Interpretation:
The structure of maltose should be drawn which is formed from two glucose monomers.
Concept introduction:
A biological molecule which consists of carbon, hydrogen and oxygen is known as saccharide or carbohydrate. The general formula of saccharide is
Saccharides (sugar) are classified as: monosaccharides, disaccharides and polysaccharides.
Monosaccharides are defined as a simpler carbohydrate which contains one sugar molecule and can’t ne hydrolysed into smaller carbohydrate.
Disaccharides are defined as a saccharide which contains two sugar molecules that is when two monosaccharides are linked by glycosidic bonds. It is a double ring structure.
Polysaccharides are defined as a saccharide which contains many units of sugar molecules that is more than two monosaccharides are linked by glycosidic bonds.
Explanation of Solution
Maltose consists of two units of monosaccharide. Two glucose molecules are combined with each other by glycosidic bond to form maltose.
The reaction is shown as:
According to the above reaction, two glucose molecules react with each other to form maltose with the formation of ether bond (ROR’) and removal of a water molecule.
Thus, the structure of maltose is:
