Black soybean seed coat polyphenols prevent AAPH-induced oxidative DNA-damage in HepG2 cells

Black soybean seed coat extract (BE), which contains abundant polyphenols such as procyanidins, cyanidin 3-glucoside, (+)-catechin, and (-)-epicatechin, has been reported on health beneficial functions such as antioxidant activity, anti-inflammatory, anti-obesity, and anti-diabetic activities. In this study, we investigated that prevention of BE and its polyphenols on 2,2'-azobis(2-methylpropio...

Suppressive mechanism of seed coat pigmentation in yellow soybean

In soybean seeds, numerous variations in colors and pigmentation patterns exist, most of which are observed in the seed coat. Patterns of seed coat pigmentation are determined by four alleles (I, i(i), i(k) and i) of the classically defined I locus, which controls the spatial distribution of anthocyanins and proanthocyanidins in the seed coat. Most commercial soybean cultivars produce yellow se...

The N-glycosylation sites of soybean seed coat peroxidase.

Tryptic digestion of apo-soybean peroxidase (apo-SBP), with and without acetamidation, chromatographic separation of the tryptic fragments and MALDI-TOF analysis of the major components, both before and after digestion with glycopeptidase A, demonstrated the presence of six carbohydrate groups on five peptides. Five of the glycopeptides can be mapped with confidence to the peptides containing A...

Oyxgen and temperature effects on soybean seed coat respiration rates.

Soybean (Glycine max (L.) Merr) seed coat respiration rates in response to changing O(2) concentration and temperature were examined experimentally and with a mathematical analysis. The experimental observations showed seed coat respiration rates were sensitive to O(2) concentration below 0.25 micromole O(2) cm(-3). There was a steady decline in respiration rates from the saturating O(2) concen...
