Alpha-amino acids: core structure

Alpha-amino acids: core structure

General structure of an alpha-amino acid with alpha-carbon labelled, zwitterion form, and the main forms in acidic, near neutral, and alkaline solution with overall charges An α\alphaα-amino acid has both the amino group and the carboxyl group attached to the same carbon atom, called the α\alphaα-carbon. Its general formula is H2N−CH(R)−COOHH_2N-CH(R)-COOHH2​N−CH(R)−COOH, where RRR is the side chain that changes from one amino acid to another.

Step-by-step lessons on Eduqas A Level Chemistry Amino acids, peptides and proteins. 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.
