Chapter 14 | Biomolecules


1. Substances or molecules occurring in living systems are called biomolecules.

2. Carbohydrates are polyhydroxy aldehydes and ketones. These are classified as monosaccharides, disaccharides and polysaccharides.

3. On the basis of their reducing nature, carbohydrates can be grouped as reducing sugars and non-reducing sugars.

4. Glucose exists in two cyclic forms viz, a-D-glucose and

B-D-glucose.

5. Amino acids are the smallest units of proteins. These consist of an amino and a carboxyl group.

6. Structure of proteins can be studied at four levels-primary, secondary, tertiary and quaternary.

7. Due to temperature change or pH change, secondary and tertiary structures are destroyed but the primary structure remains intact. The process is called denaturation of proteins.

8. Enzymes are biocatalysts and are specific in function.

9. Vitamins B and C are water-soluble and vitamins A, D, E and K are fat-soluble.

10. Nucleic acids are the polymers of nucleotides. DNA and RNA are two nucleic acids.

11. DNA-Deoxyribose nucleic acid- transmits the hereditary characters from one generation to another. RNA-Ribonucleic acid- synthesises protein in the cell.

12. Nucleic acid consists of a pentose sugar, nitrogenous base and phosphoric acid.

13. A combination of base and sugar is called nucleoside.

14. A combination of nucleoside and phosphoric acid is called a nucleotide.

15. DNA has a double-stranded a-helix structure.
