The ability of 19 structural analogs of propyl gallate to inhibit purified soybean seed (Glycine max [L.] Merr. var. Ransom) lipoxygenase-2 (EC 1.13.11.12) was determined. The results indicate that the o-dihydroxy and not the ester function of propyl gallate is essential for inhibition of
Novel magnetic molecularly imprinted polymers (MMIPs) with multiple-template based on silica were modified by four types of deep eutectic solvents (DESs) for the rapid simultaneous magnetic solid-phase extraction (MSPE) of tanshinone Ⅰ, tanshinone ⅡA, and cryptotanshinone from Salvia miltiorrhiza
Three lipoxygenase isozymes are synthesized in developing soybean (Glycine max [L.] Merr. cv Williams) embryos and are found in high levels in cotyledons of mature seeds (B Axelrod, TM Cheesbrough, S Zimmer [1981] Methods Enzymol 71: 441-451). Upon germination at least two new protein species appear
A disengagement of the cyanide-resistant, alternative respiratory pathway in soybean (Glycine max (L.) Merr.) callus tissue was observed prior to the start of deoxyisoflavone production stimulated by addition of the cytokinin benzyladenine. To test whether this loss of alternativepathway activity
Mitochondria from axes of Glycine max (L.) Merr. cv. Chippewa 64 seedlings purified on discontinuous Percoll gradients exhibited classical cyanide-resistant respiration. These mitochondria also possessed lipoxygenase activity, as determined by O(2) uptake in the presence of 0.8 millimolar linoleic
The initial burst of respiratory activity (Q(o) (2)) of imbibing soybean (Glycine max [L.] Merr. var. Wayne) seed tissue is cyanide-insensitive, and sensitive to salicylhydroxamate: presumptive evidence for the presence of alternate respiration. The initial O(2) consumption is also highly sensitive
Dietary polyphenols are antioxidants that can scavenge biological free radicals, and chemoprevent diseases with biological oxidation as their main etiological factor. In this paper, we review our laboratory data vis-ὰ-vis available literature on prostate cancer chemopreventive substances in Nigerian
Highly purified soybean (Glycine max L. Merr.) plasma membranes exhibit a lipoxygenase activity with a pH optimum in the acidic (5.5-6.0) range and with a Km value of 200 microM for both linolenic and linoleic acids. This activity is inhibited by nordihydroguaiaretic acid (NDGA), salicylhydroxamic
