1-Lauroyl-rac-glycerol is a monoacylglycerol that contains lauric acid at the sn-1 position. It is active against pneumococci, group A streptococci, β-hemolytic non-group A streptococci, corynebacteria, N. asteroides, micrococci, S. aureus, S. epidermidis, and C. albicans (MICs = 0.045-0.09 μmol/ml).1 It is also active against a panel of 16 fungi when used at a concentration of 0.1% in growth media.2 Dietary administration of 1-lauroyl-rac-glycerol (2% w/w) reduces S. mutans colony forming units (CFUs) on tooth surfaces and severity of sucrose-induced dental caries in rats.3
