Carboxy methyl cellulose (CMC)or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to
some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium
salt, Sodium Carboxymethyl Cellulose.
It is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl
groups render the cellulose soluble and chemically reactive. The functional properties of CMC depend on the degree of
substitution of the cellulose structure (i.e., how many of the hydroxyl groups have taken part in the substitution reaction),
as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl
substituents http://www.ytfoodchem.com/
