Because of this we have deducted 18 out of 150 and
have made the molecular weight of hemicellulose 132 which is taken for calculation
purpose. The other component of hemicellulose, arabinose again has a molecular formula
of C5H10O5 with molecular weight of 150. While glucose might be present in
hemicellulose the percentagewise it is not more than 15% so for simplicity of calculations
we have taken molecular weight of 132 of hemicellulose for the yields calculations.
