Important biomolecules

1. Lipids

   • :energy-rich fuel stores, pigment, intracellular signals -monomer: fatty acids-oligomer: phospholipids-supramolecular structure: membranelipidome= the lipid-containing molecules in a cell

2. Proteins

   • :can function as enzymes, structural elements, signal receptors, transporters -monomer: amino acids-polymer: protein subunits-supramolecular structure: protein complexproteome= sum of all the proteins functioning in a cell

3. Carbohydrates

   • :energy-rich fuel stores, rigid structural elements, extracellular recognition elements -monomers: glucose-polymers: cellulose-supramolecular structure: cell wall

4. Nucleic acid

   • : store and transmit genetic information, structural and catalytic roles -monomer: nucleotide -polymer: DNA -supramolecular structure: chromatin
