Following are the characteristics of polysaccharides. Which of them is correct regarding all polysaccharides?

Correct answer: A. High molecular weight

  • A. High molecular weight
  • B. Insoluble in water
  • C. Tasteless
  • D. Polymers of glucose

Explanation

The correct answer is High molecular weight. Polysaccharides are large and complex carbohydrates made up of many monosaccharide units, which gives them a high molecular weight. Option B, insoluble in water, is incorrect because some polysaccharides can dissolve in water or form colloidal solutions, depending on their structure. Option C, Tasteless, is also incorrect because not all polysaccharides are tasteless; their taste can vary depending on their specific type and structure. Option D, Polymers of glucose, is also incorrect, as not all polysaccharides are polymer of glucose.
