Effects of pH and Salts on the Aggregation State of Semaglutide and Membrane Filtration Performance

open access: yesSeparations
The hydrophobic region of semaglutide makes it prone to aggregation in aqueous solution, which leads to serious interception in microfiltration. The influences of pH and low concentrations of salts (NaCl, CH3COONa, Na2SO4 and (NH4)2SO4) on the particle ...

Oligoglyceric acid synthesis by autocondensation of glyceroyl thioester [PDF]

open access: yes
The autocondensation of the glyceroyl thioester, S-glyceroyl-ethane-thiol, yielded olioglyceric acid. The rates of autocondensation and hydrolysis of the thioester increased from pH 6.5 to pH 7.5 in 2,6-lutidine and imidazole buffers.
