What is Lactose?
Well 'lactose' is the name of the sugar found in milk.The other names are: milk sugarand officially (IUPAC): β-D-galactopyranosyl-(1->4)-D-glucose
How is lactose classified?
Disaccharide made of two hexo-aldoses: galactose and glucose. IUPAC name: beta-D-galactopyranosyl-(1-4)-D-glucose.
Is lactose a monosacchardie or a disaccharode solution?
Lactose is a disaccharide that consists of β-D-galactose and β-D-glucose fragments bonded through a β1-4 glycosidic linkage. It's also a solid by the way.
What are some solutes in low-fat chocalate milk?
lactose, Chocolate
What foods shall you avoid if you have lactose sensitivity?
Foods that contain lactose. You may not need to completely avoid foods and beverages that contain lactose —such as milk or milk products. If you avoid all milk and milk products, you may get less calcium and vitamin D than you need. People with lactose intolerance can handle different amounts of lactose.
Does Lactose-free milk have magnesium?
Lactose-free varieties of milk provide the same nutrients as regular milk. The nutrients in an 8-oz. glass of nonfat, lactose-free milk include 8.3 g of protein; 12.5 g of sugars; 0.2 g of fat; 5 mg of cholesterol; 300 mg of calcium; 250 mg of phosphorus; 380 mg of potassium; 27 mg of magnesium; 150 micrograms of vitamin A; and 2.9 micrograms of vitamin D. The vitamin D, calcium, phosphorus and magnesium in lactose-free milk help support your bone health.
Which of the following is a characteristic of yogurt?
A) Bacteria in yogurt produce lactase B) The lactose content of yogurt is about one-half that of milk C) Yogurt is poorly tolerated in lactose-intolerant people D) There are only trace amounts of lactose present in yogurt
What chemical reaction does lactase catalyze?
Acetal formation (glycosidic linkage) between glucose and galactose by condensation reaction.It can also be seen as dimerisation of two monosaccharides (Glu + Gal) to one disaccharide(Lactose is: β-D-galactopyranosyl-(1→4)-D-glucose)
What is the positive result for mucic acid test?
When galactose is oxidized by nitric acid, insoluble mucic acid is formed. A positive result is the formation of a precipitate. Lactose is a dimer of glucose and galactose. The nitric acid will hydrolyze the dimer and so lactose will also give a positive result.
Which is not knows to adversely affect calcium balance A high-fiber diet B lactose in the diet C phytic acid in the diet D phosphorus in the diet at a level 3 times that of calcium?
Lactose in the diet
Which one of the following choices is a simple sugar A Glucose B Orange juice C Lactose D Chocolate?
A. Glucose is a simple sugar (a monosaccharide). Lactose is also a sugar, but it is a disaccharide made up of galactose and glucose.
Equation for the formation of alpha d-lactose from beta d-galactose and alpha d-glucose?
The general formula is (CH2O)n (simple sugars) or Cx(H20)y. It can get more complexed though, but it all depends on what you are trying to do.
