Abstract
Density and viscosity of D (+) galactose and D (+) lactose mono hydrates in aqueous solution of sodium butyrate solutions have been determined experimentally at 308 K. The results obtained from density and viscosity measurement have been used to calculate the, apparent molal volume фv, partial molal volume ф0v, transfer volume ∆ф0tr at infinite dilution, A and B coefficient and Sv experimental slope. The results are interpreted in terms of solute-co- solute and solute-solvent interactions in these systems. It has been observed that there exist strong solute-solvent and solute-solute interactions and complex formation between in these ternary systems. The properties of the D (+) galactose and D (+) lactose mono hydrates in aqueous solution of sodium butyrate solutions are discussed in terms of the structure making and hydrogen bonding effect.
Highlights
The study of thermodynamic properties of carbohydrates in aqueous and non-aqueous solvent is an important step for understanding their behavior biological fluids containing different ionic species
We present in this paper, D (+) galactose and D (+) lactose mono hydrates in aqueous solution of sodium butyrate the study of interaction between them at 308 K
We report densities, ρ and viscosity, η of D(+) galactose and D(+) lactose mono hydrate (0.00, 0.02,0.03,0.05,0.07 & 0.08)M in aqueous solution of sodium butyrate(0.00,0.03,0.05,0.08 & 0.10) M solutions have been determined experimentally at 308K.From these experimental data a number of thermodynamic parameters namely, apparent molalvolume фv partial molalvolume ф0v, transfer molalvolume, ∆фtr0at infinite dilution and experimental slopes Sv,A and B coefficients respectively have been calculated
Summary
The study of thermodynamic properties of carbohydrates in aqueous and non-aqueous solvent is an important step for understanding their behavior biological fluids containing different ionic species It can provide useful information regarding conformational stability and interaction in the ternary system. Aqueous solutions of sodium butyrate are biologically and chemically important and these are widely used in biological applications It can promote growth of beneficial bacteria and inhibit the growth of harmful bacteria in the gastrointestinal tract. We report densities, ρ and viscosity, η of D(+) galactose and D(+) lactose mono hydrate (0.00, 0.02,0.03,0.05,0.07 & 0.08)M in aqueous solution of sodium butyrate(0.00,0.03,0.05,0.08 & 0.10) M solutions have been determined experimentally at 308K.From these experimental data a number of thermodynamic parameters namely, apparent molalvolume фv partial molalvolume ф0v, transfer molalvolume, ∆фtr0at infinite dilution and experimental slopes Sv,A and B coefficients respectively have been calculated. These parameters were utilized to study various interactions taking place in the solutions of D(+) galactose and D(+) lactose mono hydrates in aqueous solution of sodium butyrate the study of interaction between them at 308 K
