The molecule is a mannosylinositol phosphorylceramide compound having a hexacosanoyl group attached to the ceramide nitrogen, hydroxylation at C-4 of the C18 sphingoid base, and hydroxylation at C-2 and C-3 of the C26 very-long-chain fatty acid. It has a role as a Saccharomyces cerevisiae metabolite. It derives from an Ins-1-P-Cer(t18:0/2,3-OH-26:0). It is a conjugate acid of a Man-1-2-Ins-1-P-Cer(t18:0/2,3-OH-26:0)(1-).
