The ability to accurately qualify and quantify amino acids at a molecular level is essential to your work, but consistently obtaining reliable data can pose significant challenges. Biochrom’s 30+ series of amino acid analyzers deliver gold-standard performance and accuracy, as well as industry-leadi...
Amino acids and glucose cooperate in the regulation of Pdx1 protein stability in a Rab1A-dependent manner (Figure 5J). Consistently, immunoblot and IHC analysis showed considerably reduced Pdx1 protein level in Rab1A−/− islets compared with Rab1A+/+ pancreas (Figure 5K). In fact, the ...
Proteins (from Greek ‘prota,’ which means ‘of primary importance’) are polymers that are composed of many amino acids joined together, as a linear chain, by amide bonds. From: Encyclopedia of Food and Health, 2016 About this pageSet alert ...
Metal-catalysed reactions involving ammonia gas are plagued by ammonia’s strong Lewis basicity, which leads to poor chemoselectivity and enantioselectivity. Here we introduce a strategy for preparing chiral α-amino acids directly from ammonia. By the c
Amino acids are the building blocks of protein synthesis. They are structural elements and energy sources of cells necessary for normal cell growth, differentiation and function. Amino acid metabolism disorders have been linked with a number of pathologi
Reactivity ProfileAmino-2-propanol is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amin...
Although, proline has been vastly studied for its role as a compatible solute in mitigating abiotic stress effects in plants, other amino acids (both proteinogenic and nonproteinogenic) have received considerably less attention in this context. This chapter provides the current state of knowledge ...
The ionic complexes formed by electrospray of methanol/water solutions of all the α amino acids (AA) were studied by collisional activation in a triple qu... Franoise,Rogalewicz,and,... - 《International Journal of Mass Spectrometry》 被引量: 224发表: 2000年 N-C[sub alpha] Bond Dissociat...
Here, we have analyzed the quantum chemistry of all proteinogenic and various prebiotic amino acids. We find that the energetic HOMO–LUMO gap, a correlate of chemical reactivity, becomes incrementally closer in modern amino acids, reaching the level of specialized redox cofactors in the late ...
