Glucobrassicinとは 意味・読み方・使い方

Glucobrassicin is a type of glucosinolate that can be found in almost all cruciferous plants, such as cabbages (e.g.broccoli), mustards, cress, and woad. As for other glucosinolates, degradation by the enzyme myrosinase is expected to produce an isothiocyanate, indol-3-ylmethylisothiocyanate. However, this specific isothiocyanate is expected to be highly unstable, and has indeed never been detected. The observed hydrolysis products when isolated glucobrassicin is degraded by myrosinase are Indole-3-carbinol and thiocyanate ion (plus glucose, sulphate, and hydrogen ion), which are envisioned to result from a rapid reaction of the unstable isothiocyanate with water. However, a large number of other reaction products are known, and indole-3-carbinol is not the dominant degradation product when glucosinolate degradation takes place in crushed plant tissue (Agerbirk et al., 2009) or in intact plants (Clay et al., 2009; Bednarek et al., 2009).
