The molecule is a mannosylinositol phosphorylceramide having a hexacosanoyl group attached to the ceramide nitrogen, with no hydroxylation at C-4 of the long-chain base or on the very-long-chain fatty acid. It derives from an Ins-1-P-Cer(d18:0/26:0). It is a conjugate acid of a Man-1-2-Ins-1-P-Cer(d20:0/26:0)(1-).
