Application:

  • Synthesis of lactose lauryl ester in organic solvents using aluminosilicate zeolite as a catalyst.: This research explores the synthesis of lactose lauryl ester, utilizing D-lactose monohydrate and organic solvents in the presence of aluminosilicate zeolite as a catalyst, highlighting its potential applications in food chemistry and surfactants (Enayati et al., 2019 ).

  • Synthesis and characterization of lactose fatty acid ester biosurfactants using free and immobilized lipases in organic solvents.: The paper presents the synthesis and characterization of lactose fatty acid esters using D-lactose monohydrate and various lipases, focusing on their potential as biosurfactants in food and cosmetic industries (Enayati et al., 2018 ).
Biochem/physiol Actions: Lactose is a dissacharide formed by the condensation of one galactose and one glucose molecule. Lactose is the major sugar in the milk of most species, typically present between 2-8%. The enzyme lactase hydrolyzes lactose to its constituent monosaccharides. In neonates, glucose released via the action of lactase is a major energy source.
