Lesson 17: Proteins, fats, carbohydrates,water & nucleic acids

Hi,

This powerpoint slides show beautiful models of organic molecules. I am sure it will enhance your learning experience.

Revise the following concepts covered by this set of slides:
  • lipids- structural formulae, functions
  • water-polar molecule, functions in organism due to its high solubility, heat capacity, high latent heat of vaporisation, capillarity, surface tension
  • carbohydrates-mono-, di- and polysaccharides
  • condensation of monosaccharides to form the larger di- and polysaccharides
  • starch, glycogen, cellulose
  • protein-condensation of amino acids to form polypeptides
  • functions of proteins
  • nucleic acids and DNA
  • nucleotide-phosphate, pentose and base
  • cytosine, thymine, adenine and guanine
  • DNA replication, triplet code in genetic codes
  • protein synthesis- mRNA formation in nucleus
  • mRNA in cytoplasm attaching to ribosome
  • tRNA and formation of amino acids




Cheers
