Protein-rich rape seed residues from biodiesel production plants are rich in phenolic compounds, glucocinolates and phytic acid. Phenolic compounds and phytic acid could be used as potent antioxidants in cosmetic and pharmaceutical formulations (Shamsuddin, 1995 Amarowicz and Shahidi, 1994 Wanasundara et al., 1996 Oatway et al., 2001). Derivatives from glucosinolate hydrolysis, including isothiocyanates, thiocyanates and nitriles, could be used as anticarcinogenic agents, biopesticides and flavour compounds (Halkier and Gershenzon, 2006). 

Phytic acid will form pyrophosphate complexes (10.36c). Phosphates of myo-inositol containing less than 6 ester OP(0)(OH)2 gronps have been obtained from plants and detected in soils. Mixtures of these lower phosphates are known to be produced by enzyme-catalysed hydrolysis of phytic add, and inositol monophosphate is a degradation product from phosphatidyl inositol (Chapter 11.3). Some varieties have been laboratory synthesised [50-52].
