Novel Synthesis of Diketopectate Coordination Biopolymer Derivatives as Alternative Promising In Biomedicine, Pharmaceutics and Food Industrial Applications

Abstract

Diketopectates (PDK) was quantitatively synthesized by the oxidation of pectin sol with potassium permanganate in alkaline solutions at pH`s > 12. The yield was 97.3 %. The chemical structure of such synthesized pectate-diketones was elucidated by elemental analysis and spectroscopic data. Sol-gel transformation and/or precipitation were observed when PDK was added to polyvalent metal ion electrolytes. The reaction mechanism of synthesis process was suggested and discussed.
