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.

About Carbohydrates
Carbohydrates are organic compounds classified as monosaccharides, disaccharides and polysaccharides according to their structure and hydrolysis products. The topic covers glycosidic bonds, glucose and fructose, sucrose, lactose and maltose, starch, glycogen and cellulose, along with their roles in energy storage, structural support and food tests.
