In solution the C5 –OH of open-chain glucose adds to the C1 aldehyde, closing a six-membered pyranose ring.
Ring closure makes C1 a new stereocentre: with its –OH down (Haworth) it is α-D-glucose, up it is β-D-glucose.
Two monosaccharides join by a glycosidic bond, losing water: two α-glucose units linked C1–O–C4 make maltose.
Amino acids join when the –COOH of one and the –NH₂ of the next lose water, forming a peptide bond –CO–NH–.
The sequence of amino acids is the primary structure; the chain coils into an α-helix held by hydrogen bonds.
Nucleotides (base + deoxyribose + phosphate) pair across DNA strands: A with T by two H-bonds, G with C by three.
The two DNA strands run in opposite directions (antiparallel) and each base pair is one purine with one pyrimidine.
Hydrolysis reverses condensation: water splits glycosidic and peptide bonds, as enzymes do during digestion.
