Definition of beta-glucose rotation
Check what you remember
Read the wording for your board, then hide it and explain beta-glucose rotation in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Alternate beta-glucose molecules must be rotated through 180 degrees before their hydroxyl groups align and the bond can form, producing the straight cellulose chain.
