Because they have the same formula, glucose's α and β anomers share many properties, such as their solubility in water, heat of combustion, and ability to reduce certain compounds. Other properties are different, however. For example, α glucose rotates polarized 589 nm light more than β glucose.
Click on the image to switch the configuration of C1. Then click on the Close Ring button to see which anomer is formed from that configuration. The paper and molecular structures of the product are shown in a similar orientation, with C1 toward the right. Notice how only the direction of the hydroxyl group on C1 is different.
