Studies have been carried on with the aim of investigating the effect of SH-groups on the absorption of 35S-thiamine in chicken's duodenum. The trial has been performed in chickens aged 56 days; as SH-groups releasing agents L-cysteine and SH-glutathion have been utilized; urea has been used in order to release SH-groups from protein molecules. The absorption of 35S-thiamine in duodenum is significantly increased in the presence of L-cysteine, SH-glutathion and urea. 35S-thiamine appears to be stored in the intestinal mucosa more conspicuously in the presence of urea. Concomitanly with the high levels of SH-groups in the duodenal mucosa, also the thiamine absorption results to be increased (P less than 0.001).
已开展多项研究，旨在探究巯基对鸡十二指肠中35S -硫胺素吸收的影响。试验在56日龄的鸡身上进行；使用了作为巯基释放剂的L -半胱氨酸和巯基谷胱甘肽；还使用了尿素以从蛋白质分子中释放巯基。在L -半胱氨酸、巯基谷胱甘肽和尿素存在的情况下，十二指肠中35S -硫胺素的吸收显著增加。在尿素存在的情况下，35S -硫胺素似乎更明显地储存在肠黏膜中。随着十二指肠黏膜中巯基水平的升高，硫胺素的吸收结果也会增加（P小于0.001）。
