Lactase (EC 3.2.1.108) is an enzyme produced by many organisms and is essential to the complete digestion of whole milk.It breaks down the sugar lactose into its component parts, galactose and glucose.
Most monosaccharides have the formula (CH 2 O) x (though not all molecules with this formula are monosaccharides). Examples of monosaccharides include glucose (dextrose), fructose (levulose), and galactose. Monosaccharides are the building blocks of disaccharides (such as sucrose, lactose and maltose) and polysaccharides (such as cellulose and ...
Deficiencies in the protein can result in galactosialidosis or Morquio B syndrome. In E. coli , the lacZ gene is the structural gene for β-galactosidase; which is present as part of the inducible system lac operon which is activated in the presence of lactose when glucose level is low. β-Galactosidase synthesis stops when glucose levels are ...
Maltose (/ ˈ m ɔː l t oʊ s / [2] or / ˈ m ɔː l t oʊ z / [3]), also known as maltobiose or malt sugar, is a disaccharide formed from two units of glucose joined with an α(1→4) bond. In the isomer isomaltose , the two glucose molecules are joined with an α(1→6) bond.
Disaccharidases are glycoside hydrolases, enzymes that break down certain types of sugars called disaccharides into simpler sugars called monosaccharides. In the human body , disaccharidases are made mostly in an area of the small intestine 's wall called the brush border , making them members of the group of "brush border enzymes".
Galactose (/ ɡ ə ˈ l æ k t oʊ s /, galacto-+ -ose, "milk sugar"), sometimes abbreviated Gal, is a monosaccharide sugar that is about as sweet as glucose, and about 65% as sweet as sucrose. [2] It is an aldohexose and a C-4 epimer of glucose. [3] A galactose molecule linked with a glucose molecule forms a lactose molecule.
Unlike other plant-based milk, soy milk has a high protein content similar to cow’s milk. The brand that we looked at had 8 grams per 1-cup serving — equivalent to a cup of whole or reduced ...
Monosaccharides are a carbohydrate that cannot be hydrolyzed into a simpler carbohydrate and are the building blocks of oligosaccharides and polysaccharides. Oligosaccharides are linear or branched chains of monosaccharides attached to one another via glycosidic linkages. The number of monosaccharide units can vary.
