![]() Glucose can be altered to become different compounds by changing the orientation of the OH groups, in this case, to make galactose, or by having the carbonyl group in a different position, in this case, making fructose, thereby, making this a polyhydroxy ketone, which would also be called a ketose. In the center here, we have glucose, which is a polyhydroxy aldehyde, and consequently, it can also be called an aldose. Let's take a look at some structural formulas. A water molecule is removed, and the result is a hexagon whereby five carbo Ring-shaped glucose structures occur when the hydroxyl OH group on the carbon-6 atom reacts with the aldehyde group on the carbon-1 atom. Alpha-glucose is a form of glucose that is in a ring shape. The positioning of each of the four groups attached to them determines its overall three-dimensional shape in space. These four carbon atoms, C2 through C5, are called chiral carbons. For example, the four different groups carbon-2 is attached to include an aldehyde CHO group, a hydroxyl OH group, a hydrogen H atom, and a four-carbon CH(OH)CH(OH)CH(OH)CH2(OH) group. Carbon-2, carbon-3, carbon-4 and carbon-5 are each attached to four different groups: a hydrogen atom, a hydroxyl group, and two different types of carbon atoms. Carbon-1 is the carbon that is part of the aldehyde, or CHO group. As a straight chain, there are six carbon atoms, labeled from 1 to 6. Glucose is frequently written as a straight chain molecule. However, regardless of shape, all glucose molecules have 6 carbon atoms, and are single monosaccharides. The different shapes have different names. ![]() Some shapes occur naturally, others are the products of synthetic laboratory reactions. ![]() Glucose can exist in a variety of different molecular shapes, each one having unique properties. Glucose is a sugar molecule that can take many different forms in space.Photo Credit: utah778/iStock/Getty Images Alpha glucose is a specific isomer of glucose.

The glycosidic linkage 1->2 is found between an aldose and a ketose. In the alpha anomer of lactose, the second cyclized sugar is named _-_-_. In maltose, the first cyclized glucose is named alpha/beta-D/L- _. name a D-glucose cyclized into a beta anomer name a D-ribose cyclized into 5-sided ring as an alpha anomer A cyclized sugar will have an additional _ _ at C1 (compared to the linear structure). Where as (+) and (-) represent the direction of rotation of plane polarised light the ring. D says that the hydroxyl group is on the right side (In fischer projection). In the name D(+) Glucose, D represents the orientation of the hydroxyl group at the chiral carbon that is farthest from the highest oxidised carbon (Aldehyde group in this case) with respect to glyceraldehyde. Is alpha (D+) glucose same as beta (D-) glucose? No. Apart from catering students preparing for JEE Mains and NEET, PW also provides study material for each state board like Uttar Pradesh, Bihar, and others.Is Alpha (d+) Glucose Same As Beta (d-) Glucose?
