seed protein quality is an important topic in the production of soybean. the quality of soybean proteins is limited by anti-nutrient proteins and low levels of essential sulfur amino acids. in this study, protein content and solubility of six cultivars were evaluated and seed storage proteins were analyzed using sds-page and scanning densitometry. the results showed that seed storage protein ba...

The objective of the present study was to investigate the effects of β-conglycinin and soya isoflavones on diabetic nephropathy (DN). DN was induced by an intravenous injection of streptozotocin (25 mg/kg) in spontaneously hypertensive rats. DN rats were divided into a non-diabetic group (C, control group) and three DN groups (D, DN with control diet; B, DN+control diet with one-eighth of casei...

In this study, soy proteins were reduced with 0.1-10mM dithiothreitol (DTT) to obtain an increasing number of sulphydryl groups (SH) with a similar particle size. Aggregation was promoted by increasing the degree of reduction when heated (100°C, 30min), resulting in larger sized aggregates (from 40 to 70nm) and a higher viscosity of the aggregate dispersion. The disulphide bond (SS) content dec...

The objective of the present study was to examine the structural and functional changes of β-conglycinin exposed to oxidizing radicals produced by FeCl₃/H₂O₂/ascorbic acid hydroxyl radical-generating system (HRGS) for 3 h at room temperature. Increasing H₂O₂ concentrations resulted in a loss of histidine residues, lysine residues, and available lysine, which was accompanied by the formation of ...

Phytate-removed and deamidated soybean β-conglycinin (PrDS) prepared by ion-exchange resins was supplemented to be 4% in the diet administered to ovariectomized rats to investigate its preventive effect on osteoporosis. The apparent calcium absorption rate decreased following ovariectomy and was not replenished by oral administration of phytate-removed soybean β-conglycinin (PrS) or casein. On ...

this research was conducted to compare effects of electron beam (eb) and gamma ray (gr) treatments at doses of 25, 50 and 75 kgy on soybean meal (sbm) ruminal degradation kinetics of crude protein (cp) and amino acids (aa). the nylon bag and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) techniques were used for this aim. ionizing radiations decreased washout and degradati...

We investigated the chromosomal organization and developmental regulation of soybean 8-conglycinin genes. The 8-conglycinin gene family contains at least 15 members divided into two major groups encoding 2.5-kilobase and 1.7-kilobase embryo mRNAs. 8-Conglycinin genes are clustered in severa1 DNA regions and are highly homologous along their entire lengths. The two groups differ by the presence ...

The aim of the present study was to confirm the effects of a commercially available mung bean protein isolate (GLUCODIA™) on glucose and lipid metabolism. The main component of GLUCODIA™ is 8S globulin, which constitutes 80 % of the total protein. The overall structure of this protein closely resembles soyabean β-conglycinin, which accounts for 20 % of total soya protein (soya protein isolate; ...
