**There are two types of starch, ''amylose'' which has α1-4 glycosidic links and, ''amylopectin'' which has α1-4 glycosidic links and α1-6 glycosidic links making it branched (branches every glucose 25 residues).

**''Glycogen'' is synthesised in the [[Liver - Anatomy & Physiology|liver]] and [[Muscles - Anatomy & Physiology|muscle]] and is similar to amylopectin as it has both α1-4 glycosidic links and α1-6 glycosidic links. However it is more highly branched with shorter branches (branches every 12-18 glucose residues).

*The '''first stage''' of carbohydrate digestion begins with α-amylase, which is an endoglycosidase. ''(This means it breaks bonds in the middle of the polymer to produce di-, tri- and oligo-saccarides).''

*α-Amylase is present in [[Oral Cavity - Salivary Glands - Anatomy & Physiology|saliva]]. Salivary α-amylase is inactivated when it enters the [[Forestomach - Anatomy & Physiology|stomach]] due to it's acidic pH.

*Carbohydrate digestion continues in the lumen of the [[Small Intestine - Anatomy & Physiology|small intestine]] as pancreatic α-amylase enters the [[Duodenum - Anatomy & Physiology|duodenum]] in the pancreatic duct. This is the site of the majority of carbohydrate digestion.
