Carbohydrates are classified into three major groups on the basis of their behavior towards hydrolysis. Which of the following statements regarding this classification is incorrect?
Options
- AMonosaccharides cannot be hydrolysed further to give simpler units of polyhydroxy aldehydes or ketones.
- BCarbohydrates that yield two to ten monosaccharide units on hydrolysis are called oligosaccharides.
- CPolysaccharides yield a large number of monosaccharide units on hydrolysis and are generally sweet in taste.
- DSucrose, maltose, and lactose are common examples of oligosaccharides.
Correct answer
C. Polysaccharides yield a large number of monosaccharide units on hydrolysis and are generally sweet in taste.
Step-by-step solution
Carbohydrates are classified into monosaccharides, oligosaccharides, and polysaccharides based on their hydrolysis behavior.
Monosaccharides are the simplest carbohydrates and cannot be hydrolysed further into simpler units of polyhydroxy aldehydes or ketones.
Oligosaccharides yield two to ten monosaccharide units on hydrolysis. Common examples include sucrose, maltose, and lactose, which are disaccharides.
Polysaccharides yield a large number of monosaccharide units on hydrolysis. However, unlike monosaccharides and oligosaccharides, polysaccharides are generally not sweet in taste and are therefore referred to as non-sugars. Examples include starch, cellulose, and glycogen.
Thus, the statement claiming that polysaccharides are generally sweet in taste is incorrect.
Answer: Polysaccharides yield a large number of monosaccharide units on hydrolysis and are generally sweet in taste.
