For example, the sugar molecule D-glucose has two common isomers in the cyclic form - alpha and beta. In water the molecule can open up into the straight. Dr. Sonya Rhodes developed this quiz over the course of many months to identify personality traits and relationship styles. Go through the statements below. (Exercises). • Basic Knowledge Practice Quizzes What is the term to describe the relationship between galactose and mannose?

Image modified from OpenStax Biology. As shown in the figure above, every other glucose monomer in the chain is flipped over in relation to its neighbors, and this results in long, straight, non-helical chains of cellulose. This gives cellulose its rigidity and high tensile strength, which are important to plant cells.

However, some herbivores, such as cows, koalas, buffalos, and horses, have specialized microbes that help them process cellulose. These microbes live in the digestive tract and break cellulose down into glucose monomers that can be used by the animal. Wood-chewing termites also break down cellulose with the help of microorganisms that live in their guts.

The bee's exoskeleton hard outer shell contains chitin, which is made out of modified glucose units that have a nitrogenous functional group attached to them. Cellulose is specific to plants, but polysaccharides also play an important structural role in non-plant species. I try to intuit other people's feelings. I am very competitive.

Alpha and beta glucose are isomers of each other but have different specific rotations Now, recall that each molecule in fact each isomer of a molecule will rotate plane polarized light to a specific degree, and this is called the specific rotation.
This means that alpha-D-Glucose will rotate plane polarized light at a different rotation than beta-D-Glucose will rotate it. Mutarotation Okay, now that we have reviewed a bit of background knowledge, let's learn about mutarotation.
Mutarotation refers to the change in specific rotation over time due to a change between isomers. The specific rotation of a molecule never changes, but the specific rotation of the entire solution can change. This is because the molecule can change between isomers in some cases such as with glucose. Example Let's look at what happens when we put pure alpha-D-Glucose into water and measure the specific rotation over time.
