ROLE OF 12/15 LIPOXYGENASE EXPRESSION IN LIPID METABOLISM, ATHEROSCLEROSIS AND INSULIN RESISTANCE
12/15 lipoxygenase (LO) is a member of a family of enzymes that can catalyze the stereospecific incorporation of oxygen into polyunsaturated fatty acids (PUFAs), forming a series of bioactive lipid mediators. Though lipid mediators produced by 12/15LO have the potential to affect lipid metabolism …

Differences in lipoxygenase activity as related to cultivar differences in superficial scald of apples
The relationship between lipoxygenase activity (LOX) and superficial scald was studied in the four apple cultivars (Malus domesticus Borkh.), Granny Smith (GS), Red Delicious (RD), Golden Delicious (GD) and York (YK) to determine if LOX is the genetic source of superficial scald or a means of …

Kinetics of Acid Inactivation of Soybean Lipoxygenase and Its Effects on the Functional Properties of Soy Protein
Inactivation of soybean lipoxygenase by acid pH was investigated by grinding whole soybeans in water acidified with HCl. The enzyme was found to be completely and irreversibly inactivated at pH 3.0 and below. From a study of enzyme kinetics of lipoxygenase extracted from the acidified soy slurries, …
