The observed species in N-acetyl-L-arginine and Nα -carbamyl-L-arginine were attributed to the CH2CHNHCNHNH2 radical, and those in N-glycyl-L-leucine and glycyl-L-alanine powders to (CH3)2CCH2 and CH3CHCOOH radicals.

Abstract Background: Glycohemoglobin (gHb), measured as hemoglobin (Hb) A1c or as total gHb, provides a common means for assessing long-term glycemic control in individuals with diabetes mellitus. Genetic variants and chemically modified derivatives of Hb can profoundly affect the accuracy of these measurements, although effects vary considerably among commercially available methods. The prevalence of genetic variants such as HbS, HbC, and HbE, and chemically modified derivatives such as carbamyl-Hb among patient populations undergoing testing is not insignificant.

ABSTRACT dl-2-amino-Δ2-thiazolin-4-carbonic acid (dl-ATC) is a substrate for cysteine synthesis in some bacteria, and this bioconversion has been utilized for cysteine production in industry. We cloned a DNA fragment containing the genes involved in the conversion of l-ATC to l-cysteine from Pseudomonas sp. strain BS. The introduction of this DNA fragment into Escherichia coli cells enabled them to convert l-ATC to cysteine via N-carbamyl-l-cysteine (l-NCC) as an intermediate. The smallest recombinant plasmid, designated pTK10, contained a 2.6-kb insert DNA fragment that has l-cysteine synthet

Abstract:
Antibiotic resistance is becoming ever more severe due in part to the increasing use of antibiotic drugs. One significant contributor to this problem is the production of β-lactamase enzymes that provide resistance to common β-lactam antibiotics. The scope of this research is to synthesize and study the β-lactamase inhibitors of 2-carbamoyl-4-oxo-1,5-diazabicyclo [3.2.1] octane derivatives. Currently the research process is in the beginning stages of synthesizing three compounds: (R)-hexahydro-6-oxopyrimidine-4-carboxylic acid (1a), hexahydro-2,2-dimethyl-6-oxopyrimidine-4-carboxylic acid (1b)

Disorders of purine and pyrimidine metabolism are due to abnormalities in the biosynthesis, interconversion, and degradation of the purines—adenine and guanine—and of the pyrimidines—cytosine, thymine, and uracil. The purine nucleotides, their cyclic derivatives (cAMP and cGMP), and their more highly phosphorylated derivatives have functions in many aspects of intermediary metabolism. Purine compounds also function as signal transducers, neurotransmitters, vasodilators, and mediators of platelet aggregation.

Abstract:
Abstract Selenocarboxylic acids and their derivatives are the selenium isologues of carboxylic, thioic, carbamic, and carbonic acids, and the corresponding esters, amides, and ureas, and are distinguished by the presence of a C=Se bond. The synthesis of these selenium analogues primarily involves incorporating selenium atoms into precursor molecules. This can be achieved by reducing elemental selenium to produce Se2– species, which are then introduced into electrophilic species. Alternatively, carbon nucleophiles can directly bond with elemental selenium, forming carbon–selenium bonds. Compoun
