| sucrose | Nonreducing disaccharide, _ D glucopyranosyl _ D fructofuranose. (18 Nov 1997) |
| sucrose alpha-d-glucohydrolase | <enzyme> An enzyme hydrolyzing sucrose and maltose; in a complex with isomaltase; hence, hydrolyzes both sucrose and isomaltose; found in the intestinal mucosa; a deficiency of this enzyme results in defective digestion of sucrose and linear a1,4-glucans.

| acyl-malonyl-ACP synthase | <enzyme> An enzyme condensing malonyl-ACP and acyl-cys-protein to 3-oxoacyl-ACP + cys-protein + CO2, and similar reactions, as steps in fatty acid synthesis; cys-protein is also a part of the fatty acid synthase complex. Synonym: acyl-malonyl-ACP synthase, beta-ketoacyl-ACP synthase. (05 Mar 2000) |
