Aim: The objective is to identify specific chemical substances within a cell and to be able to verify the presence or absence of each one in a cell or food substance for future testing. Hypothesis: The identification of each biomolecular chemical substance should be verified successfully‚ as well as determining if it is present or absent in the cell(s). Theoretical Base: A biomolecule is a substance that naturally occurs in living organisms. Biomolecules consist primarily of carbon and hydrogen
