Chitosan is the main constituent of cell wall polysaccharides from Rhizopus acetoinus HUT 1219, and these polysaccharides decrease the inhibition by phytic acid of zinc absorption. Complexes of phytic acid and chitosan formed by the reaction of amino groups and phosphate ions in a mixture of these substances. The optimum pH for complex formation was from 1.7 to 3.2, and the stoichiometric ratio was 1 : 6 for phytic acid to glucosamine. When chitosan is added in a larger proportion than this, some complexes dissociate. Much more phytic acid-chitosan complexes formed than complexes of phytic acid with zinc, of chitosan with zinc, or of phytic acid, chitiosan, and zinc together. When the pH was greater than 3.2, dissociation of phytic acid-chitosan complexes was sometimes accompanied by the formation of chitosan-zinc complexes. The result suggested that the formation of stable phytic acid-chitosan complexes at lowpH values generated free Zn2+ leading to the diffusion of such ions or the formation of chitosan-zinc complexes. Both phenomena make the adsorption of Zn2+ ions easier than in the presence of stable phytic acid-zinc complexes.

In this study, the effects of these oligosaccharides on blood pressure of spontaneously hypertensive rats (SHRs) were investigated. In the Na-AO experiment, Na-AO and NaCl groups were fed a normal diet (CE-2, Clea Japan Inc.) containing 4.0% Na-AO or 1.2% NaCl by weight, respectively. In the K-AO experiment, K-AO and KCl groups were fed CE-2 (control diet) containing 3.0% K-AO or 0.8% KCl by weight, respectively. Systolic blood pressure of the Na-AO group was significantly lower after 8 weeks, compared with the NaCl group. Systolic blood pressure of the K-AO group was also lower than that of the control group, while there was no significant difference between the KCl group and the control group. These results suggest that feeding alginate oligosaccharides suppresses the increase in systolic blood pressure of SHR and that the saccharide moiety itself may be closely related to the antihypertensive effect.","PeriodicalId":9443,"journal":{"name":"Bulletin of the Agricultural Chemical Society of Japan","volume":"98 1","pages":"783-785"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81370081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
