In the biosynthesis of fatty acids from 1-(14)C-acetate by intact spinach chloroplasts, ATP and Triton X-100 exert opposing effects on the conversion of palmitic acid to stearic acid; thus, ATP decreases the conversion and Triton X-100 increases the conversion. Changes in the availability of photosynthetically generated reduced nicotinamide adenine dinucleotide phosphate apparently does not markedly affect the C(16)-C(18) ratio. Various H(2)O(2)-generating systems, such as viologen dyes, inhibit oleate synthesis from acetate and cause stearate to accumulate. Catalase partially reverses the effect of these days.
在完整的菠菜叶绿体中,从 1-(14)C-乙酸盐生物合成脂肪酸时,ATP 和 Triton X-100 对棕榈酸转化为硬脂酸有相反的影响;因此,ATP 降低了转化,而 Triton X-100 增加了转化。光合作用产生的还原型烟酰胺腺嘌呤二核苷酸磷酸的可用性的变化显然不会显著影响 C(16)-C(18) 比值。各种 H(2)O(2)生成系统,如紫精染料,抑制从乙酸盐合成油酸,并导致硬脂酸积累。过氧化氢酶部分逆转了这些天的影响。
