Periodic Table of Elements
Amino Acids and Peptides Educational Links
Amino acid basics - A well done Flash animation on amino acids, peptide synthesis, and secondary structure
Amino acid overview - A basic reference covering the structure and chemical properties of amino acids. Individual amino acids and other terms are hyper-linked to more in depth descriptions. From Wikipedia, the free online encyclopedia!
Amino acid properties - A good references page describing general properties (e.g., structures and protecting group masses), suggested amino acid substitutions, chemical properties (e.g., chemical classification and hydrophobicity), structural properties (e.g., peptide bond angles and Chou-Fasman parameters), and genetic properties. Original references for all the tables are also provided. From PROWL - a resource for protein chemistry and mass spectrometry.
Nomenclature and Symbolism for Amino Acids and Peptides - From the International Union of Pure and Applied Chemistry and the International Union of Biochemistry and Molecular Biology.
Peptide Societies
American Chemical Society - ACS is not strictly about peptides but many of their conferences and journals contain peptide related research.
American Peptide Society
Australian Peptide Association
British RSC Protein and Peptide Science Group
European Peptide Society
