Disaccharides are formed when two monosaccharides combine together through a chemical process called the condensation. Disaccharides are known as complex sugar. Examples of disaccharides are, Maltose  known as malt sugar.  It is a reducing sugar It is formed from condensation of two glucose molecules.Glucose + glucose → maltose + water  Found in germinating cereals Produced during digestion … Read more

Monosacharides are monomers of carbohydrates.  Examples of monosacharides are: Glucose — found in plants and animals (It is the energy source for cellular respiration) Fructose — found in fruits and honey Galactose — present in milk They are reducing sugars, they can remove oxygen from other compounds.. They can be detected by using Fehling’s or … Read more
