  • Amino acid - Building Blocks, Structure, Functions: One of the most useful manners by which to classify the standard (or common) amino acids is based on the polarity (that is, the distribution of electric charge) of the R group (e.g., side chain). Group I amino acids are glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, and tryptophan. The R groups of these amino acids have either aliphatic or aromatic groups. This makes them hydrophobic (“water fearing”). In aqueous solutions, globular proteins will fold into a three-dimensional shape to bury these hydrophobic side chains in the protein interior. The chemical structures of Group I amino acids are: Isoleucine

6. amino acid side chains. part iii

  • Neutral-polar side chains. As can be seen ... There are two sulphur containing amino acids (cysteine and methionine) which are largely non-polar in character.

  • As can be seen below there are a number of small aliphatic side chains containing polar groups which cannot ionise readily. Serine and threonine possess hydroxyl groups in their side chains and as these polar groups are close to the main chain they can form hydrogen bonds with it. This can influence the local conformation of the polypeptide, indeed residues such as serine and asparagine are known to adopt conformations which most other amino acids cannot. The amino acids asparagine and glutamine posses amide groups in their side chains which are usually hydrogen-bonded whenever they occur in the interior of a protein. Here is a pdb-file for RasMol.

  • The proteins in all living species, from bacteria to humans, are constructed from the same set of 20 amino acidsA molecule that contains an amino group and a carboxyl group., so called because each contains an amino group attached to a carboxylic acid. (For more information about amino groups, see Chapter 15 "Organic Acids and Bases and Some of Their Derivatives", Section 15.1 "Functional Groups of the Carboxylic Acids and Their Derivatives".) The amino acids in proteins are α-amino acids, which means the amino group is attached to the α-carbon of the carboxylic acid. (For more information about the α-carbon, see Chapter 15 "Organic Acids and Bases and Some of Their Derivatives", Section 15.2 "Carboxylic Acids: Structures and Names".) Humans can synthesize only about half of the needed amino acids; the remainder must be obtained from the diet and are known as essential amino acidsAn amino acid that must be obtained from the diet because it cannot be synthesized in sufficient quantities by the body..
