Petroselinic add (Z)-6-octadecenoic acid]. H3C-(CH2),o-CH=CH-(CH2)4-COOH, C,gH3402, Mr 282.47, mp. 32-33°C, bp. 215-217°C (0.2-0.3 kPa) soluble in organic solvents. P. was first found as the glycerol ester in the seed oil of parsley (Petro-selinum crispum), it is a characteristic component of the seed oils of umbelliferous and ivy plants. The fatty acids of these seed oils contain up to 87% P. (e.g. fat coriander oil, 75-80%). P. is also used as a starting material in oleochemistry. For nutritional-physiological aspects, see Lit.. ... 

The book starts with an introductory overview, which is intended to refresh the reader s memory on key aspects of free radicals and reactions thereof. Subsequent sections cover free radicals and food chemistry, natural antioxidants, and nutritional biochemistry and health. In the food chemistry section, topics range from analysis of free radicals within food matrices to Maillard reactions, emulsions, dairy, and meat products. In the antioxidant section, results are presented on the efficacy of antioxidants from tea, seeds, and selected naturally occurring compounds. Finally, in the nutritional biochemistry and health section, free radical inhibition is discussed in relationship to biochemical paths and cancerous cell cultures. 

A leaf urease has been described in extracts from nodulated Glycine max grown on nitrogen-free medium, hence dependent on ureides for nitrogen nutrition (Kerr et al., 1983). This enzyme was characterized as a true urease rather than urea dehydrogenase or urea amidolyase, and differed from the seed enzyme in several aspects The seed enzyme has a broad pH optimum from 5 to above 9, while the leaf enzyme has a bimodal pH dependence with sharp optima at 5.25 and 8.75. The for urea for the leaf enzyme was about 1 xaM,...
