Inhibition of cholesterol absorption by phytosterol-replete wheat germ compared with phytosterol-depleted wheat germ

Phytosterol glycosides reduce cholesterol absorption in humans.

Dietary phytosterols inhibit intestinal cholesterol absorption and regulate whole body cholesterol excretion and balance. However, they are biochemically heterogeneous and a portion is glycosylated in some foods with unknown effects on biological activity. We tested the hypothesis that phytosterol glycosides reduce cholesterol absorption in humans. Phytosterol glycosides were extracted and puri...

Wheat Germ Agglutinin

Procedures for the isolation, purification, and crystallization of wheat germ agglutinin are described. The agglutinin was purified 184-fold to homogeneity from commercial wheat germ lipase. A molecular weight of 23,500 was estimated for the protein by means of sedimentation equilibrium and sodium dodecyl sulfate gel electrophoresis. The agghxtinin is a glycoprotein. Amino acid and carbohydrate...

Inhibition of mating pair formation by wheat germ agglutinin and wheat germ agglutinin-binding substances in Paramecium caudatum cells

In this study, we revealed that the lectin wheat germ agglutinin (WGA) and its specific binding sugars, N-acetylneuraminic acid (NeuAc) and Nacetylglucosamine (GlcNAc), inhibited mating pair formation in Paramecium caudatum. The concentrations that caused 50% inhibition (IC50) were 17 nM, 3 mM and 30 mM, respectively. Using FITCWGA, it was shown fluorescence-cytochemically that WGA bound to the...

aBatchSystem Using Wheat Germ Extract

modified and unnatural amino acids into protein are possible.t) However, the relatively small amount of product due to early stopping of the translational reaction has been the primary bottleneck for its application. To overcome this problcm, Spirin and co-workers developed a continuous-fiow cell-free translation system, called the CFCF system, in 1988.2) In this system, the protein synthesis i...
