Is sphingomyelin a sphingolipid
WitrynaSphingomyelin or ceramide 1-phosphocholine is a sphingophospholipid that consists of a ceramide unit with a phosphorylcholine moiety attached to position 1 of the sphingoid base component.

Sphingomyelin (SPH, ˌsfɪŋɡoˈmaɪəlɪn) is a type of sphingolipid found in animal cell membranes, especially in the membranous myelin sheath that surrounds some nerve cell axons. It usually consists of phosphocholine and ceramide, or a phosphoethanolamine head group; therefore, sphingomyelins … Zobacz więcej Composition Sphingomyelin consists of a phosphocholine head group, a sphingosine, and a fatty acid. It is one of the few membrane phospholipids not synthesized from glycerol. … Zobacz więcej Membranes The membranous myelin sheath that surrounds and electrically insulates many nerve cell Zobacz więcej • Ball-and-stick model of sphingomyelin • Skeletal formula of sphingomyelin • ceramide Zobacz więcej • Sphingomyelins at the U.S. National Library of Medicine Medical Subject Headings (MeSH) Zobacz więcej Synthesis The synthesis of sphingomyelin involves the enzymatic transfer of a phosphocholine from phosphatidylcholine to a ceramide. The first committed step of sphingomyelin synthesis involves the condensation of Zobacz więcej Sphingomyelin can accumulate in a rare hereditary disease called Niemann–Pick disease, types A and B. It is a genetically-inherited disease caused by a deficiency in the lysosomal enzyme acid sphingomyelinase, which causes the accumulation … Zobacz więcej Witryna8 lip 2024 · The most important enzymes involved in the synthesis of sphingolipids and their metabolites are ceramidase, which yields sphingosine from ceramide; Sphks, which acts upon sphingosine to produce S1P; both sphingomyelinase (SMase) and sphingomyelin synthase act on ceramide to synthesize sphingomyelin; and …
