Partial molar volumes Vϕ0 and partial molar adiabatic compressibilities Kϕ,s0 of these amino acids at infinite dilution were evaluated. These values are required for calculating hydration number nH of amino acids. Transfer volumes ΔVϕ0 and transfer adiabatic compressibilities ΔKϕ,s0 at infinite dilution from water to aqueous sucrose solutions have been calculated. Transfer parameters have been discussed in terms of solute-cosolute interaction on the basis of a cosphere overlap model. Group contributions for the partial molar volumes and adiabatic compressibilities have been determined from the amino acids. All these results indicate that hydrophilic ionic group interactions are stronger than the hydrophilic-hydrophobic interactions in all the amino acids over the whole concentration range of sucrose solutions and decrease with the increase in size of side chain of amino acids. © 2004 Oldenbourg Wissenschaftsverlag GmbH Thermodynamics & statistical physics nationallicence Laboratory techniques, experiments nationallicence Physical chemistry nationallicence Pal Amalendu aut Kumar Suresh aut Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/10/2004(2004-10-01), 1169-1186 0942-9352 218:10/2004<1169 2004 218 zpch https://doi.org/10.1524/zpch.218.10.1169.43588 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zpch.218.10.1169.43588 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Pal Amalendu aut NATIONALLICENCE 700 1- Kumar Suresh aut NATIONALLICENCE 773 0- Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/10/2004(2004-10-01), 1169-1186 0942-9352 218:10/2004<1169 2004 218 zpch CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
