To learn the basic life processes which link the biological systems with the chemical systems.
Origin of Life: elementary idea of prokaryotic and eukaryotic cell, difference between plant and animal cell, cell organelles and their functions: plasma membrane, chloroplast, mitochondria, golgi bodies, endoplasmic reticulum, lysosomes, ribosomes, nucleus.
DNA- Double helical structure of DNA, types of DNA -A, B, C and Z forms, replication.
RNA- RNA structure and its types- r RNA, mRNA, and tRNA
Amino acids: Structure of amino acid, Types of amino acid (essential and non essential), structure of zwitterions, Peptide Bond. Structure of proteins: primary, secondary-α helix and β pleated sheets, tertiary and quaternary structure.
Classification, structure and functions of monosaccharides, disaccharides, polysaccharides - starch, cellulose, glycogen, chitin and pectins. Glycoconjugates: proteoglycans, glycoproteins and glycolipids
Structure and functions of lipids, Saturated and Unsaturated fatty acid, classification- Simple compound and derived lipids (steroids and cholesterol), Synthesis of long chain fatty acids:α-Oxidation and β-Oxidation.
