Which one of the following sugar does not have same empirical formula as that of carbohydrate?
1 Maltose
2 Galactose
3 Digitoxose
4 Glycogen
Explanation:
Exp: C Digitoxose, component of cardiac glycosides found in Digitalis purpurea. It is a glycoside made up of one molecule of digioxigenin and three molecules of sugar digitosose. Chemical formula is \(\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{4}\) obtained by hydrolysis of glycoside of Digitalis. They are used as conventional drugs for over 200 years.

Which one of the following carbohydrates is a heteropolysaccharide?
1 Cellulose
2 Starch
3 Glycogen
4 Hyaluronic acid
Explanation:
Exp: D Carbohydrate are homopolysaccharides or heteropolysaccharides. Heteropolysaccharides contains two or more units of monosaccharides or polysaccharides, do not have a fixed molecular weight. Hyaluronic acid made up of \(\mathrm{N}\)-acetyl-glucosamine -6phosphate and glucoronic acid. It is found in connective tissue and skin. It functions in signaling and also acts as lubrication of synovial joints and helps in joint movement.

Choose the correct statements (I) Inulin is a polymer of glucose (II) Cellulose does not contain complex helices (III) Starch is a polymer with helical secondary structure (IV) Store house of energy in animal tissue is glycogen Options:
1 I, IV, III
2 I, III, II
3 II, IV, I
4 II, III, IV
Explanation:
Exp: D (i) Inulin is a polymer of fructose. (ii) Cellulose does not contain complex helices and hence cannot hold iodine and remain colourless. (iii) Starch can hold iodine molecules in its helical secondary structure and hence it gives colour with iodine. (iv) Glycogen is a homopolysaccharide found in the liver and muscles of animals, where it is used to store energy.

Marcomolecule of Chitin are -
1 Simple polysaccharide
2 Nitrogen containing polysaccharide
3 Phosphorus containing polysaccharide
4 Sulphur containing polysaccharide
Explanation:
Exp: B Chitin is a nitrogen containing modified polysaccharide made up of units of \(\mathrm{N}\)-acetyl-dglucosamine. Macromolecule chitin is an example complex structural heteropolysaccharide. It has nitrogen containing glucose derivatives such as Nacetyl glycosamine. It ispresent as the structural components of fungal cell and exoskeleton of arthopods etc.
