Dipeptides

d-Ala-Gln is adipeptide.

Ala-d-Gln is adipeptide.

H-Trp-Tyr-OH is an orally active tryptophan-tyrosine dipeptide with blood-brain barrier permeability. H-Trp-Tyr-OH exerts physiological regulatory effects by stimulating enteroendocrine cells to secrete glucagon-like peptide GLP-1. In mouse models of tauopathies, H-Trp-Tyr-OH inhibits tau phosphorylation, reduces the level of neurofibrillary tangles, increases dopamine turnover, upregulates synapsin expression, and elevates cecal short-chain fatty acid levels, thereby improving behavioral deficits and extending lifespan. H-Trp-Tyr-OH can be used in research related to impaired glucose tolerance and tauopathies.

H-Pro-Trp-OH is adipeptide.

H-His-Lys-OH is adipeptide.

H-Asp-Ala-OH is adipeptide.

Ala-Ala-OMe is adipeptide derivative.

H-Leu-Trp-OH is adipeptide.

H-Gly-Cys-OH is adipeptide.

Cyclo(-Glu-Glu) is a cyclic peptide, a cyclic structure formed by linking two glutamic acid residues through a peptide bond.

H-His-His-OH is an oligopeptide. H-His-His-OH can chelate with Ruthenium (II). H-His-His-OH inhibits the hydrolysis of metal ions at pH 7.4.

H-Ala-Arg-OH is an L-arginyl dipeptide that can be used as salt taste enhancer.

H-Pro-Met-OH is a dipeptide containing proline and methionine. H-Pro-Met-OH also serves as a substrate for prolinase and prolyl dipeptidase.

Glu-Lys is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

Cyclo(Met-Met) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

Cbz-Tyr-Ala-OH is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

Cyclo(D-Ala-Val) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

Cyclo(D-His-Pro) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

Tri-valine (NSC 35938) is a polypeptide that can be separated from Creatine kinase (HY-P2799), β-enolase, Triosephosphate isomerase (HY-P2931) and glyceraldehyde 3-phosphate dehydrogenase.

Di-aspartic acid (Aspartylaspartate) can be utilized as growth substrate for P. gingivalis, P. intermedia, P. nigrescens and F. nucleatum.
