Hunt, D. E. (Charles V. Chapin Hospital, Providence, R.I.). Amino acids as protective compounds in ultraviolet-irradiated Hansenula wingei. J. Bacteriol. 88:893-895. 1964.-"Prefeeding" Hansenula wingei with small concentrations of either tryptophan, cystine, tyrosine, phenylalanine, leucine, cysteine, threonine, isoleucine, ethionine, norvaline, or histidine protected this yeast against inactiv...

apolipoprotein a-i is the most abundant protein in cyprinus carpio plasma that plays an important role in lipid transport and protection of the skin by means of its antimicrobial activity. a 527 bp cdna fragment encoding c terminus part of apoa-i from the skin mucosa of common carp was isolated using rt-pcr. after genbank database searching, a partial sequence containing a coding sequence (cds)...

FMOC-Cl is a derivatizing agent widely used both in N-protection reactions of a-amino acids as well quantification and detection amino related molecules using HPLC-PDA or fluorescence analysis. In this work we studied the reaction with gabapentin. However, it was observed that degradation gabapentin-N-FMOC to FMOC-OH occur simultaneously presence basic medium which specific for gabapentin deriv...

Catalytic chemoselective reactions of innately less reactive functionalities over more are described. A cooperative catalyst comprising a soft Lewis acid/hard Brønsted base enabled activation hydroxyl group an amino group, allowing for nucleophilic addition to electron-deficient olefins. The reaction could be applicable variety alcohols, including pharmaceuticals, without requiring tedious prot...

The use of hydrochloric acid in the treatment bottomhole formation zone leads to significant corrosion metals, as well hydrogen and chloride stress cracking pump compressor pipes. In order solve this problem, inhibitors are added a solution. This article presents results study anticorrosive activity number derivatives class 3-alkyl-5-amino-1H-1,2,4-triazole under conditions low-carbon steel. Du...
