补充资料:限流安全切断阀
分子式:
CAS号:
性质:高纯气体系统用语,当流量超过设定值时可自动切断流量。切断阀通常安装在气源出口与减压器之间。它对流过设定孔的压力降敏感,当达到设定压力差限时,阀门关闭。如果将启动开关打开,使活塞上下压力平衡,则又重新开始工作。此类阀的入口压力1~21MPa,工作压差0.42MPa,稳定性/重复性±10%,操作温度-40~90℃。适用材料是阀体为316不锈钢,阀座为聚四氟乙烯和氟橡胶,弹簧为不锈钢。 限速酶 rate-limiting enzyme 物质代谢是代谢物“S”在多酶体系的逐步催化下,经过一系列的中间过程,最后生成终产物“P”:S→I1→I2→I3→→→In→PI1,I2,…为中间产物。反应系统中具有最小速度常数的反应步骤即为反应速度最慢的步骤,称为限速反应。催化限速反应的酶称为限速酶,它们往往处于代谢途径的关键地位。改变限速酶活性不仅影响整个代谢反应的总速度,还可改变代谢的方向。例如,磷酸果糖磷酸激酶是糖酵解途径的限速酶,细胞内ATP/AMP比值增加可抑制此酶活性,使酵解速度减慢,同时由于激活果糖1,6-二磷酸酶而使代谢转向糖异生过程。
