'''Peristáltico'''

Contracción antagonisticas de los músculos longitudinales ''y'' circulares. Transporte quimo por el intestino delgado, pero las contracciones pueden ser débil para que haya tiempo para la absorción. Cuando un ''onda'' peristáltica de contracción alcanza el final del [[Ileon - Anatomía & Fisiología|íleon]], otro comienza en el [[Duodeno - Anatomía & Fisiología|duodeno]]. Esto se conoce como un complejo ''mioeléctrica migrando''.

The main soluble carbohdrates found in food are starch, found mainly in plants, and glycogen, found mainly in animal meat. 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 [[Hígado - Anatomía & Fisiología|hígado]] and [[Muscles - Anatomía & Fisiología|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-saccharides).'' α-Amylase is present in [[:Categoría:Glándulas Salivales - Anatomía & Fisiología|saliva]]. Salivary α-amylase is inactivated when it enters the [[Estómago Monogástrico - Anatomía & Fisiología|stomach]] due to it's acidic pH.

Carbohydrate digestion continues in the lumen of the [[Intestino Delgado - Resumen - Anatomy & Physiology|intestino delgado]] as pancreatic α-amylase enters the [[Duodeno - Anatomía & Fisiología|duodeno]] in the pancreatic duct. This is the site of the majority of carbohydrate digestion. The '''second stage''' is the digestion of di-, tri-, and oligo-saccharides to monosaccharides. This is done by di-, tri-, and oligo-saccharidases which have a glycocalyx to trap their substrate. They are bound to enterocytes. The main dissacharides that are broken down are; Maltose into two glucose molecules, sucrose into a glucose and fructose molecule and lactose into a glucose and galactose molecule. These monomers can then be absorbed.
