Structure and Reactions of Amino Acids
Structure and Reactions of Amino Acids
An α\alphaα-amino acid is a bifunctional compound containing both a basic amine group (-NH2\text{-NH}_2-NH2) and an acidic carboxylic acid group (-COOH\text{-COOH}-COOH) attached to the same central carbon atom (the α\alphaα-carbon).
Because they possess both acidic and basic functional groups within a single molecule, amino acids are amphoteric and can undergo reactions characteristic of both groups.
Step-by-step lessons on OCR A A Level Chemistry Amino acids, amides and chirality. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
