THE EXAMS POINTFrom building blocks to biological polymers
Begin at the centre. Explore a branch, explain its connection, then test your recall. Tap any branch heading to fold or expand it.
In recall mode, focus or tap a branch to reveal its explanation. Branches group related ideas; they do not imply a chronological sequence.
From building blocks to biological polymers
01 · Proteins
Amino acids join through peptide bonds; folding helps determine function.
02 · Nucleic acids
Nucleotides form DNA and RNA.
03 · Polysaccharides
Monosaccharides join through glycosidic linkages.
04 · Lipids
A diverse group; they are not generally repeating-monomer polymers in the same way.
Connect the branches
Structure and bonding explain biological function.
Avoid the exam trap
Not every biological macromolecule is a polymer built from a repeating monomer.
Test yourself: What bond joins amino acids in a polypeptide?
A peptide bond joins the amino and carboxyl groups of successive amino acids.
A concise revision aid with simplified connections. It supports the full chapter and primary references; it does not replace them.
