It is likewise known together dextrose. The is referred to as aldohexose as it contains 6 carbon atoms and also an aldehyde group. It deserve to open in two forms, open-chain or ring structure. The is synthesized in the liver and kidneys of animals. In plants, that is uncovered in fruits and in different parts the plants. D- glucose is the normally occurring form of glucose. It can occur either in the hard or fluid form. The is water-soluble and also is also soluble in acetic acid. It is odourless and sweet to taste. In the year 1747, Andreas Marggraf a German chemist secluded glucose indigenous raisins. In the year 1838, Jean Baptiste Dumas coined words glucose.

Glucose have the right to be referred to as as aldohexose and dextrose. That is a monomer of countless larger compounds such together carbohydrates, starch, and cellulose. Top top earth, this is the most abundant essential compounds. On the basis of the following evidence it to be assigned the structure shown above:

It has a molecule formula that C6H12O6When hello is heated for a long time, n-hexane is formed which indicates that all the 6 carbon atom are attached in a straight chain.The oxime is developed when glucose reacts v hydroxylamine and cyanohydrins top top the enhancement of hydrogen cyanide come it. This reaction deserve to confirm the presence of the carbonyl group in glucose.The presence of -OH group is shown after the acetylation of glucose through acetic acid which gives glucose pentaacetate.Glucose and also gluconic mountain both returns dicarboxylic acid and also saccharic mountain on oxidation with nitric acid. The existence of major alcohol is suggested by this.

Preparation that Glucose (C6H12O6)

Sucrose (cane sugar) and also starch are the two major sources the Glucose.

Preparation indigenous sucrose or cane sugar:

Sucrose is a disaccharide v formula C12H22O11. On boil aqueous equipment 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 which as soon as boiled through dilute H2SO4 in ~ 393 K under 2 come 3 atmosphere pressure, provides glucose.

Uses the Glucose (C6H12O6)

It is provided in the treatment of hypoglycemia (low blood sugar)It is offered to patients that are an extremely sick and cannot eat together it gives carbohydrate caloriesIt is provided in the therapy of boosted potassium levels in the blood (hyperkalemia)It is supplied as a precursor because that the synthetic of substance.
