C16 Lactosyl(ß) Ceramide (d18:1/16:0) A86576 (Previously 860576) D-lactosyl-ß-1,1' N-palmitoyl-D-erythro-sphingosine

C16 Galactosyl(ß) Ceramide (d18:1/16:0) or D-lactosyl-ß-1,1' N-palmitoyl-D-erythro-sphingosine, also known as Lactosylceramide, is a glycosphingolipid composed of a sphingosine backbone linked to a lactosyl sugar moiety and a palmitoyl fatty acid chain. This molecule is a critical component of cell membranes, playing a significant role in cell signaling, particularly in processes such as cell differentiation, proliferation, and apoptosis.

Lactosylceramide is predominantly found in the outer leaflet of the plasma membrane and is involved in the formation of lipid rafts, specialized membrane microdomains that serve as platforms for various cellular processes.
