Verified by Toppr

  • Sugars are categorized into monosaccharides or disaccharides.
  • Monosaccharides are made up of one single unit of sugar and thus cannot be hydrolyzed further into simpler compounds. Examples:- galactose, glucose, and fructose.
  • These are the building blocks of other carbohydrates like disaccharides and polysaccharides.
  • Disaccharides are made up of two monosaccharides linked by glycosidic linkage and will be again broken back down into the latter during digestion
  • Sucrose is the scientific name for table sugar and is a disaccharide.

So the correct answer is option D.
