Question
Consider the following statements regarding
carbohydrates:(I) Monosaccharides are carbohydrates that cannot be hydrolysed into simpler polyhydroxy aldehydes or ketones.(II) Carbohydrates that produce many monosaccharide units upon hydrolysis are known as oligosaccharides.Solution
Monosaccharides are the simplest form of carbohydrates and cannot be broken down further by hydrolysis. Examples include glucose and fructose.Statement II is incorrect because carbohydrates that yield a large number of monosaccharide units upon hydrolysis are known as *polysaccharides*, not oligosaccharides. Oligosaccharides produce a few monosaccharide units (typically 2β10).Therefore, only Statement I is correct.
