Lactose,maltose and sucrose are the important:

Correct answer: B. disaccharides

  • A. polysaccharides
  • B. disaccharides
  • C. monosaccharides
  • D. oligosaccharides

Explanation

Disaccharides are carbohydrates composed of two sugar units joined by a glycosidic bond. Lactose is made up of glucose and galactose, maltose is made up of two glucose molecules, and sucrose is made up of glucose and fructose.In summary, lactose, maltose, and sucrose are disaccharides, which are composed of two sugar units bonded together. Polysaccharides are more complex carbohydrates with multiple sugar units, monosaccharides are single sugar units, and oligosaccharides have a small number of sugar units, typically 3 to 10.
