HUMAN NUTRITION

Detailed explanation-1: -Glucose, galactose, and fructose are all hexoses . They are structural isomers, meaning they have the same chemical formula (C6H12O6) but a different arrangement of atoms.

Detailed explanation-2: -Glucose, galactose, and fructose are monosaccharide isomers, which means they all have the same chemical formula but differ structurally and chemically. Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond.

Detailed explanation-3: -Although glucose, galactose, and fructose all have the same chemical formula (C6H12O6), they differ structurally and chemically (and are known as isomers) because of the different arrangement of functional groups around the asymmetric carbon; all of these monosaccharides have more than one asymmetric carbon (Figure3.2.

Detailed explanation-4: -As an example both glucose and fructose are hexoses (C6H12O6) but they have different chemical and physical properties. These types of compounds are called isomers.
