1,4 glycosidic bond
Glycosidic bonds are formed due to a condensation reaction between two monosaccharides to form a polysaccharide. A condensation reaction is when two molecules combine to create a simple molecule and water is eliminated.
The 1,4 glycosidic bond is formed between the carbon- 1 of one monosaccharide and carbon-4 of the other. There are are two types- 1,4 alpha and 1,4 beta glycosidic bonds. 1,4 alpha glycosidic bonds are formed when the OH on the carbon- 1 is below the glucose ring; while 1,4 beta glycosidic bonds are formed when the OH is above the plane.
