Absorption of sugars in the small intestine.. Sodium Screed Plant. Bilateral sugars. Single sugars. Glucose, galactose. Fructose

- 80% of sugars are absorbed in the duodenum and onset of fasting.
A) Absorption of plant screed:
• Plant polysaccharides form the predominant percentage of sugars in food.
• Sugar absorption is slow because it needs to work more until it is dismantled to:
- Cellulose is not absorbed in the human because of the absence of digestive enzymes.
- A starch that is transformed through the yeast of amylase (saliva and pancreas) into maltose, which in turn is converted by the maltase into two glucose molecules.
Note that the intestine absorbs only raw materials (monoclonal sugars).
B) absorption of double sugars:
• Fast absorption.
• Example:
حالب (لاكتوز) ← by lactase → galactose + glucose.
شون شون شون شون شون شون

.Maltose → Glucose + glucose.
Note: Maltose is not found in the food in the form of maltose but comes through starch.
C) absorption of monoclonal sugars:
• They are rare in the diet, found in fruits and honey.
• Fast absorption.
• Example:
- Glucose, galactose: absorbed effectively, depending on sodium, and there is a competition between the sugar on absorption.
- Fructose: It is absorbed by the diffusion mechanism.
- There are some sugars that are not absorbed: It is an indigestible sugar because of the lack of human to the yeast capable of digesting and dismantling and thus not absorb. Including: lactulose, which is given as a laxative in liver diseases to clean (rinse) and remove the residues of undigested proteins.
Lactolose sugar, as it is, reaches the small intestine and colon (without digestion or absorption), where it is fermented with fermentation. The fermentation process results in colloidal volatile substances (colic acids, organic acids). These substances cause dehydration ) Of the colon wall thus: Diarrhea - cleaning (rinsing).
 Thus, it is important to give such lactose (lactose) through the nasopharyngeal tube in some patients with the inhibition of consciousness due to cerebral hepatic impairment (in the patient of cirrhosis).
As a rule: sugars that are not absorbed: either because they were not digested or digested but not absorbed due to diseases of the intestines or pancreas, etc. - Intestinal fermentation process which may cause diarrhea.
Note: Laxatives are either non-absorbable (lactose) or non-absorbable salt (English salt).
