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.
