Vitamin B 12-binding Protein of Leukocytes
Much evidence suggests that granulocytes are a major source of serum vitamin B12-binding protein (BBP). The latter has three components: a-iglobulin BBP (Transcobalamin I, TC I), fl-globulin BBP (TC II), and a recently described third BBP. Granulocytic BBP has appeared to be identical to TC I except in electrophoretic mobility. In the present study, the dominant BBP of leukocyte extracts from s...
متن کاملLongitudinal concentrations of vitamin B(12) and vitamin B(12)-binding proteins during uncomplicated pregnancy.
BACKGROUND Because reference values for vitamin B(12) concentrations and vitamin B(12)-binding capacities for pregnant women have not been established, the reference values for nonpregnant women are often applied to assess vitamin B(12) status. The aim of the present study was to describe ranges of biochemical indices of vitamin B(12) status, including red blood cell (RBC) vitamin B(12), satura...
متن کاملRole of third serum vitamin B 12 binding protein in vitamin B 12 transport.
A third vitamin B(12) binding protein present in normal serum has been shown to participate in transport of labelled vitamin B(12) absorbed from the gut. All three vitamin B(12) binding proteins in serum were labelled at the same time after oral administration of vitamin B(12), implying that "free" vitamin B(12) reached the portal blood from the gut mucosa.
متن کاملThe role of the pancreas in vitamin B 12 absorption: studies of vitamin B 12 absorption in partially pancreatectomized rats.
The effect of partial pancreatectomy (80-90%) on vitamin B(12) absorption was studied in the rat. The absorption of 5 ng of (57)Co-labeled vitamin B(12) was significantly reduced from 70 +/-2.5% (mean +/-SE) in control and sham-operated rats to 32 +/-2.6% in partially pancreatectomized rats. Hog pancreatic extract (0.17 g/kg) improved vitamin B(12) absorption from 30.0 to 61.0% in partially pan...
