Abstract

Quercetin was described as an inhibitor of tyrosinase in an article published in Food Research International. However, it was firmly established in the literature before that this compound was a substrate of this enzyme and an antioxidant reducing tyrosinase-generated o-quinones.

摘要

有一篇发表在《国际食品研究》上的文章称槲皮素是酪氨酸酶的抑制剂。然而,在此之前的文献中已经明确确定,这种化合物是该酶的底物,也是一种抗氧化剂,可以还原酪氨酸酶生成的邻苯醌。
