Ionization and Brønsted character of N-terminal amino, C-terminal carboxylate, and side chains of amino acid residues. The common natural forms of amino acids have a zwitterionic structure, with −NH + 3 (−NH + 2 − in the case of proline) and −CO − 2 functional groups attached to the same C atom, and are thus α-amino acids, and are ...

The first table—the standard table—can be used to translate nucleotide triplets into the corresponding amino acid or appropriate signal if it is a start or stop codon. The second table, appropriately called the inverse, does the opposite: it can be used to deduce a possible triplet code if the amino acid is known.
An essential amino acid, or indispensable amino acid, is an amino acid that cannot be synthesized from scratch by the organism fast enough to supply its demand, and must therefore come from the diet. Of the 21 amino acids common to all life forms, the nine amino acids humans cannot synthesize are valine , isoleucine , leucine , methionine ...
Protein sequence is typically notated as a string of letters, listing the amino acids starting at the amino-terminal end through to the carboxyl-terminal end. Either a three letter code or single letter code can be used to represent the 22 naturally encoded amino acids, as well as mixtures or ambiguous amino acids (similar to nucleic acid ...

During translation, amino acids are joined into a linear chain by condensation reactions which create peptide bonds between the carboxyl group of one amino acid and the amino group of an adjacent amino acid. The first and last amino acids in the chain are said to be N-terminal and C-terminal, respectively, in reference to the unbonded amino ...
An amino acid is any molecule that contains both amino and carboxylic acid functional groups. Subcategories. This category has the following 18 subcategories, out of ...
