  2. Amino acid - Wikipedia

    en.wikipedia.org/wiki/Amino_acid

    As both the amine and carboxylic acid groups of amino acids can react to form amide bonds, one amino acid molecule can react with another and become joined through an amide linkage. This polymerization of amino acids is what creates proteins. This condensation reaction yields the newly formed peptide bond and a molecule of water.

  3. DNA and RNA codon tables - Wikipedia

    en.wikipedia.org/wiki/DNA_and_RNA_codon_tables

    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.

  4. Protein primary structure - Wikipedia

    en.wikipedia.org/wiki/Protein_primary_structure

    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 ...

  5. Protein - Wikipedia

    en.wikipedia.org/wiki/Protein

    The side chains of the standard amino acids, detailed in the list of standard amino acids, have a great variety of chemical structures and properties; it is the combined effect of all of the amino acid side chains in a protein that ultimately determines its three-dimensional structure and its chemical reactivity. [29]

  6. Tryptophan - Wikipedia

    en.wikipedia.org/wiki/Tryptophan

    Like other amino acids, tryptophan is a zwitterion at physiological pH where the amino group is protonated (– NH + 3; pK a = 9.39) and the carboxylic acid is deprotonated ( –COO −; pK a = 2.38). [5] Humans and many animals cannot synthesize tryptophan: they need to obtain it through their diet, making it an essential amino acid.

  9. Proteinogenic amino acid - Wikipedia

    en.wikipedia.org/wiki/Proteinogenic_amino_acid

    The table below lists the abundance of amino acids in E.coli cells and the metabolic cost (ATP) for synthesis of the amino acids. Negative numbers indicate the metabolic processes are energy favorable and do not cost net ATP of the cell. [12] The abundance of amino acids includes amino acids in free form and in polymerization form (proteins).
