**''Glycogen'' is synthesised in the liver and 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 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.

**The energy release is used to transport glucose and galactose up their concentration gradients into the enterocyte.

**Glucose and galactose can then diffuse into the blood (portal vein) by carrier mediated diffusion via a GLUT-5 transporter.
