The primary hemicellulose in softwoods is O-acetyl-galactoglucomannan (GGM), representing approximately 20% of the dry weight. GGM consists of a backbone of β-(1 → 4)- d -mannopyranosyl and β-(1 → 4)- d -glucopyranosyl units decorated with single α-(1 → 6)-linked d -galactopyranosyl units attached solely to the mannopyranosyl units.

Chemically, guar gum is an exo-polysaccharide composed of the sugars galactose and mannose.[citation needed] The backbone is a linear chain of β 1,4-linked mannose residues to which galactose residues are 1,6-linked at every second mannose, forming short side-branches.

C to H, Root mean squared deviation (rmsd) of galactoglucomannan chains from its initial position on 36-chain cellulose surfaces. Formula weight (F.W.) is the sum of the atomic weights of all atoms in a given empirical formula. For example: sodium chloride (NaCl) has one atom of sodium (Na) and one atom of chlorine (Cl). The atomic weight of sodium is 22.99 g/mol and chlorine is 35.45 g/mol.
