Biochemistry - Carbohydrates Part I - NEET Pattern

Inulin is a type of carbohydrate that is mainly composed of fructose molecules. It is not considered a heteropolymer because it is made up of a single type of monosaccharide, fructose, rather than a combination of different monosaccharides. Therefore, the correct answer is that inulin is not a hetero-polymer and is mainly made up of fructose.

Carbohydrates can be converted to lipids through a process called lipogenesis, where excess glucose molecules are converted into fatty acids and then stored as triglycerides in adipose tissue. However, the conversion of lipids to carbohydrates is not a common physiological process in humans. While lipids can be broken down into fatty acids and used for energy, they are not typically converted back into glucose molecules. Therefore, Statement A is correct as it is supported by scientific evidence, while Statement B is incorrect as it does not provide a valid reason for Statement A.

β-D-glucopyranose and β-D-mannopyranose are not epimers because they do not differ only in the fourth carbon. Epimers are stereoisomers that differ in the configuration of only one chiral carbon atom. In this case, glucopyranose and mannopyranose differ in the configuration of multiple carbon atoms, not just the fourth carbon.

Sucrose is a disaccharide composed of glucose and fructose molecules. It is not a reducing sugar because it does not have a free aldehyde or ketone group that can participate in a reducing reaction. Sucrose is often referred to as an inert sugar because it does not undergo chemical reactions easily. The given answer provides the specific chemical structure of sucrose, indicating that it is composed of an α-D-glucopyranosyl unit linked to a β-D-fructofuranoside unit through a glycosidic bond.
