Sorption of L-proline by monocarboxy cellulose from aqueous solutions was s
tudied under static conditions at 293 +/- 1 K and pH approximate to 6. It w
as established that the sorption of L-proline increases sharply at equilibr
ium concentrations above 6 x 10(-2) M. As a result, "overloading" of amino
acid arises rapidly in the cellulose phase; based on this effect, a macromo
lecular therapeutic monocarboxy cellulose-proline system can be developed.
