Topics in Biomolecules

1

Chemical Composition of Living Tissues

  • Living tissues and non-living matter contain many of the same elements, but carbon and hydrogen are relatively more abundant in living organisms.
  • Chemical analysis of tissue separates compounds into an acid-soluble pool and an acid-insoluble fraction.
  • The acid-soluble pool contains compounds with molecular weights from 18 to around 800 daltons.
2

Primary and Secondary Metabolites

  • Primary metabolites are compounds such as amino acids, sugars, fatty acids, glycerol, nucleotides, nucleosides, and nitrogen bases.
  • Secondary metabolites are compounds such as rubber, gums, cellulose, alkaloids, flavonoids, essential oils, antibiotics, coloured pigments, scents, and spices.
  • Primary metabolites have direct roles in normal physiological processes.
3

Amino Acids and Proteins

  • Amino acids are organic compounds containing an amino group and an acidic carboxyl group as substituents on the same α-carbon.
  • Amino acids are substituted methanes with four groups attached to the α-carbon: hydrogen, carboxyl group, amino group, and R group.
  • Only 20 types of amino acids occur in proteins.
4

Lipids

  • Lipids are generally water insoluble.
  • Fatty acids have a carboxyl group attached to an R group.
  • The R group of fatty acids may range from 1 to 19 carbons.

Key Concepts

Central concept: Biomolecules are the chemical compounds of living organisms, ranging from small molecules in the acid-soluble pool to large macromolecules such as proteins, nucleic acids, and polysaccharides, with enzymes and biological structure arising from their organisation and interactions.
