The molecule is an inositol phosphomannosylinositol phosphoceramide compound having an inositol 1-phosphoryl group linked to the mannose residue (at the 6-position) and a hexacosanoyl group amide-linked to a C18 phytosphingosine base, with no hydroxylation of the C26 very-long-chain fatty acid. It has a role as a Saccharomyces cerevisiae metabolite. It derives from a Man-1-2-Ins-1-P-Cer(t18:0/26:0). It is a conjugate acid of an Ins-1-P-6-Man-1-2-Ins-1-P-Cer(t18:0/26:0)(2-).
