Glucose is a simple sugar with six carbon atoms and one aldehyde group. This monosaccharide has a chemical formula C6H12O6. It is also known as dextrose. It is referred to as aldohexose as it contains 6 carbon atoms and an aldehyde group. It exists in two forms, open-chain or ring structure. It is synthesized in the liver and kidneys of animals. In plants, it is found in fruits and in different parts of plants. D- glucose is the naturally occurring form of glucose. It can occur either in solid or liquid form. It is water-soluble and is also soluble in acetic acid. It is odourless and sweet to taste. In the year 1747, Andreas Marggraf, a German chemist, isolated glucose from raisins. In the year 1838, Jean Baptiste Dumas coined the word glucose. Properties of Glucose – C6H12O6
Glucose can be called as aldohexose as well as dextrose. It is a monomer of many larger compounds such as carbohydrates, starch, and cellulose. On earth, this is the most abundant organic compound. On the basis of the following evidence, it was assigned the structure illustrated above:
Preparation Of Glucose (C6H12O6)Sucrose (cane sugar) and starch are the two major sources of Glucose. Preparation from sucrose or cane sugar: Sucrose is a disaccharide with the formula C12H22O11. On boiling an aqueous solution of sucrose with dilute HCl or dilute H2SO4, Glucose and Fructose are formed in equimolar proportions. C12H22O11 + H2O → C6H12O6 + C6H12O6 Sucrose Glucose Fructose Preparation from starch: It is a polysaccharide that when boiled with dilute H2SO4 at 393 K under 2 to 3 atmosphere pressure, gives glucose. ( C6H12O5)n + n H2O → nC6H12O6 Starch Glucose Uses Of Glucose (C6H12O6)
The chemical formula of Glucose is C6H12O6. Glucose is a monosaccharide containing an aldehyde group (-CHO). It is made of 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. Glucose is an aldohexose.
Glucose is a reducing sugar because it belongs to the category of an aldose meaning its open-chain form contains an aldehyde group. Generally, an aldehyde is quite easily oxidized to carboxylic acids.
The 5 reducing sugars are ribose, glucose, galactose, glyceraldehyde, xylose.
Glucose consists of three elements such as carbon, hydrogen and oxygen. 6 carbon atoms bonded together as a chain with additional atoms of oxygen and hydrogen.
Glucose is a monosaccharides sugar. It occurs in the free state in the ripe grapes ( grape sugar) in honey and also many sweet fruits. Glucose is an essential constituent of human blood which normally contains 65 mg to 110 mg of glucose per 100 mL. It is named as blood sugar.
