Abstract In this work, we report a flexible nanofibrous cellulose nanocomposite with great potential for lithium-ion battery (LiB) polymer electrolyte. Flexible and fibrous material is synthesized using simple easy technique by synergistically combining carboxymethyl (CMC) glycerol (Gly). porous forms three-dimensional network the mobility of Li ions in electrolyte LIB systems. We investigated ...

To assess the digestion and assimilation of gelatin and gelatin hydrolysates, the in situ absorption of typical hydroxyproline-containing dipeptides, Pro-Hyp, Hyp-Gly, Ser-Hyp Ala-Hyp, and pentadecapeptide, (Pro-Hyp-Gly)(5), was investigated in the rat small intestine. During vascular perfusion after the injection of Hyp-Gly, Pro-Hyp and (Pro-Hyp-Gly)(5) into the jejunum, peptide-form Hyp but n...

Glycine allele at codon 16 has previously been associated with the increase in asthma severity, bronchial hyperresponsiveness and also the increase in inhaled corticosteroid dependence. This study was designed to evaluate the genetic alleles in mild asthma.Thirty-four patients with diagnosis of mild asthma (FEV1 ≥ 80%, positive methacholine test) and body mass index (BMI ≤ 30 Kg/m2) were includ...

Valorization of glycerol (Gly) to high-value chemicals is the key unlocking economic and sustainable biodiesel production.

In this study the roles of invariant Asn-247, Asp-282, Gly-284, Gly-286 and Gly-319 of pyruvate dehydrogenase kinase were investigated by site-directed mutagenesis. Recombinant kinases, wild-type, Asn-247Ala, Asp-282Ala, Gly-284Ala, Gly-286Ala and Gly-319Ala, were expressed in bacteria, purified, and characterized. Three mutant kinases, Asn-247Ala, Asp-282Ala and Gly-286Ala, lacked any apprecia...

A short sequence motif rich in glycine residues, Gly-X-X-X-X-Gly-Lys-Thr/Ser, has been found in many nucleotide-binding proteins including the beta subunit of Escherichia coli H(+)-ATPase (Gly-Gly-Ala-Gly-Val-Gly-Lys-Thr, residues 149-156). The following mutations were introduced in this region of the cloned E. coli unc operon carried by a plasmid pBWU1: Ala-151----Pro or Val; insertion of a Gl...

Hydroxylation of proline residues in the Yaa position of the Gly-Xaa-Yaa repeated sequence to 4(R)-hydroxyproline is essential for the formation of the collagen triple helix. A small number of 3(S)-hydroxyproline residues are present in most collagens in the Xaa position. Neither the structural nor a biological role is known for 3(S)-hydroxyproline. To characterize the structural role of 3(S)-h...

Amino acid sequences of three canine bombesin-like peptides were determined after sequential purification of an extract obtained from 820 g of intestinal muscle. These three peptides contained 27, 23, and 10 amino acid residues. The sequences of the two shorter forms were identical to the corresponding carboxyl-terminal sequence of the heptacosapeptide. The sequence of the largest peptide is H2...

Radiolabeled bombesin analogs are promising probes for cancer imaging of gastrin-releasing peptide receptor (GRPR). In this study, we developed (18)F-labeled GRPR agonists and antagonists for positron emission tomography (PET) imaging of prostate cancer. GRPR antagonists ATBBN (D-Phe-Gln-Trp-Ala-Val-Gly-His-Leu-NHCH(2)CH(3)) and MATBBN (Gly-Gly-Gly-Arg-Asp-Asn-D-Phe-Gln-Trp-Ala-Val-Gly-His-Leu-...
