Study Notes
Components of Retentate
- The retentate obtained from living tissue treated with trichloroacetic acid contains proteins, lipids, and nucleic acids.
Lipids
- Lipids are biomolecules characterized by being water-insoluble and composed of fatty acids and glycerol.
- The main characteristic of lipids is being water-insoluble.
Nucleotides
- Nucleotides are building blocks of nucleic acids, such as DNA and RNA.
- The main function of nucleotides in living organisms is to store and transmit genetic information.
Elemental Analysis
- The purpose of elemental analysis of living tissue is to determine the elemental composition of the tissue.
Molecular Weight Range of Biomolecules
- Micromolecules or biomolecules obtained from living tissues have a molecular weight range of <1000-5000 daltons.
- Macromolecules obtained from living tissues have a molecular weight range of >5000-100000 daltons.
Amino Acids
- The main characteristic of amino acids is being the building blocks of proteins.
