Complement‐modulating water‐soluble polysaccharide fractions in two global staple cereals: rice and wheat

Abstract

BACKGROUND: There has been considerable interest recently in the physiological effects of foods on health. Research has focused on biological effects on the immune system, as substances related to the human defense system are expected to be found in staple cereals. The aims of the present study were to investigate whether water-soluble polysaccharide fractions in wheat have anticomplementary activity, which was found in rice, and to distinguish between real complement inhibitors and complement-activating substances.

Structural Features, Antitumor and Antioxidant Activities of Rice Bran Polysaccharides Using Different Extraction Methods

“…(Wang and others ). In fact, RBP have drawn considerable attentions in the fields of food, biochemistry, and pharmacology due to their potential biological and functional properties, such as antitumor and antioxidant activities (Wang and others ; Zha and others ; Wang and others ), immune‐enhancing function (Wang and others ), hypoglycemic effect (Yamagishi and others ). It can be seen from numerous reports, RBP not only has the physiological function of rice bran fiber, but also has high biological activities in antitumor, immune enhancement, antibacterial infection, antiradiation, hypoglycemic and hypolipidemic properties, and so on.…”

Biochemical and Molecular Assessment of Cooking Quality and Nutritional Value of Pigmented and Non-pigmented Whole Grain Rice

“…Soluble arabinoxylan is claimed to have beneficial effects on human health through the selective promotion of certain bacterial species of the gut flora, which is known as the prebiotic effect, and reducing the postprandial blood glucose level [58][59][60]. Although WEAX in whole grain rice and rice bran was found in little amounts, [61] reported that glycoproteins, arabinoxylan-and arabinogalactan-hydroxyproline were found in water soluble polysaccharides extracted from the rice endosperm and rice bran. They also demonstrated that glycoprotein can modulate the human complement activity.…”
