Sub Topic Name : Structure Of Glucose |
1.Glucose is an aldohexose and is also known as dextrose. 2.It is the monomer of many of the larger carbohydrates, namely starch, cellulose. 3.It is probably the most abundant organic compound on earth. 4.Its molecular formula was found to be C6H12O6. 5.On prolonged heating with HI, it forms n-hexane, suggesting that all the six carbon atoms are linked in a straight chain. 6.Glucose reacts with hydroxylamine to form an oxime and adds a molecule of hydrogen cyanide to give cyanohydrin. 7.These reactions confirm the presence of a carbonyl group (>C = O) in glucose. 8.Glucose gets oxidized to six carbon carboxylic acid (gluconic acid) on reaction with a mild oxidizing agent like bromine water. 9.This indicates that the carbonyl group is present as an aldehydic group. 10.Glucose is correctly named as D(+)-glucose. 11.‘D’ before the name of glucose represents the configuration. 12.‘(+)’ represents dextrorotatory nature of the molecule.
Elements, sugar, organic molecule
There are many different types of important carbohydrates, ex: glucose, sucrose, lactose etc.
