1-Decanoyl-rac-glycerol is a monoacylglycerol that contains decanoic acid at the sn-1 position. It inhibits the growth of B. cereus, S. typhimurium, and E. coli when used at a concentration of 1 mg/ml and S. aureus when used at a concentration of 0.5 mg/ml. 1-Decanoyl-rac-glycerol is an agonist of transient receptor potential vanilloid 1 (TRPV1) that induces calcium influx in HEK293 cells expressing the human receptor (EC50 = 12.6 μM). It is an emulsifying agent and has been used to increase the storage stability of mayonnaise and viscoelasticity of processed cheese.
