S_<20,W> values were 14.4 and 1.8 for κ-casein and α_S-casein, respectively, in the absence of Ca. Caseins were found in gel filtration to be brought into polymerization at such low Ca concentrations that no aggregated particles were visible. α_S-κ Complex did not grow as fast as α_S-casein did in the presence of Ca. The amounts of Ca bound to caseins were determined at pH7 and 8 in the presence of 1 to 10mM Ca using; equilibrium dialysis, gel filtration and centrifugation. The minimum amount of Ca necessary for the initiation of α_S-casein precipitation is posited to be about 12 moles per mole casein. Weak adsorption of Ca, due to some structural factor, was indicated since the amounts of bound Ca obtained by centrifugation were remarkably lower than those determined by the other two methods. The state of bound Ca were studied by gel filtration of ^<45>Ca-caseinates with an eluant containing no Ca. More Ca was bound to the α_S-κ complex in the early stage of the reaction than to the same amount of α_S-casein only. But the amount of Ca bound to the complex did not vary with reaction time, while that bound to α_S-casein increased greatly, accompanied by the progress of polymerization. The intensity of Ca binding to κ-casein was so weak that only a small amount of Ca was eluted together with κ-casein in the gel filtration of Ca-κ-caseinate.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三好, 正満","creatorNameLang":"ja"},{"creatorName":"ミヨシ, マサミツ","creatorNameLang":"ja-Kana"},{"creatorName":"Miyoshi, Masamitsu","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊吹, 文男","creatorNameLang":"ja"},{"creatorName":"イブキ, フミオ","creatorNameLang":"ja-Kana"},{"creatorName":"Ibuki, Fumio","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"金森, 正雄","creatorNameLang":"ja"},{"creatorName":"カナモリ, マサオ","creatorNameLang":"ja-Kana"},{"creatorName":"Kanamori, Masao","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000078888.pdf","filesize":[{"value":"861.3 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000078888.pdf","url":"https://kpu.repo.nii.ac.jp/record/4889/files/KJ00000078888.pdf"},"version_id":"9911a2d0-d6b9-4281-af35-0d697368bcfb"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper"}]},"item_title":"Studies on κ-Casein of Bovine Milk IV : The binding of calcium to α_S-, and κ-casein (Agricultural Chemistry)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Studies on κ-Casein of Bovine Milk IV : The binding of calcium to α_S-, and κ-casein (Agricultural Chemistry)","subitem_title_language":"en"}]},"item_type_id":"3","owner":"14","path":["415"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4889","relation_version_is_last":true,"title":["Studies on κ-Casein of Bovine Milk IV : The binding of calcium to α_S-, and κ-casein (Agricultural Chemistry)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-24T06:16:28.466241+00:00"}
