Organic Compounds with Functional Groups › BiomoleculesChapter 30The Chemistry of Biomolecules
Sugar, egg white, a vitamin tablet and the DNA in a cell are all made of molecules with a clear structure. We read those structures, follow their reactions and count with them: stereoisomers, rotations, masses and base pairs. The chapter serves the Indian syllabus (NCERT, NEET, JEE Main) and the matching topics of A-Level, IB and AP Chemistry. Python counts the sugar isomers, builds peptides and pairs the bases of DNA.

Carbohydrates: Sugars, Starch and Cellulose
Honey tastes sweet and cotton does not, yet both are built from glucose. We follow the sugars from glucose and fructose to sucrose, starch, cellulose and glycogen: their open and ring forms, their reactions and their optical rotations.
Amino Acids, Peptides, Proteins and Enzymes
An egg turns white when it is boiled, and a drop of enzyme can break down a whole pan of starch. We study the amino acids and their charges, the peptide bond, the levels of protein structure, denaturation, and how an enzyme speeds up a reaction in chemical terms.
