WebThe alpha bonds of carbohydrates are broken down during digestion by specific enzymes. Lactose contains a beta bond, which is digestible by lactase. Most carbohydrates that contain beta-glycosidic bonds are not digestible because humans lack the enzyme needed to break down the bond. A glycosidic bond or glycosidic linkage is a type of ether bond that joins a carbohydrate (sugar) molecule to another group, which may or may not be another carbohydrate. A glycosidic bond is formed between the hemiacetal or hemiketal group of a saccharide (or a molecule derived from a … See more Glycosidic bonds of the form discussed above are known as O-glycosidic bonds, in reference to the glycosidic oxygen that links the glycoside to the aglycone or reducing end sugar.
