Thermodynamics of Methylamine and Ammonia Synergy in Copper-Catalyzed Thiosulfate Gold Leaching

Metals
Thiosulfate leaching is considered a promising alternative to cyanidation for gold extraction because it can be achieved at a low cost. However, existing leaching systems struggle to balance leaching efficiency with thiosulfate consumption.

C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

Chemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Testing the ability of non-methylamine osmolytes present in kidney cells to counteract the deleterious effects of urea on structure, stability and function of proteins. [PDF]

PLoS ONE, 2013
Human kidney cells are under constant urea stress due to its urine concentrating mechanism. It is believed that the deleterious effect of urea is counteracted by methylamine osmolytes (glycine betaine and glycerophosphocholine) present in kidney cells. A

Methylamine clearance by haemodialysis is low [PDF]

Nephrology Dialysis Transplantation, 2009
Dialysis adequacy is currently judged by measures of urea clearance. However, urea is relatively non-toxic and has properties distinct from large classes of other retained solutes. In particular, intracellularly sequestered solutes are likely to behave differently than urea.We studied an example of this class, the aliphatic amine monomethylamine (MMA),
