Brit.

/ˈlakteɪz/,

/ˈlakteɪs/, U.S.

/ˈlækˌteɪs/,

/ˈlækˌteɪz/

Etymology: < French lactase (M. W. Beijerinck 1889, in Arch. néerl. d. Sci. exactes et nat. XXIII. 434), < lact-ose lactose n.: see -ase suffix.

Biochemistry.

Any enzyme which catalyses the hydrolysis of lactose to glucose and galactose.

1891 Jrnl. Royal Microsc. Soc. 374 The fermentation [of milk sugar] is effected by a diastase distinct from invertin, which he calls lactase.

1906 Jrnl. Physiol. 35 28 The conclusion is from these experiments that lactase is distributed fairly equally through the whole of the mucous membrane of the intestine.

1910 Practitioner June 823 The hydrolysis is brought about by means of enzymes, such as..lactase and glucase.

1911 Encycl. Brit. XIX. 923/2 The presence of lactase has been much discussed.

1959 R. Jenness & S. Patton Princ. Dairy Chem. iii. 80 There are at least three significant origins of lactase enzymes which may be used for the hydrolysis of lactose. These are: (a) certain species of yeasts..; (b) the intestinal mucosa of mammals..; and (c) β-galactosidase from almonds.
