Definition of catechol in English:

catechol

noun ˈkatɪkɒlˈkatɪtʃɒlˈkatəˌkôl

mass nounChemistry

A crystalline compound obtained by distilling catechu.
〔化〕儿茶酚，儿茶酸，邻苯二酚
Chemical formula: C₆H₄(OH)₂
Example sentencesExamples
- Similarly, the peroxidase activity was assayed from the oxidation of catechol by H 2 O 2 in presence of the extract.
- This surprised the researchers, because their previous work had suggested that the intestinal enzyme catechol - O methyltransferase played a big part in digesting flavanols, and they expected to see more O methylation going on.
- Acrolein, hydroquinone, catechol, and benzo- [a] pyrene have demonstrated immunosuppressive effects in cell and animal models.
- To determine this, we crossed acd5 with a well-characterized transgenic plant harboring the nahG gene, whose product metabolizes SA to the inactive catechol.
- So the problem was how to change this catechol without affecting the drug's ability to interact at the receptor.

Origin

Late 19th century: from catechu + -ol.
