MetaCyc Compound Class: carboxymethyl cellulose

Synonyms: cellulose gum, CMC, E466, carboxymethylcellulose

Superclasses: all carbohydrates a carbohydrate a glycan a polysaccharide

Summary:
Carboxymethylcellulose (CMC) is a cellulose derivative with carboxymethyl groups 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. Unlike unmodified cellulose, carboxymethylcellulose is soluble in water.

CMC is used in food science as a viscosity modifier or thickener, and to stabilize emulsions in various products including ice cream. It is also a constituent of many non-food products, such as K-Y Jelly, toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing and various paper products.

SMILES: C([O-])(=O)COCC4(OC(OC1(C(OCC(=O)[O-])C(O)C(OC(CO)1)OC2(C(O)C(OCC(=O)[O-])C(OC(CO)2)OC3(C(O)C(O)C([R2])OC(COCC([O-])=O)3))))C(O)C(O)C([R1])4)

Reactions known to consume the compound:

Not in pathways:
a polysaccharide + H2O → an oligosaccharide

Reactions known to produce the compound:
