Amino Acids Found in Proteins • Amino acids contain two functional groups, an amino group (-NH2) and a carboxyl group (-COOH) which are formed on a carboxylic acid. o Alpha amino acids are those where both functional groups are attached to the same carbon. o Side chain/R group and hydrogen atom are also attached to alpha carbon.  Side chain determines the properties of amino acids and its functions. Terminology • There are a variety of different types of amino acids, however the MCA...

This summary sheet provides a detailed revision of Polymers, Amino Acids and Amides from Module 6 of the OCR A-Level Chemistry textbook, although the material is applicable to any exam board. There are key definitions, diagrams and tables followed by detailed explanations of the reactions of the amine group and the carboxylic acid group. This revision sheet covers chirality, naming amides, the formation of polyesters & polyamides and revision of condensation polymerisation. I'd recommend ...

Amino acids are the monomers from which proteins are made. The general structure of an amino acid as: where NH2 represents an amine group, COOH represents a carboxyl group and R represents a side chain. The twenty amino acids that are common in all organisms differ only in their side group. A condensation reaction between two amino acids forms a peptide bond. Dipeptides are formed by the condensation of two amino acids. Polypeptides are formed by the condensation of many amino acids....
