Truck Ratings for RV Towing. Quite a few options exist for towing a recreational vehicle, but four truck brands dominate the U.S. market: Chevrolet, Dodge, Ford, and GMC.
The linear form of glucose shown above makes up less than 3% of the glucose molecules in a water solution. The rest is one of two cyclic forms of glucose formed when the hydroxyl group on carbon 5 (C5) bonds to the aldehyde carbon 1 (C1), as shown below.
When beta-glucose molecules are joined to form a polymer cellulose is formed. Starch: Alpha glucose is the monomer unit in starch. As a result of the bond angles in the alpha acetal linkage, starch (amylose) actually forms a spiral structure. Cellulose: Beta glucose is the monomer unit in cellulose. As a result of the bond angles in the beta acetal linkage, cellulose is mostly a linear chain.
