Enzymatic synthesis and characterization of maltoheptaose-based sugar esters

In this study, maltoheptaose (G7)-based sugar esters were synthesized from maltoheptaose and fatty acids (C10–C16) using a commercial lipase. With the exception of dimethyl sulfoxide (DMSO; 76.4%, w/v), G7 showed only limited solubility in organic solvents. Among the fatty acids, palmitic acid (PA) was the best substrate for G7-based ester formation. G7-PA ester was successfully synthesized as the monoester structure exclusively in 10% DMSO of...
