dipeptides การใช้

• Amino acids can also form dimers, which are called dipeptides.
• Dipeptides activate G-cells found in the stomach to secrete gastrin.
• Prolidase serve to hydrolyze both dietary and endogenous Xaa-Pro dipeptides.
• Dipeptides are produced from polypeptides by the action of the hydrolase enzyme dipeptidyl peptidase.
• Pseudoproline dipeptides can be introduced in the same manner as other amino acid derivatives.
• The Bergmann azlactone peptide synthesis is a classic organic synthesis for the preparation of dipeptides.
• Pseudoproline dipeptides have greatly increased the success rate for synthesizing both long and difficult peptides.
• Another powerful strategy for expediting the assembly of complex peptides is to employ pseudoproline dipeptides.
• The method combines the advantages of the PEG-based ChemMatrix resin and pseudoproline dipeptides.
• Also acts on Glu ! Trp, Leu ! Trp and a number of other dipeptides
• :Hydrolysis of unblocked, C-terminal dipeptides from oligopeptides, with broad specificity.
• Nitrogen and carbon are mobilized from cyanophycin by intracellular cyanophycinase in the form of aspartate-arginine dipeptides.
• Other peptides that assume alpha-sheet structures include capped diphenyl-glycine-based dipeptides and tripeptides.
• Along with prolinase, prolidase are the only known enzymes that can break down dipeptides to yield free proline.
• Additionally, it also participates in the process of recycling proline from Xaa-Pro dipeptides for collagen resynthesis.
• The main body of aspein is occupied by ( Asp ) 2 10 sequences punctuated with Ser Gly dipeptides.
• Most dipeptides are not sweet, but the unexpected discovery of aspartame in 1965 led to a search for similar compounds that shared its sweetness.
• Xaa-Pro dipeptidase is a cytosolic dipeptidase that hydrolyzes dipeptides with proline or hydroxyproline at the carboxy terminus ( but not Pro-Pro ).
• Under the tutelage of fellow Bergmann lab researcher Leonidas Zervas, a pioneer in peptide synthesis, Fruton synthesized stereospecific dipeptides and other small peptides as enzyme substrates.
• Dietary proteins are digested to dipeptides and amino acids, and the dipeptides are absorbed more rapidly than the amino acids, because their uptake involves a separate mechanism.
