  2. Valine - Wikipedia

    en.wikipedia.org/wiki/Valine

    Valine (symbol Val or V) [4] is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH 3 + form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a side chain isopropyl group, making it a non-polar aliphatic amino acid.

    en.wikipedia.org/wiki/Oligopeptide

    green marked amino end (L-Valine) and blue marked carboxyl end (L-Alanine) A tetrapeptide (example Val-Gly-Ser-Ala) with green marked amino end (L-valine) and blue marked carboxyl end (L-alanine) An oligopeptide (oligo-, "a few"), is a peptide consisting of two to twenty amino acids, including dipeptides, tripeptides, tetrapeptides, and other ...

  4. 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]

  5. Tripeptide - Wikipedia

    en.wikipedia.org/wiki/Tripeptide

    green marked amino end (L-Valine) and blue marked carboxyl end (L-Alanine) A tripeptide is a peptide derived from three amino acids joined by two or sometimes three peptide bonds. [1] As for proteins, the function of peptides is determined by the constituent amino acids and their sequence.

  6. C-terminus - Wikipedia

    en.wikipedia.org/wiki/C-terminus

    A tetrapeptide (example: Val-Gly-Ser-Ala) with green highlighted N-terminal α-amino acid (example: L-valine) and blue marked C-terminal α-amino acid (example: L-alanine). The C-terminus (also known as the carboxyl-terminus , carboxy-terminus , C-terminal tail , carboxy tail , C-terminal end , or COOH-terminus ) is the end of an amino acid ...

    Interestingly, this was true for healthy adults but not people at high risk of developing cardiovascular disease. Other studies support the anti-inflammatory benefits of red wine consumption.

  9. Peptide - Wikipedia

    en.wikipedia.org/wiki/Peptide

    green marked amino end (L-valine) and blue marked carboxyl end (L-alanine) Peptides and proteins are often described by the number of amino acids in their chain, e.g. a protein with 158 amino acids may be described as a "158 amino-acid-long protein". Peptides of specific shorter lengths are named using IUPAC numerical multiplier prefixes:
