Glucosinolates aliphatic

Fig. 4.1 Sinigrin is an aliphatic glucosinolate that occurs at significant levels in the human diet, notably in mustard and Brussels sprouts. When brought into contact with myrosinase, derived either from plant cells or from colonic bacteria, it is broken down to yield a variety of products including the acrid, volatile, biologically active compoimd...

The name canola was registered by the Western Canadian Oilseed Cmshers in 1978 and subsequently transferred to the Canola Council of Canada in 1980. It included those cultivars containing less than 5% emcic acid in the oil and 3 mg/g aliphatic glucosinolates in the meal. In 1986, the definition of canola was amended to B. napus and B. rapa lines with less than 2% emcic acid in the oil and less than 30 pmol/g glucosinolates in the air-dried, oil-free meal. The oil was added to the Generally Recognized as Safe (GRAS) list of food products in the United States.

Glucosinolates are divided into three classes based on the general chemical properties of the amino acid precursors. Aliphatic glucosinolates variously contain a straight carbon chain derived from methionine or a branched chain fix)m isoleucine, leucine or valine. Indole glucosinolates are formed from tryptophan, and the aromatic glucosinolates are derived from phenylalanine or tyrosine. ... 

The formation of aliphatic glucosinolates does not end with the sulfation step. The various substituents of the glucosinolate molecule, especially the R group, can be modified further as illustrated in Figure 2.6. Based on the different glucosinolate...
