WebJan 21, 2016 · The chiral centres are the carbon atoms with four different groups attached. There are no internal mirror images, so every carbon atom is different. The chiral centres in sucrose are. Carbons 1,2,3,4,5 in the glucose unit. Carbons 2,3,4,5 in the fructose unit. That makes a total of nine chiral centres in sucrose.

WebFuranose. A furanose is a collective term for carbohydrates that have a chemical structure that includes a five-membered ring system consisting of four carbon atoms and one oxygen atom. The name derives from its similarity to the oxygen heterocycle furan, but the furanose ring does not have double bonds. [1] WebCorrect option is A) A chiral carbon is defined as a carbon atom which has 4 different atoms or groups of atoms attached to it which is also known as an asymmetric carbon.
