Objective
  To impart advance knowledge of carbohydrate, lipid, and nitrogen metabolism.

Theory

UNIT I
  Biosynthesis and degradation of hexose phosphate, biosynthesis of sucrose and its utilization, translocation, breakdown and storage, respiratory metabolism, glycolate pathway, pentose phosphate pathway, localization and evidence for its operation.

UNIT II
  Starch synthesis, accumulation and breakdown in seeds during germination and in leaves, regulation of starch metabolism. Organic acid synthesis and its regulation, crassulacean acid metabolism and its regulation.

UNIT III
  Classification of lipids and fatty acids - major, minor and unusual fatty acids. Fatty acids synthesis, chain elongation and unsaturated fatty acid biosynthesis. Lipid biosynthesis - triglycerides, phospho lipids, glycol lipids. Membrane lipid structure and function. Fat metabolism during germination and seed development- Beta oxidation, glyoxylate cycle, alpha oxidation.

UNIT IV
  Nitrogen cycle, nitrogen fixation, nitrification and denitrification, nitrate and ammonia assimilation and regulation, transamination, amino acid synthesis, non-protein amino acids synthesis, nitrogen redistribution in cell, nitrogen inter conversion and transport during plant development, nodule metabolism, protein synthesis and its metabolism, sulphur metabolism. Biosynthesis and breakdown of nucleic acids.
