Main Difference – Glucose vs Galactose

Carbohydrates are the major components of all living organisms. Glucose and galactose are carbohydrates. Monosaccharides are the building blocks of larger carbohydrate molecules. The main difference between Glucose and Galactose is the position of each hydroxyl group in the 4th carbon; the position of hydroxyl group (-OH) in the 4th carbon is horizontal in the chair confirmation of the Glucose whereas the position of hydroxyl group (-OH) in the 4th carbon is upward in the chair confirmation of the Galactose.
