Lipid rafts are small (10-200nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched domains that compartmentalize cellular processes.”
~ 2006 Keystone Symposium
Cholesterol and sphingolipid-enriched membrane microdomains or platforms
Cholesterol levels double
Sphingomyelin levels elevated by 50%
Concentrate and segregate proteins within the plane of the bilayer
More ordered and tightly packed than surrounding bilayer
Float freely in Lc bilayer
