  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.

  3. Oligopeptide - Wikipedia

    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. 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. Proteinogenic amino acid - Wikipedia

    en.wikipedia.org/wiki/Proteinogenic_amino_acid

    Essential for humans, phenylalanine, tyrosine, and tryptophan contain a large, rigid aromatic group on the side chain. These are the biggest amino acids. Like isoleucine, leucine, and valine, these are hydrophobic and tend to orient towards the interior of the folded protein molecule. Phenylalanine can be converted into tyrosine. Glycine: G Gly

  7. Branched-chain alpha-keto acid dehydrogenase complex

    In animal tissue, BCKDC catalyzes an irreversible step [2] in the catabolism of the branched-chain amino acids L-isoleucine, L-valine, and L-leucine, acting on their deaminated derivatives (L-alpha-keto-beta-methylvalerate, alpha-ketoisovalerate, and alpha-ketoisocaproate, respectively) and converting them [3] to α-Methylbutyryl-CoA, Isobutyryl-CoA and Isovaleryl-CoA respectively.

    en.wikipedia.org/wiki/Biomimetic_material

    Its primary functional site for bioactivity is its core protein domain isoleucine-lysine-valine-alanine-valine (IKVAV), which is located in the α-1 chain of laminin. [14] A recent study by Wu, Zheng et al., synthesized a self-assembled IKVAV peptide nanofiber and tested its effect on the adhesion of neuron-like pc12 cells. Early cell adhesion ...

  9. Human skin - Wikipedia

    en.wikipedia.org/wiki/Human_skin

    The actual skin colour of different humans is affected by many substances, although the single most important substance determining human skin colour is the pigment melanin. Melanin is produced within the skin in cells called melanocytes and it is the main determinant of the skin colour of darker-skinned humans.
