This experiment was designed to investigate the effects of different levels copper–methionine chelates and alfalfa powder on egg yolk cholesterol content, quality, performance in laying hens. In this experiment, a total 100 hens (Nick Chick strain, from 109 117 weeks age) were arranged into five experimental treatments, consisting 2 dietary copper chelate (2x2) factorial completely randomized d...

the objective of this study was to evaluate the effects of supplementation of different level protein diets with rumen protected methionine and lysine on performance and ruminal parameters in holstein dairy cows when in their early lactation. twenty one dairy cows in their early lactations were assigned to three treatments in a randomized block design experiment of a 35-d duration period. diets...

Two separate studies were conducted using a continuous culture fermenter system to determine effects of supplementing D,L-methionine and various methionine derivatives on degradation of methionine by ruminal bacteria. A basal diet containing 20% alfalfa hay, 20% corn silage and 60% grain mix (DM basis) was provided at a rate of 75 g DM/d per fermenter and served as an unsupplemented control in ...

Methionine sulfoxide reductase A (MsrA) catalyzes the reduction of methionine sulfoxide to methionine and is specific for the S epimer of methionine sulfoxide. The enzyme participates in defense against oxidative stresses by reducing methionine sulfoxide residues in proteins back to methionine. Because oxidation of methionine residues is reversible, this covalent modification could also functio...

In this article, monkeypox is studied as a zoonotic poxvirus disease which can occur in humans and other animals due to substitution of the amino acid serine with methionine. We investigate (+)-catechin, betulinic acid, ursolic quercetin-3-O-galactoside, luteolin-7-O-glucoside, myricetin Sarracenia purpurea drugs from Sarraceniaceae family for treating disease. This performed via adsorption ont...

The endotelio- and cardioprotective effects of vitamin B6 (2 mg/kg) folic acid (0.2 upon modeling methionine-induced hyperhomocysteinemia via methionine intragastric administration at a dose 3 g/kg were studied. It was shown that the combined use allows on background significant reduction in homocysteine concentrations normalizing endothelial dysfunction coefficient parameters maximum left vent...

Methionine is an amino acid that extremely important for human health. To better understand the biochemical events occurring in body, excess molar properties of methionine and aqueous ethanol methanol mixtures were determined at 298.15 K. Interactions between components solutions are explained. Negative deviations from ideal state have been observed due to hydrogen bonds, dipole interactions, c...
