| protease inhibitors: possible anticarcinogens in edible seeds. | protease inhibitors, which are common constituents of seeds (rice, beans, and maize) have been shown to inhibit breast, colon, and skin cancers in animal experiments. epidemiological studies have shown that diets rich in these components (ie seed proteins) decrease the occurrence of prostatic, breast, and colon cancers in man. we have demonstrated that a typical purified inhibitor from soybeans, the bowman-birk inhibitor, is excreted in the feces complexed with digestive proteases from the duode ... | 1983 | 6346296 |
| lectin receptors as markers of lymphoid cells. i. demonstration in tissue section by peroxidase technique. | the distribution of lectin binding receptors in human lymphoid tissue (lymph node and tonsil) was studied in an effort to identify lectins with potential application as cell markers. using a simple peroxidase technique applicable to formalin-fixed, paraffin-embedded tissue, the binding properties of five lectins were investigated: concanavalin a (con a), arachis hypogaea (peanut agglutinin), lotus tetragonolobus (asparagus pea), glycine max (soybean agglutinin) and bandeiraea simplicifolia. thre ... | 1984 | 6380299 |
| comparison of in vitro and in vivo measurements of dietary ca exchangeability and bioavailability. | an in vitro method for measuring dietary mineral exchangeability (miscibility with an extrinsic isotopic tracer) was tested by comparison with in vivo measurements in rats. collards, spinach and soybeans, intrinsically labeled with 45ca, were fed to rats together with extrinsically added 47ca. absorption of both tracers was determined by measuring their concentrations in the femur 2 days after consumption of the labeled test meals. the same intrinsically and extrinsically labeled foods were dige ... | 1983 | 6401805 |
| [inhibitory effect of lectins extracted from arachis hypogea and soybeans on germ cell migration in the embryo of xenopus laevis (amphibia, anura)]. | effect of injection of arachis hypogea (pna) and soybean (sba) lectins on the migration of xenopus primordial germ cells (pgcs) were investigated. pna inhibited almost entirely the pgcs migration, more than sba. our results indicated that the inhibition of the migration could be a consequence of the lectin-induced alterations of cell surface properties. | 1983 | 6412978 |
| gossypol in cottonseed products: toxicology and inactivation. | the little attention given to the potential of cottonseeds as food for monogastric animals and man is due to the presence of toxic principles in them, especially gossypol. the injury to livestock associated with ingestion of cottonseeds results from the unfavorable physiological effect of gossypol per se, as well as from its adverse effects on the protein nutritive value of the food (mainly by rendering lysine metabolically unavailable). various approaches have been employed to overcome these pr ... | 1983 | 6414436 |
| differentiation of bacillus anthracis and other bacillus species by lectins. | bacillus anthracis was agglutinated by several lectins, including those from griffonia simplicifolia, glycine max, abrus precatorius, and ricinus communis. some strains of bacillus cereus var. mycoides (b. mycoides) were strongly reactive with the lectin from helix pomatia and weakly reactive with the g. max lectin. the differential interactions between bacillus species and lectins afforded a means of distinguishing b. anthracis from other bacilli. b. cereus strains exhibited heterogeneity with ... | 1984 | 6418761 |
| radiolabeled iron in soybeans: intrinsic labeling and bioavailability of iron to rats from defatted flour. | soybeans can be efficiently labeled with radiolabeled iron by supplying the iron via a nutrient culture medium as an iron salt or as a chelate. by using dual labeled iron and edta, it was determined that none of the chelator was transported to the shoots with the iron. therefore, the use of chelated iron as the iron source in the nutrient medium should not affect assessments of bioavailability of iron from plants. bioavailability (determined from whole-body retention curves of 59fe in rats) of i ... | 1984 | 6427432 |
| pentane formation during the anaerobic reactions of reticulocyte lipoxygenase. comparison with lipoxygenases from soybeans and green pea seeds. | the lipoxygenases from reticulocytes, soybeans and green pea seeds produce pentane in an anaerobic assay containing 13ls-hydroperoxy-9-cis, 11-trans-octadecadienoic acid and 9,12-all-cis-octadecadienoic acid. the presence of oxygen strongly inhibits pentane formation by the three enzymes. relative to the lipoxygenase activity with linoleic acid as substrate, soybean lipoxygenase is 4-times as effective in pentane formation as the lipoxygenases from reticulocytes or green pea seeds. pentane forma ... | 1984 | 6433987 |

| identification of benzo[a]pyrene quinone in soybean leaves. | soybean seeds (glycine max) were grown in soil containing 10 ppm of benzo[a]pyrene (bap). after 76 days growth, three kinds of quinones, namely bap-1,6-, 3,6- and 6,12-quinones, were isolated and identified. however, the formative mechanism of the quinones in leaves has yet to be determined. | 1984 | 6541371 |
| localization of four genes for three trnaleu's on the physical map of the soybean (glycine max l.) chloroplast genome. | three trnasleu from soybean chloroplasts were isolated and hybridized to restriction fragments of soybean chloroplast dna. based on the hybridization pattern, the locations of four genes coding for trna1leu, trna2leu (two genes trna2aleu and trna2bleu, are present in the inverted repeat region) and trna3leu were determined on the physical map of the soybean chloroplast genome. | 1984 | 6541611 |
| the amino acid sequence of the a2b1a subunit of glycinin. | the amino acid sequences of the acidic and basic components of the a2b1a subunit of glycinin, the major seed reserve protein of the soybean (glycine max l. merr.), were determined. they contain 278 and 180 amino acids, respectively, and have molecular weights of 31,600 +/- 100 and 19,900 +/- 100. the molecular weight of the acidic component is considerably less than that estimated by sodium dodecyl sulfate-gel electrophoresis (37,000). sequence heterogeneity was detected at several positions sca ... | 1984 | 6541652 |
| the complete amino acid sequence of the a3 subunit of the glycinin seed storage protein of the soybean (glycine max (l.) merrill). | the amino acid sequence of the a3 subunit, an acidic subunit of the glycinin seed storage protein of the soybean (glycine max (l.) merrill), has been determined by sequence analysis of the peptides obtained by cyanogen bromide cleavage followed by enzymatic digestion and partial acid hydrolysis. the a3 subunit is composed of 410 amino acids (mr approximately 46,000). it has been confirmed that there are conserved, repeated domains within the subunit. a comparison of the nh2-terminal sequence of ... | 1984 | 6542104 |
| phosphatidylinositol turnover in isolated soybean membranes stimulated by the synthetic growth hormone 2,4-dichlorophenoxyacetic acid. | phospholipids of plant membranes isolated from homogenates of dark-grown hypocotyls of soybean (glycine max l.) undergo rapid and specific degradative changes. the degradation of phosphatidylinositol (pi) in such membranes is enhanced in the presence of the synthetic auxin, 2,4-dichlorophenoxyacetic acid (2,4-d), measured as the hydrolysis of pi or by an enhancement of [3h]inositol incorporation into membrane-associated pi stimulated by mn2+, but not dependent upon added ctp, mg2+, or diglycerid ... | 1984 | 6542567 |
| studies on the inhibition of pancreatic and microbial lipases by soybean proteins. | a protein, molecular weight 70,000 that inhibits pancreatic lipase has been isolated from soybean seeds. inhibition is not reversed by colipase unless bile salts are added to the assay system. inhibitory properties of the purified protein are very similar to those of serum albumin or alpha-lactoglobulin. it has been confirmed that, during intestinal lipolysis of dietary fats, bile salts play an essential role for the activation of the lipase-colipase system in the presence of inhibitory proteins ... | 1984 | 6542933 |
| [genetic improvement of grain legumes of importance to latin american diet and the soy bean]. | common beans and soybeans can be considered as the most important food legumes in the latin american nutritional context, each of them presenting specific problems. the production of common beans has not increased in the last decade, and insects and diseases attacks are menacing it. on the other hand, soybeans have shown a tremendous increase in production, becoming rapidly an important export cash crop. however, its use in human consumption is quite restricted, in spite of the efforts of some c ... | 1984 | 6543422 |
| the use of blends of cassava flour and extruded full-fat soybeans in diets for broiler chickens. | a study was conducted to determine the effects of blending different levels of a low-prussic acid cassava flour with extruded full-fat soybeans in diets for growing broiler chickens. the full-fat soybeans contribute oil which increases the energy content of the diet, aids in overcoming the dusty nature of cassava, and provide high-quality protein. one-third, two-thirds, and all of the maize was replaced by cassava in diets with none, 12.5 and 25% extruded full-fat soybeans. diets were fed in pel ... | 1984 | 6544063 |
