Disaccharidase

From Wikipedia, the free encyclopedia

Disaccharidases are a type of glycoside hydrolases, enzymes that break down disaccharides into monosaccharides.

[edit] Examples of disaccharidases

• Lactase (breaks down lactose into glucose and galactose)
• Maltase (breaks down maltose into 2 glucoses)
• Sucrase (breaks down sucrose into glucose and fructose)
• Trehalase (breaks down trehalose into 2 glucoses)

For a thorough scientific overview of small-intestinal disaccharidases, one can consult chapter 75 of OMMBID.^[1] For more online resources and references, see inborn error of metabolism.
