Influence of phosvitin and calcium gluconate concentration on permeation and intestinal absorption of calcium ions.

Dolińska B, Łopata K, Mikulska A, Leszczyńska L, Ryszka F - Biol Trace Elem Res (2012)

Bottom Line: The effect of egg yolk phosvitin on the permeation and absorption of calcium was investigated in vitro in relation to calcium gluconate concentration.Obtained results indicate that phosvitin significantly reduces the intestinal calcium absorption from 1 and 10 mM of calcium gluconate solution.The process of calcium permeation increases under phosvitin influence when calcium gluconate concentrations rise up to 10 mM.

ABSTRACT
The effect of egg yolk phosvitin on the permeation and absorption of calcium was investigated in vitro in relation to calcium gluconate concentration. Obtained results indicate that phosvitin significantly reduces the intestinal calcium absorption from 1 and 10 mM of calcium gluconate solution. It is associated with the formation of the complex of Ca (II) ions with phosvitin. The process of calcium permeation increases under phosvitin influence when calcium gluconate concentrations rise up to 10 mM. At a higher concentration of calcium gluconate (20 mM), no effect of phosvitin was seen on permeation of calcium ions.

Fig3: Influence of phosvitin on Ca(II) ions permeation at 20 mM calcium gluconate concentration during 5 h

Mentions: At an even higher concentration of calcium gluconate (20 mM), 84 mg/l (11%) of Ca(II) ions passed from D to A and 362 mg/l were absorbed. Addition of phosvitin did not change Ca(II) permeation or absorption at this concentration. The influence of phosvitin on the dynamics of Ca(II) permeation from 20 mM calcium gluconate solution is given in Fig. 3.Fig. 3
