Protein metabolism in the mouse during pregnancy and lactation.
Protein synthesis was measured in vivo in the whole body and in a number of individual tissues in mice at various stages of pregnancy and lactation. The absolute rate of protein synthesis in the whole body increased from 640 mg/day in virgin mice to 1590 mg/day by day 18 of pregnancy, and to 2100 mg/day by day 15 of lactation. Large proportions of these increments were contributed by the rapidl...
متن کاملMetabolism in normal pregnancy
During pregnancy, the mother adapts her metabolism to ensure the continuous supply of nutrients to the fetus in order to sustain its exponential growth. Among those nutrients crossing the placenta, glucose is quantitatively the most important, followed by amino acids. Although lipids cross the placenta in much lower proportion than the other nutrients, maternal lipid metabolism is consistently ...
متن کاملThe effect of maternal hypothyroidism during pregnancy on carbohydrate metabolism in adulthood in rats
Introduction: Many of the diseases of adulthood are originated from the intrauterine conditions during fetal life. Because of the importance of thyroid hormones in growth and development of the fetus, the effects of maternal hypothyroidism on carbohydrate metabolism in adulthood was investigated. Methods: Pregnant rats were divided into the fetal hypothyroidism (FH) and the control (C) group...
متن کاملSerine metabolism in human pregnancy.
Serine plays an important role in intermediary metabolism as a source of one carbon pool for nucleotide biosynthesis, as a precursor for glycine and glucose, and as a contributor to cysteine biosynthesis. A unique serine-glycine cycling between the liver and the placenta has been demonstrated in the sheep fetus. We hypothesized that, because of serine's role in growth and development, significa...
متن کاملMethionine metabolism in human pregnancy.
BACKGROUND Hyperhomocysteinemia during pregnancy, which is a consequence of perturbations in methionine and/or folate metabolism, has been implicated in adverse outcomes such as neural tube defects, preeclampsia, spontaneous abortion, and premature delivery. The adaptive changes in methionine metabolism during pregnancy in humans have not been determined. OBJECTIVE Our objective was to examin...
