Medchemexpress LLC LacCer (d18:1/16:0) (C16 Lactosylceramide (d18:1/16:0)) | 4201-62-1 | C46H87NO13 | 1 MG
LacCer (d18:1/16:0) is an endogenous bioactive sphingolipid. It forms membrane microdomains with Lyn kinase and the αi subunits of inhibitory G protein-coupled receptors (GPCRs). Its levels are elevated in the plasma of insulin-resistant cattle and upregulated in a mouse model of Niemann-Pick type C1 disease. It can be used for research on metabolic and neurodegenerative diseases.
- Endogenous bioactive sphingolipid
- Forms membrane microdomains with Lyn kinase and αi subunits of inhibitory GPCRs
- Elevated in insulin-resistant cattle plasma
- Upregulated in Niemann-Pick type C1 disease mouse model
- Used in research on metabolic diseases
- Used in research on neurodegenerative diseases
