Q. What are the components of Monosaccharides?

A
Glucose
B
fructose
C
galactose
D
all the above
Solution:
  • Monosaccharides also called simple sugars, are the simplest form of sugar and the most basic units of carbohydrates.
  • They cannot be further hydrolyzed to simpler chemical compounds.
  • They are usually colorless, water-soluble, and crystalline solids.
  • Some monosaccharides have a sweet taste.
  • Examples of monosaccharides include glucose (dextrose), fructose (levulose), and galactose.
  • Monosaccharides are the building blocks of disaccharides (such as sucrose and lactose) and polysaccharides (such as cellulose and starch).
  • The most important monosaccharide, glucose, is a hexose.
  • Monosaccharides with eight or more carbons are rarely observed as they are quite unstable.
  • In aqueous solutions monosaccharides exist as rings if they have more than four carbons.
