Biomolecules

Assertion :Adjacent monosaccharides are held by glycosidic bonds to form polysaccharides. Reason : Monosaccharides cannot be hydrolysed further into smaller components.

Assertion: Two sugar units are joined by 1,2-glycosidic bond in sucralose. Reason : Sucralose contains $C_1$-glucose and $\mathrm{C}_2$-fructose glycosidic bond.

Two alleles of the same gene possess chemical variation of

Assertion : Glucose does not give 2, 4-DNP test. Reason : Glucose exists in cyclic hemiacetal form.

Assertion : Oxidation of glucose by $\mathrm{Br}_2$-water gives saccharic acid. Reason : $\mathrm{Br}_2$-water oxidises $-\mathrm{CHO}$ and -OH group.

Which of the following statements is incorrect?

Which of the following sets of amino acids contains only essential amino acids?

Assertion: Nucleotides are phosphate esters of nucleosides. Reason: The various nucleotides in nucleic acids are linked either through purine or pyrimidine bases.

Assertion : Carbohydrates are more suitable for the production of energy in the body than proteins and fats. Reason: Carbohydrates can be stored in the tissues as glycogen and can be used for the production of energy,…

Assertion : A solution of sucrose in water is dextrorotatory. But on hydrolysis in the presence of a little hydrochloric acid, it becomes laevorotatory. Reason : Sucrose on hydrolysis gives unequal amounts of glucose…

Assertion : Solubility of proteins is minimum at the isoelectric point. Reason : At isoelectric point, protein molecule behaves as a zwitter ion.

'Tocopherol' is the chemical name of
