E17110 significantly decreased cellular lipid accumulation and promoted cholesterol efflux in RAW264.7 macrophages.

Taurohyocholic acid (THCA) is a taurine-conjugated form of the porcine-specific primary bile acid hyocholic acid .1THCA inhibits precipitation of cholesterol crystals by stabilizing cholesterol in the liquid-crystalline phase.2It prevents cholestasis and cellular necrosis induced by taurolithocholic acid in isolated rat livers.3THCA levels are increased in the urine of patients with hepatitis B-induced cirrhosis.4

Cholesteryl lignocerate is a cholesterol ester that has been found in human meibum. Cholesteryl lignocerate can be hydrolyzed by cellular extracts from cultured human skin fibroblasts isolated from healthy individuals but not patients with cholesteryl ester storage disease (CESD) or Wolman disease.

Sphingomyelins (SMs) are bioactive sphingolipids found in mammalian cell membranes.1SMs make up 2-15% of the total organ phospholipid population but are found at higher concentrations in the brain and myelin sheaths surrounding peripheral nerves. They interact with cholesterol to control its distribution within cellular membranes and maintain cholesterol homeostasis in cells. SMs undergo hydrolysis by sphingomyelinase to form ceramides, which are sphingolipid mediators of intracellular signaling.2This product is a mixture of SMs, with variable fatty acyl chain lengths, isolated from buttermilk.
