  2. Amino acid - Wikipedia

    en.wikipedia.org/wiki/Amino_acid

    Structure of a typical L-alpha-amino acid in the "neutral" form. Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1] Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. [2] Only these 22 appear in the genetic code of life ...

  6. Protein primary structure - Wikipedia

    en.wikipedia.org/wiki/Protein_primary_structure

    Protein primary structure is the linear sequence of amino acids in a peptide or protein. [1] By convention, the primary structure of a protein is reported starting from the amino -terminal (N) end to the carboxyl -terminal (C) end.

  7. Hydrophobicity scales - Wikipedia

    en.wikipedia.org/wiki/Hydrophobicity_scales

    The first and third scales are derived from the physiochemical properties of the amino acid side chains. These scales result mainly from inspection of the amino acid structures. [14] [1] Biswas et al., divided the scales based on the method used to obtain the scale into five different categories. [3]

  8. Aromatic amino acid - Wikipedia

    en.wikipedia.org/wiki/Aromatic_amino_acid

    Aromatic amino acids, excepting histidine, absorb ultraviolet light above and beyond 250 nm and will fluoresce under these conditions. This characteristic is used in quantitative analysis, notably in determining the concentrations of these amino acids in solution. [1] [2] Most proteins absorb at 280 nm due to the presence of tyrosine and ...
