Flavonoids and cinnamates are widespread phenolic secondary metabolites synthesized by plants for defensive purposes. Many foods and beverages contain high levels of phenolic compounds. Certain phenolics in the diet are particularly bioactive and have pronounced effects on mammalian cells. These effects, together with epidemiological studies and animal models, have led to the hypothesis that dietary phenolics contribute to the health benefits of a diet rich in fruit and vegetables. This paper examines the biochemistry of the uptake and metabolic route of two groups of plant phenolics, the flavonols and hydroxycinnamates.
黄酮类化合物和肉桂酸酯是植物为防御目的而合成的广泛存在的酚类次生代谢产物。许多食品和饮料含有高水平的酚类化合物。饮食中的某些酚类物质具有特别的生物活性，对哺乳动物细胞有显著影响。这些影响，连同流行病学研究和动物模型，引发了这样一种假说，即饮食中的酚类物质有助于富含水果和蔬菜的饮食对健康有益。本文研究了两类植物酚类物质，即黄酮醇和羟基肉桂酸酯的摄取和代谢途径的生物化学。
