Chemical constituents of living cells
- Plant/Animal and microbial biomass contain similar types of elements and compounds inside living cells known as biomolecules
- Micromolecules and macromolecules are the two types of biomolecules.
- In order to find organic compounds present in a cell, any tissue is mixed with trichloroacetic acid and then filtered with cheesecloth. The filtrate contains acid soluble substance and acid-insoluble compounds are found in the retentate.
- Primary and secondary metabolites are micromolecules.
- 1° metabolite – Eg: Ethanol, lactic acid, amino acids.
- 2° metabolite – Eg: Antibiotics and pigments.
