Aplicação

Sinigrin, a glucosinolate, is used as a systrate to identify, differentiate and characterize myrosinase(s)/thioglucoside glucohydrolase(s)/thioglucosidase(s). Sinigrin is used as a reference material in procedures for the isolation and identification of glucosinolates.

Ações bioquímicas/fisiológicas

A β-D-thioglucopyranoside occurring in black mustard seeds and horseradish root. Substrate for thioglucosidase.

Isothiocyanates have been implicated in the cancer-protective effects of brassica vegetables. When cabbage is consumed, sinigrin is hydrolysed by plant or microbial myrosinase partly to allyl isothiocyanate (AITC), which is mainly excreted as N-acetylcysteine conjugates (NAC) of AITC in urine.

In nature, moths encounter nutritious and toxic substances in plants, and thus have to discriminate between a diversity of tastants. Whereas olfactory learning allowing memory of nutritious plants is well demonstrated, little is known about learning and memory of toxic

Plants interact with many different species throughout their life cycle. Recent work has shown that the ecological effects of multispecies interactions are often not predictable from studies of the component pairwise interactions. Little is known about how multispecies interactions affect

A simple procedure for extracting and purifying sinigrin from Oriental mustard (Brassica juncea) meal using cold water was developed. Subsequently, the chemical degradation of sinigrin due to enzymatic activity was monitored using (1)H NMR spectroscopy over the course of 30
