Biomolecules and chemical structure · Revision sheet
Connect monomers and linkages without saying all biological molecules are polymers.
Learn the idea
Carbohydrates
Sugars can join through glycosidic links; structure matters for function.
Proteins
Amino-acid residues form chains with peptide, or amide, linkages.
Nucleic acids
Nucleotides form nucleic-acid chains containing a sugar-phosphate backbone and bases.
Lipids
Lipids are a diverse group and are not all repeating-monomer polymers.
Explain without looking
- Why is identifying one functional group insufficient to predict every biomolecule's behavior?
- Which statement is accurate?
