Biomolecules = Chemicals of living organisms - 2 types: Micro (small, soluble) - monosaccharides, amino
acids, nucleotides, fatty acids and Macro (large, insoluble) - proteins, polysaccharides, nucleic acids, lipids
Analysis: Grind tissue with CCl3COOH trichloroacetic acid - filtrate = soluble small biomolecules
(micromolecules), retentate = insoluble large (macromolecules)
Live analysis: C H O N present in living, Ash analysis: Inorganic elements - Na K Ca Mg etc remain after
burning
Water = Most abundant 70-90% of cell weight, proteins next 10-15%, lipids 2%, nucleic acids 5-7%, carbs
