The uncoupler desaspidin is labile in the presence of oxidants at alkaline pH values. It also undergoes chlorophyll-sensitized photooxidation at a more acid pH. The products of the oxidation appear to have negligible activity in inhibiting electron transfer and photophosphorylation.Failure of desaspidin to uncouple in the presence of oxidants used as cofactors of noncyclic electron flow is presumably the result of this irreversible degradation of the desaspidin molecule during the early minutes of illumination or preincubation.
解偶剂去甲槟榔次碱在碱性 pH 值存在氧化剂时不稳定。它在更酸性的 pH 值下也会经历叶绿素敏化的光氧化。氧化产物似乎在抑制电子传递和光合磷酸化方面没有显著活性。去甲槟榔次碱在作为非循环电子流辅助因子的氧化剂存在下不能解偶，这可能是由于在光照或预孵育的最初几分钟内，去甲槟榔次碱分子的这种不可逆降解所致。
