Release of free amino acids upon oxidation of peptides and proteins by hydroxyl radicals
Hydroxyl radical-induced oxidation of proteins and peptides can lead to the cleavage of the peptide, leading to a release of fragments. Here, we used high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) and pre-column online ortho-phthalaldehyde (OPA) derivatization-based amino acid analysis by HPLC with diode array detection and fluorescence detection to identify and qu...
متن کاملLocations of amino acids in brain slices from the rat. Tetrodotoxin-sensitive release of amino acids.
1. Amino acids, particularly glutamate, gamma-aminobutyrate, aspartate and glycine, were released from rat brain slices on incubation with protoveratrine (especially in a Ca(2+)-deficient medium) or with ouabain or in the absence of glucose. Release was partially or wholly suppressed by tetrodotoxin. 2. Tetrodotoxin did not affect the release of glutamine under various incubation conditions, no...
متن کاملconjugated linoleic acids, amino acid profile and other characteristics of meat produced under identical condition from two iranian fat tailed breeds of lamb
گوشت قرمز یکی از مهم ترین فرآورده های دامی در تأمین پروتئین و انرژی می باشد که در حمل ویتامین های محلول در چربی نیز حائز اهمیت می باشد. انسان مانند سایر مهره داران اسید های چرب ضروری (لینولئیک و آلفا لینولنیک) مورد نیاز خود از طریق غذا تأمین می نماید. اسید های چرب ضروی پیش ساز اسید های چرب غیر اشباع با چند پیوند دوگانه هستند. اسید لینولنیک پیش ساز اسیدهای چرب امگا 3 و اسید لینولئیک نیز پیش ساز ...
Neuroligand-evoked calcium-dependent release of excitatory amino acids from Schwann cells.
Bradykinin caused a receptor-mediated increase in release of the excitatory amino acids (EAAs) glutamate and aspartate from Schwann cell cultures obtained from dorsal root ganglia (DRG) together with an increase in the cytoplasmic level of free calcium. Perturbations which inhibited brady-kinin-induced calcium mobilization prevented the release of EAAs from glia. The addition of ionomycin cause...
متن کاملRelease of selected amino acids from zinc carriers.
The paper deals with the results of an investigation of the release of selected amino acids (histidine, tryptophan, tyrosine) from model suspensions prepared by co-precipitation with zinc chloride. It has been proven that the influence of the Zn(II)/amino acid molar ratio on dissolution profiles of the tested amino acids and dissolution half-life (t1/2) of histidine or tryptophan is significant...
