Electrochemical Oxidative Decomposition of Aliphatic Amino Acids.

Charge-Transfer Interactions of Aliphatic Amino Acids with Metal Ions

The effect of various non-SH-containing amino acids on an electron spin resonance spectrum as well as on an optical absorption spectrum of an aqueous copper (II) solution was investigated. The data obtained indicate that a charge-transfer complex is formed with amino acids acting as electron donors. A plot of the wavelength of the CT-band vs. the pK values of the carboxyl group exhibits a strai...

Removal of Cysteine (an Aliphatic Amino Acid) by Natural Clinoptilolite

Amino acids have been extensively used in several processes of the pharmaceutical and food industries. Treatments for the recovery and reuse of the wastewaters generated from these processes are few and little known. This work aims at studying the influence of different variables on the sorption of L-cysteine, contained in aqueous solutions, on clinoptilolite mineral. L-Cysteine (Cys) was s...

Effects of aliphatic fatty acids

octanoate or decanoate per mol of albumin caused a decrease in dye binding (dye/protein molar ratio 1 : 1), which, in contrast with additional fatty acid, was very pronounced: 1-8mol of palmitate or stearate resulted in a small, and apparently linear, displacement of Phenol Red. The displacement effect of 1-5 mol of oleate, linoleate or linolenate per mol of albumin was comparable with that of ...

Carbon 13 nuclear magnetic resonance of pentapeptides of glycine containing central residues of aliphatic amino acids.

Pentapeptides containing either glycine, L-alanine, Lvaline, L-leucine, or L-isoleucine as central residue in the pattern glycylglycyl-X-glycylglycine have been studied by proton-decoupled natural abundance W Fourier transform nuclear magnetic resonance spectroscopy. Resonances were assigned by comparison with the free amino acids and by detailed observation of changes in chemical shifts with p...
