The plants contain the enzyme myrosinase, which, in the presence of water, cleaves off the glucose group from a glucosinolate. [11] The remaining molecule then quickly converts to an isothiocyanate, a nitrile, or a thiocyanate; these are the active substances that serve as defense for the plant. Glucosinolates are also called mustard oil ...
Sinigrin or allyl glucosinolate is a glucosinolate that belongs to the family of glucosides found in some plants of the family Brassicaceae such as Brussels sprouts, broccoli, and the seeds of black mustard (Brassica nigra).
The mustard oil bomb, formerly known as the glucosinolate–myrosinase complex, is a chemical herbivory defense system found in members of the Brassicaceae (or cabbage family). The mustard oil bomb requires the activation of a common plant secondary metabolite, glucosinolate , by an enzyme, myrosinase .
Many isothiocyanates from plants are produced by enzymatic conversion of metabolites called glucosinolates. A prominent natural isothiocyanate is allyl isothiocyanate, also known as mustard oils. Cruciferous vegetables, such as bok choy, broccoli, cabbage, cauliflower, kale, and others, are rich sources of glucosinolate precursors of ...
Examples are provided by cruciferous vegetables including mustard, cabbage, and horseradish, which release pungent oils containing glucosinolates when the plant material is chewed, cut, or otherwise damaged. [7] The odorous components of garlic are thought to have evolved to deter insects. [8] Common plants known as sources of antifeedants
Glucobrassicin is a type of glucosinolate that can be found in almost all cruciferous plants, such as cabbages, broccoli, mustards, 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 ...
Gluconasturtiin or phenethyl glucosinolate is one of the most widely distributed glucosinolates in the cruciferous vegetables, mainly in the roots, and is probably one of the plant compounds responsible for the natural pest-inhibiting properties of growing crucifers, such as cabbage, mustard or rape, in rotation with other crops.
Brassica rapa is a plant species that has been widely cultivated into many forms, including the turnip (a root vegetable), komatsuna, napa cabbage, bomdong, bok choy, and rapini. Brassica rapa subsp. oleifera is an oilseed commonly known as turnip rape, field mustard, bird's rape, and keblock.
