Intercalation of dipeptides during V2O5.nH2O xerogel condensation
摘要:
(dipeptide)(x)V2O5. 1.0H(2)O (0.27 < x < 0.37) precipitates have been synthesized by adding dipeptides (Val-Gln, Ala-Gln, Gly Gln, Gly Glu and Ala-Gly) to a metavanadate solution acidified using a proton exchange resin. As evidenced by X-ray diffraction, these vanadium oxides exhibit the layered structure of the V2O5.1.8H(2)O xerogels in which dipeptides are intercalated between the layers. These precipitates result from the assembly of ribbon like particles into a sponge like morphology as evidenced by scanning electron microscopy. The vanadium oxide phases were also characterized by V-51 MAS NMR while C-13 CP MAS NMR allowed to investigate the dipeptide preservation during the synthesis. (c) 2006 Elsevier Ltd.

sulfide has been shown to generate short peptides via the formation of cyclic aminoacid N-carboxyanhydrides (NCAs). Here, we show that the polymerization of valine-NCA in the presence of fatty acids yields acylated aminoacids and peptides via a mixed anhydride intermediate. Notably, Nα-oleoylarginine, a product of the reaction between arginine and oleic acid in the presence of valine-NCA, partitions
Tic disorders can be improved by administering theanine, an amino acid that crosses the blood-brain barrier, or a dipeptide consisting of theanine and a different amino acid. In addition, these compositions can be added to foods and drinks or pharmaceuticals.

The present invention provides a method for producing dipeptide using inexpensively acquirable starting materials by an industrially advantageous and simple pathway. Dipeptide is produced from L-amino acid ester and L-amino acid using a culture of microbes having the ability to produce a dipeptide from an L-amino acid ester and an L-amino acid, using microbial cells isolated from the culture, or a treated microbial cell product of the microbe.
