Heme oxygenases are the rate—limiting enzymes in the degration of heme.

血红素加氧酶是血红素降解过程的限速酶。

Endogenous carbon monoxide is a gaseous messenger that is the degration of heme.

内源性一氧化碳是一种气体信使分子，是血红素的降解产物。

Endogenous carbon monoxide is a gaseous messenger, which is the degration product of heme.

内源性一氧化碳是一种气体信使分子, 是血红素的降解产物.

The comparing experiment results of swirling jet and ultrasonic cavitations degradation indicated that the degration efficiency of swirling jet was far greater than that of ultrasonic.

涡流空化降解和超声空化降解的对比试验结果表明，涡流空化降解效率远大于超声空化。
