N-[(1S,2R,3E)-1-[(4-O-β-D-Galactopyranosyl-β-D-glucopyranosyl)oxymethyl]-2-hydroxy-3-heptadecenyl]hexadecanamide

C16 Lactosylceramide is an endogenous bioactive sphingolipid.¹ It forms membrane microdomains with Lyn kinase and the α_i subunits of inhibitory G protein-coupled receptors (GPCRs), suggesting a role in cell signaling. Plasma levels of C16 lactosylceramide are elevated in insulin-resistant cattle.² C16 Lactosylceramide is also upregulated in a mouse model of Niemann-Pick type C1 disease, a neurodegenerative cholesterol-sphingolipid lysosomal storage disorder.³

LacCer (d18:1/16:0) (C16 Lactosylceramide (d18:1/16:0)) is an endogenous bioactive sphingolipid that can form membrane microdomains with Lyn kinase and the αi subunits of inhibitory G protein-coupled receptors (GPCRs). The levels of LacCer (d18:1/16:0) are elevated in the plasma of insulin-resistant cattle. In a mouse model of Niemann-Pick type C1 disease (a neurodegenerative cholesterol-sphingolipid lysosomal storage disorder), the expression of LacCer (d18:1/16:0) is also upregulated. LacCer (d18:1/16:0) can be used in research on metabolic diseases and neurodegenerative diseases[1][2][3].

ChEBI: Beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1)-N-hexadecanoylsphingosine is a beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1')-N-acylsphingosine in which the acyl group specified is hexadecanoyl. It has a role as a mouse metabolite. It is functionally related to a hexadecanoic acid.
