The carbonyl compounds of organic substrates such as aldehydes, acids and ketones
are very important in chemical industry owing to its wide applications in medicine and
pharmaceutical purposes. Therefore, chemists have been focused a great attention for
synthesis of such carbonyl compounds using different techniques. The most efficient
method used for such purpose is the oxidation of the corresponding alcoholic substrates
with a suitable oxidizing agent such as chromic acid, permanganate ion and cerium (IV)
oxidants owing to the high potential values of the redox couples in their redox systems.
Although, the natural occurring water-soluble macromolecules such as
polysaccharides involving both carrageenans and chondroitin as sulfated macromolecules
are of great importance owing to its wide applications in industrial technology
particularly in the medicine, pharmacy and food industry, a little attention has been
focused on their oxidation kinetics despite the presence of a lot of oxidizable moietiesfunctional
groups within the monomers of their macromolecular chains. This fact may be
