Abstract
Effects of thiamin triphosphate (TTP) on contraction of chemically skinned fibers prepared from the extensor digitorum longus muscle of guinea pigs were investigated. The addition of TTP at 40 microM concentration affected neither Ca2+ uptake nor Ca(2+)-induced Ca2+ release by sarcoplasmic reticulum. Contraction of myofibril was not affected by TTP either.
摘要
研究了三磷酸硫胺素（TTP）对豚鼠趾长伸肌制备的化学去皮纤维收缩的影响。添加浓度为40微摩尔的TTP对肌浆网的钙离子摄取或钙离子诱导的钙离子释放均无影响。TTP对肌原纤维的收缩也没有影响。
