In both groups glutamine was released from the leg and taken up by the splanchnic bed, while the reverse was observed for glutamate. Arterial glutamine levels were reduced by 25 per cent in the diabetics, but no differences were observed between the diabetics and controls in splanchnic or peripheral glutamine and glutamate metabolism. To assess the contribution of intestinal tissues to splanchnic glutamine uptake, arterio-portal venous differences (A-PV) were determined for plasma glutamine in four nondiabetic patients prior to elective cholecystectomy. A consistently positive A-PV difference was noted indicating net uptake of glutamine by intestinal tissues.<\/jats:p>\n               <jats:p>The findings indicate that the intestinal tract rather than the liver is the major site of splanchnic glutamine uptake and that removal of glutamine by the splanchnic bed is not augmented in diabetes. The data thus suggest that glutamine is not an important endogenous substrate for hepatic gluconeogenesis.<\/jats:p>","DOI":"10.2337\/diab.22.8.573","type":"journal-article","created":{"date-parts":[[2014,12,11]],"date-time":"2014-12-11T05:38:33Z","timestamp":1418276313000},"page":"573-576","update-policy":"https:\/\/doi.org\/10.2337\/ada-journal-policies","source":"Crossref","is-referenced-by-count":78,"title":["Glutamine and Glutamate Metabolism in Normal and Diabetic Subjects"],"prefix":"10.2337","volume":"22","author":[{"given":"Philip","family":"Felig","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Yale University School of Medicine\u2008New Haven, Connecticut 06510; the Department of Clinical Physiology, Seraphimer Hospital, and the Department of Endocrinology and Metabolism, Karolinska Hospital\u2008Stockholm, Sweden; and the Department of Medicine, Washington University School of Medicine\u2008St. Louis, Missouri 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Wahren","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Yale University School of Medicine\u2008New Haven, Connecticut 06510; the Department of Clinical Physiology, Seraphimer Hospital, and the Department of Endocrinology and Metabolism, Karolinska Hospital\u2008Stockholm, Sweden; and the Department of Medicine, Washington University School of Medicine\u2008St. Louis, Missouri 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irene","family":"Karl","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Yale University School of Medicine\u2008New Haven, Connecticut 06510; the Department of Clinical Physiology, Seraphimer Hospital, and the Department of Endocrinology and Metabolism, Karolinska Hospital\u2008Stockholm, Sweden; and the Department of Medicine, Washington University School of Medicine\u2008St. Louis, Missouri 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erol","family":"Cerasi","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Yale University School of Medicine\u2008New Haven, Connecticut 06510; the Department of Clinical Physiology, Seraphimer Hospital, and the Department of Endocrinology and Metabolism, Karolinska Hospital\u2008Stockholm, Sweden; and the Department of Medicine, Washington University School of Medicine\u2008St. Louis, Missouri 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rolf","family":"Luft","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Yale University School of Medicine\u2008New Haven, Connecticut 06510; the Department of Clinical Physiology, Seraphimer Hospital, and the Department of Endocrinology and Metabolism, Karolinska Hospital\u2008Stockholm, Sweden; and the Department of Medicine, Washington University School of Medicine\u2008St. Louis, Missouri 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David M","family":"Kipnis","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Yale University School of Medicine\u2008New Haven, Connecticut 06510; the Department of Clinical Physiology, Seraphimer Hospital, and the Department of Endocrinology and Metabolism, Karolinska Hospital\u2008Stockholm, Sweden; and the Department of Medicine, Washington University School of Medicine\u2008St. Louis, Missouri 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1167","container-title":["Diabetes"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.org\/diabetes\/diabetes\/article-pdf\/22\/8\/573\/347255\/22-8-573.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/diabetesjournals.org\/diabetes\/article-pdf\/22\/8\/573\/347255\/22-8-573.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T16:22:50Z","timestamp":1667406170000},"score":1,"resource":{"primary":{"URL":"https:\/\/diabetesjournals.org\/diabetes\/article\/22\/8\/573\/3700\/Glutamine-and-Glutamate-Metabolism-in-Normal-and"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1973,8,1]]},"references-count":0,"journal-issue":{"issue":"8","published-print":{"date-parts":[[1973,8,1]]}},"URL":"https:\/\/doi.org\/10.2337\/diab.22.8.573","relation":{},"ISSN":["0012-1797","1939-327X"],"issn-type":[{"value":"0012-1797","type":"print"},{"value":"1939-327X","type":"electronic"}],"subject":[],"published":{"date-parts":[[1973,8,1]]}}}
