Many common preparatory sources use g/mol and effectively define it as a synonym of molar mass, while more authoritative sources use Da or u and align its definition more closely with the molecular mass. The purified protein component was recognized that it was bluish green protein containing copper and zinc, and its molecular weight was 25,700. This protein component had no effect on the metabolism of drugs by liver microsomes but showed specific activation of hydroxylation of 2-aminobenzoyl compounds. However, native hemicelluloses are usually unable to form strong and durable films due to their short chain (low molecular weight), high hydrophilicity, and heterogeneous nature. Galactoglucomannan is the major hemicellulose in process water from thermomechanical pulping of spruce.

Galactoglucomannan molecular weight

Empirical Formula (Hill Notation): C24H32O4S. Molecular Weight: 416.57. The galactoglucomannan from southern pine had a molar ratio of 1:1:3 galactose glucose mannose. Light, scattering and intrinsic viscosity measurements were made in water and in alkaline borate. The molecular weight and viscosity in water were 63,800 and 0.48 dl./g., and in borate solvent, 27,600 and 0.27 dl./g., respectively, indicating that aggregation is present in water. A galactoglucomannan (GGM) has been purified from the primary cell walls of ripe kiwifruit.

Polymers mainly consisting of galactoglucomannan with an average molecular weight of 30 kDa were extracted from fiberized wood with water.Different Nearly 6 mg/g wood of galactoglucomannan was obtained at 90 °C/120 min which was about three times more than what could be extracted from wood chips.
