We'll start with a definition, move on to talking about some common acylating reagents, and then discuss a few common acylation reactions in organic chemistry.
vb to introduce one or more acyl groups into a compound Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers Previously it was thought that only the acylated form was active in the process of weight increase, but many studies point to both hormones being biologically functional. Ghrelin hormone increases appetite, favours build up of abdominal fat What does acylated mean? (organic chemistry) Having an acyl functional group. (adjective) Gauna, C. et al. Administration of acylated ghrelin reduces insulin sensitivity, whereas the combination of acylated plus unacylated ghrelin strongly improves insulin sensitivity.

Author information: (1)Department of Biological Chemistry, Faculty of Agriculture, Yamaguchi University, Yamaguchi 753-8515, Japan. Effect of acylated ghrelin concentrations on embryo quality during IVM. TCN per blastocyst (Experiment 7) was higher in the Control compared with any of the acylated ghrelin concentrations tested (P < 0.01; Table 5). Addition of 20, 40 or 60 pM acylated ghrelin decreased TCN per blastocyst in a dose-dependent manner. A method for recovering an acylated protein as a powder, especially in cases where said acylated protein is one that resists isolation by isoelectric precipitation from aqueous solutions of the protein, said method comprising in combination adjusting said aqueous solution to near the isoelectric pH of the protein and providing a suitable alcohol concentration to cause precipitation of the The irreversible degradation of acylated red cabbage anthocyanins at 50 °C leads to several groups of products, among which phloroglucinaldehyde-2-glucoside, p-coumaroylsophorose (a mixture of regioisomers) and derivatives of 2-(3,4-dihydroxy)benzoyloxy-4,6-dihydroxyphenylacetic acid are the major ones. In this study, native pectin (Na-Pe) was acylated with gallic acid through enzymatic method. UV–Vis, Fourier transform infrared spectroscopy and proton NMR analyses demonstrated that the phenolic hydroxyl group on gallic acid attacked the carbomethoxy of Na-Pe and replaced the methoxy group to form a new ester group under catalysis.

This electrophilic aromatic substitution allows the synthesis of monoacylated products from the reaction between arenes and acyl Reversible S-palmitoylation is a key regulatory mechanism of protein function and localization. There is increasing evidence that S-acylation is not restricted to Jun 5, 2019 You have already learned that the carboxylate functional group is a very unreactive substrate for an enzyme-catalyzed acyl substitution reactions.
