su·crose α-d-glu·co·si·dase(sū'krōs glū'kō-hī'drō-lās),
An enzyme catalyzing the hydrolysis of sucrose and maltose. The enzyme isolated from the intestinal mucosa will also act on isomaltose (that is, it contains a subunit that acts on isomaltose separately). A deficiency of this enzyme results in defective digestion of sucrose and linear α 1,4-glucans

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 α1,4-glucans.
