Question

求翻译如下生物化学一段文字

Flavonoids and other phenolic compounds are antioxidants that contribute to the high
antioxidant capacity observed in certain fruits and vegetables. There are several thousand
different flavonoids present in plants, and many of them have antioxidant activities
(112). The antioxidant capacities, measured as oxygen radical absorbance assay (ORAC)
of some flavonoids were found to be several times stronger on the basis of molar concentration than
vitamins E and C (112).Such phenolic compounds have already been
implicated as playing a role in the protection that fruits and vegetables have against chronic
diseases (112). However, the extent to which these potentially important antioxidants can
be absorbed is not clear, although early evidence indicates that substantial quantities of the flavonoids are absorbed.Antioxidant Capacity

Answer 1

类黄酮和其他酚类化合物是抗氧化剂，可以观察到这些物质使得某些水果和蔬菜具有高抗氧化能力。存在于植物的几千种不同的黄酮类化合物中，一部分会具有抗氧化效果【112】。通过氧化自由基吸收能力(Oxygen Radical Absorbance Capacity，ORAC)测定发现，每摩尔浓度下，一些黄酮类化合物比维生素E和维生素C的抗氧化能力强几倍【112】。已经确认，这些酚类化合物在水果和蔬菜对抗慢性疾病时发挥作用【112】。然而，尽管早期的证据表明，相当大量的类黄酮被吸收了，但我们仍不清楚这些潜在的重要的抗氧化剂可以在多大程度上被吸收。抗氧化能力……
