tre·ha·lase

(trē'hă-lās), [MIM*275360]
A glycosidase secreted in the duodenum that hydrolyzes α-glycosidic 1,1 bonds; an absence or deficiency of this enzyme will lead to deficient digestion of trehalose (autosomal recessive).

trehalase

(trĭ-hä′lās′, -lāz′)
n.
An enzyme that catalyzes the hydrolysis of trehalose.

trehalase

(trē-hā′lās)
The enzyme that cleaves the bond between glucose molecules in the disaccharide, trehalose.
