The amine group (NH2) and the carboxyl group (COOH-) are the fundamental components of amino acids. They regulate several essential physiological functions of organisms and are found in all forms of life, including humans, plants, and microorganisms. Furthermore, they serve as vital energy sources and also act as neurotransmitters. An analysis of the kidneys of Pterocles alchata, an Iraqi Pin-tailed sandgrouse, revealed the presence of 18 specific amino acids. The data indicate that there were no significant differences in the total amounts of amino acids among the three renal lobes. The concentrations in the anterior, middle, and posterior lobes were measured to be 14.154 ą97. 273, 12.437 ą87. 255, and 11.882 ą88. 157 correspondingly, with a significance level of p≤ 0.05. There were considerable variations in the amounts of amino acids among different areas of the kidney. A glutamine, serine, and asparagine surplus was most pronounced in the kidney lobes. Glutamate proportions were 14.38 ą226. 661 in the back lobe, 22.9 ą231. 929 in the middle lobe, and 27.74 ą261. 852 in the front lobe. The statistical significance of these changes was determined using a significance level of p≤ 0.05.. Applying a probability threshold of p≤ 0.01, the serine concentrations in the kidney lobes were measured as 29.59 ą226. 65, 17.74 ą202. 183, and 7.71 ą199. 840 in the anterior, middle, and posterior lobes, respectively. The concentration of the amino acid asparagine (Asn) in the anterior lobe was 12.61 ą153. 952, in the middle lobe it was 7.47 ą135. 278, and in the posterior lobe it was 10.23 ą128. 885. These concentrations were observed at a …
Keratinases are enzymes belonging to the serine hydrolases group which are capable of degradation of keratin, an insoluble and fibrous structural protein widely cross-linked with hydrogen, disulfide, and hydrophobic bonds. Attempts to find new sources of enzymes and amino acids for fundamental knowledge of enzyme evolution, structure‐function relationships, catalysis mechanisms of enzymes, and even for the identification of novel protein folds. In this study, seventy-nine samples were collected from different places in the University of Baghdad, and the best isolate for amino acid production by feathers degradation was by using Streptomyces venezuelae AZ15. The best fermentation system and the optimum culture condit

The synthesis of 2-[[(Saminosulfinim-idoyl)(aryl)methyl](benzoyl)amino]-5-aryl-1,3-thiazole-4-carboxylic acid (A22-A30) was perfomed starting from (A1-A3) by two steps using Schiff's base (A4-A12) prepared from the reactant compounds (A1-A3) with different aromatic aldehyde. Finally two types of imide derivatives were obtained from reactant compounds (A1-A3) with malic anhydride (A31-A33) and phthalic anhydride (A34-A36) in the presence of glacial acetic acid. All proposed structures were supported by FT-IR and UV-Visible spectroscopic data.
In this research various of 2,5-disubstituted 1,3,4-oxadiazole (Schiff base, oxo-thiazolidine , and other compounds) were synthesized from 2,5-di(4,4?- amino-1,3,4-oxadiazole ) which use quently synthesized from mixture of 4-amino benzoic acid and hydrazine in the presence of polyphosphorus acid. The synthesized compounds were characterized by using some Spectral data (UV, FT-IR, and 1H-NMR).
The scholastic view of public religion differed, and this difference was on two extremes. All economic schools agreed that public debt is a monetary liquidity that was unjustly deducted from the income and output cycle as a result of the imbalance in the economic balance and the departure from the conditions of balance between aggregate demand and aggregate supply. Debt is a waste of financial resources allocated to productive accumulation. Except for the Keynesian school, which considers public debt to be an addition to aggregate demand after the decline in the role of the private sector in investment as a result of pessimistic expectations that warn of signs of economic contraction. Public debt is linked to the ex

renal function is well known. The aim of this study is to
know which group of patients with acute stroke is more
likely to have undiagnosed Chronic Kidney Disease and
which risk factors are more likely to be associated with.
Methods:We studied 77 patients who were diagnosed to
have an acute stroke.Patients were selected between
April2011andJune 2011 using the " 4-variable
Modification of
Diet in Renal Disease Formula " which estimates
Glomerular Filtration Rate using four variables :serum
creatinine ,age ,race and gender.
Results :The study included 38 male and 39 females
patients ,aged (35-95) years. Glomerular Filtration Rate in
patients wi
Acid dissociation constants of some Schiff bases derived from 4, 6-dimethyl 2-amino pyrimidine of the type (1) in 50% V/V dioxane-water mixture in 0.003M KCl, at three different temperatures were determined potentiometrically. The thermodynamic energies were calculated and a good linear correlation was obtained between pKa and IR OH. Stretching frequencies.
In this study a new ligand ,(potassium 2-carbomethoxy amino-5-trithiocarbonate 1,3,4-thiadiazole) (L) has been prepared from 2-carbomethoxy amino-5-mercapto 1,3,4-thiadiazole with CS2 in alkali media . The product has been isolated and characterized by appropriate physical measurements, vibrational and electronic spectroscopy. The ligand was used to prepare a number of complexes with some metal ions Co(II), Ni(II) and Cu(II). These complexes have been characterized by FT-IR, UV-Vis spectra, molar conductivity, magnetic susceptibility, melting points and atomic absorption measurements. The nickel and copper complexes have an octahedral geometry while cobalt complex has a tetrahedral geometry. The nature of bonding between the metal ion
