Fetal plasma lactate concentrations averaged 2.12 +\/- 0.25 mM and glucose concentrations averaged 9.3 +\/- 1.3 mg\/100 ml. Total plasma turnover of lactate was 5.22 +\/- 0.7 nmol\/h and that of glucose was 3.48 +\/- 0.63 nmol x h-1 x kg fetal weight-1. Lactate was converted to glucose at a rate of 1.35 +\/- 0.64 mmol x h-1 x kg fetal weight-1, which represented 21.6 +\/- 6.0% of the lactate turnover. The percentage of glucose coming from lactate was 48.9 +\/- 15.2. The specific activity of maternal plasma glucose was less than 4% of the specific activity of glucose observed in fetal plasma. No radioactivity could be detected in maternal plasma lactate. The data show that the ovine fetus or the fetal-placental unit can convert lactate to glucose by days 123-128 of gestation. A general model presented describes carbohydrate metabolism in the ovine placenta and fetus.<\/jats:p>","DOI":"10.1152\/ajpendo.1980.239.3.e208","type":"journal-article","created":{"date-parts":[[2017,12,21]],"date-time":"2017-12-21T21:17:40Z","timestamp":1513891060000},"page":"E208-E214","source":"Crossref","is-referenced-by-count":6,"title":["Glucose and lactate metabolism in vivo in ovine fetus"],"prefix":"10.1152","volume":"239","author":[{"given":"R.
