingomyelin) 是磷脂双层膜的磷脂类化合物，可用于研究生物膜的活性。

13C C16 Sphingomyelin is an isotopically enriched form of C16 sphingomyelin with carbon-13 occurring on the fatty acid portion. It is intended for use as an internal standard for the quantification of C16 sphingomyelin by GC- or LC-MS. C16 Sphingomyelin is a form of sphingomyelin containing palmitate (16:0) at the variable acylation position. It is the most common form of sphingomyelin found in eggs and is less abundant in the brain and in milk. C16 Sphingomyelin interacts with cholesterol in ordered lipid domains (lipid rafts). Sphingomyelinases remove phosphorylcholine from C16 sphingomyelin to produce C16 ceramide. While ceramides commonly induce apoptosis, ceramides with different fatty acid chain lengths might direct distinct functions and, in some cases, reduce apoptosis.

C16 Ceramide (d16:1, C16:0) 是一种具有生物活性的鞘脂，能够在棕榈酰磷脂 (POPC) 双层中诱导富含棕榈酰鞘磷脂结构域的有序相和凝胶相的形成及其热稳定性。此化合物存在于人红细胞鞘磷脂中。

C22 Sphingomyelin is a naturally occurring form of sphingomyelin . Plasma levels of C22 sphingomyelin positively correlate with hepatic steatosis severity in patients with chronic hepatitis C virus (HCV). C22 Sphingomyelin levels are decreased in T-47D mammary epithelial cells and increased in MDA-MB-231 breast cancer cells relative to C16 sphingomyelin .
