Progress and development trend of mercaptoacetic acid synthesis process;

In order to remove both soluble heavy metal species and insoluble substances efficiently by flocculation,a novel water-soluble macromolecule heavy metal flocculant,mercaptoacetyl polyethyleneimine(MAPEI) was synthesized by reacting polyethyleneimine with mercaptoacetic acid.

Synthesis and characterization of Antimony(Ⅲ) ternary complex with thioglycollic acid and INH of antibacterial activity;

The thioglycollic acid(TGA) combined with polyethyleneimine(PEI) was used in water flocculation treatment in order to remove not only Cu(II) but also turbidity.

Five N tetrahydrobenzothiazolyl imines have been synthesized by the condensation of 4,5,6,7 tetrahydro 2 benzothiazolamine with aromatic aldehydes and the reactions of imines respectively, with thioglycollic acid obtained five thiazolidones.

Study on analysis of thioglycolic acid in cosmetics by ion chromatography;

Synthesis of thioglycolic acid by sodium sulfide;

Synthesis and indexes of X-ray powder diffraction data of the complex of thioglycolic acid and trivalent antimonyion;

Cloning and sequence analysis on cDNA of cysteine proteinase inhibitor gene from Populus tomentosa Carr.;

Circular dichroism(CD) spectrum of cysteine proteinase inhibitor(CPI) displayed two negative peaks on 206nm and 222nm, indicating that the main secondary structure of CPI was α-helix.

Two thiol-protease inhibitors (CPI or cysteine proteinase inhibitors) from seeds of wheat (Miannong) were separeted by extraction, fraction with(NHt)2SO4,affinity chromatography on the papain-Sepharose 4B and ion-exchange chromatography on DEAE-Sepharose and gel filtration on Sephadex G-100 column.
