The molecule is a ceramide phosphoinositol compound having a hexacosanoyl group attached to the ceramide nitrogen and no hydroxylation at C-4 of the long-chain base or at C-2 or C-3 of the very-long-chain fatty acid. It has a role as a Saccharomyces cerevisiae metabolite. It derives from a N-hexacosanoylsphinganine. It is a conjugate acid of an Ins-1-P-Cer(d18:0/26:0)(1-).
