1,4 glycosidic bond
The 1,4 glycosidic bond is formed between the carbon-1 of one monosaccharide and carbon-4 of the other monosaccharide. There are are two types of glycosidic bonds - 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. When two alpha D-glucose molecules join together a more commonly occurring isomer of glucose compared to the L-glucose, form a glycosidic linkage, the term is known as a α-1,4-glycosidic bond.
