  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 ...

  4. 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. Protein structure - Wikipedia

    en.wikipedia.org/wiki/Protein_structure

    Protein structure is the three-dimensional arrangement of atoms in an amino acid-chain molecule. Proteins are polymers – specifically polypeptides – formed from sequences of amino acids, which are the monomers of the polymer. A single amino acid monomer may also be called a residue, which indicates a

    en.wikipedia.org/wiki/Phenylalanine

    Phenylalanine ball and stick model spinning. Phenylalanine (symbol Phe or F) [3] is an essential α-amino acid with the formula C 9 H 11 NO 2.It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine.

  9. Amino acid synthesis - Wikipedia

    en.wikipedia.org/wiki/Amino_acid_synthesis

    Amino acid biosynthesis overview. The drawn molecules are in their neutral forms and do not fully correspond to their presented names. Humans can not synthesize all of these amino acids. Amino acid biosynthesis is the set of biochemical processes (metabolic pathways) by which the amino acids are produced.
