| Common Name | Inositol-P-ceramide |
|---|
| Description | Inositol-P-ceramide is found in the sphingolipid metabolism pathway. Inositol-P-ceramide is formed when α hydroxyphytoceramide and inositol phosphate react. The reaction is catalyzed by inositol phosphoceramide synthase. Inositol-P-ceramide reacts with GDP-α-D-mannose to produce mannosyl-inositol-phosphorylceramide and GDP. This reaction is catalyzed by inositol phosphorylceramide mannosyltransferase. |
