1)Carbon is attached to two hydrogens, an alcohol (OH), and a methyl group (CH3), then it's not a stereocenter because there are two hydrogens (which are the same unit). But if one of those hydrogens were changed into a carboxyl group (COOH), then it would be a stereocenter because all substituents are different.
The most abundant monosaccharide found in nature is in fact glucose. It is the most abundant organic compound on earth. We can find glucose in varies fruits, honey and even in starch and cane sugar. We obtain a large part of the energy in our bodies from glucose through the foods we eat. It is an aldohexose, which means it has six carbon atoms in its molecule. Its chemical formula is C6H12O6
We obtain glucose mainly from two sources which are starch and sucrose. Let us look at how we can prepare glucose from these sources
On a large and commercial scale glucose is prepared from hydrolysis of starch by boiling it with dilute H2SO4. The chemical reaction is as follows
(C6H10O5) + n (H2O) ————-> n ( C6H12O6 )
Starch Glucose
Also, another way of preparing glucose, with fructose as a joint or by-product, is to boil sucrose in dilute HCl or even H2SO4 in an alcoholic solution. This chemical reaction is as follows
C12H22O11 + H2O ————> C6H12O6 + C6H12O6
Sucrose Glucose + Fructose
