亚麻籽巯基肽的制备及富集Preparation and enrichment of flaxseed sulfhydryl peptide
Zhongguo youzhi, 2022 天然巯基化合物因生理活性高、毒副作用低等优势越来越受到关注。为获得天然巯基肽，以低温压榨亚麻籽饼为原料提取亚麻籽蛋白，进一步酶解制备富含巯基的亚麻籽蛋白酶解物，并采用共价色谱法富集亚麻籽巯基肽。首先对蛋白酶进行了筛选，然后以酶解温度、pH、酶解时间、酶添加量、料液比为考察因素，以巯基含量为评价指标，在单因素实验的基础上通过正交实验对酶解工艺进行优化。采用Thiopropyl Crystarose 6 Fast Flow凝胶对亚麻籽蛋白酶解物中巯基肽进行选择性吸附并洗脱收集 ...

Bactericidal Action of Sulfhydryl Binding Compounds [PDF]
Antimicrobial Agents and Chemotherapy, 1973 An oxidation product of indole-3-acetic acid, 3-methyleneoxindole, is highly reactive with free sulfhydryl groups. It has been shown to be a potent bactericidal agent in actively growing cultures. The bactericidal action of 3-methyleneoxindole was found to be independent of protein or deoxyribonucleic acid synthesis but to require the ...

Sulfhydryl Compounds and Crystalline Urease
Experimental Biology and Medicine, 1933 Perlzweig1 states that both crystalline urease and extracts of jack bean meal give a positive sulfhydryl test with nitroprusside and that the more active preparations give stronger tests than the weaker ones. He estimates one of his samples of jack bean meal to contain the equivalent of 70 mg. of glutathione per 100 gm.
