Short Bowel Syndrome (SBS) is when the intestines do not absorb nutrients properly. This can occur due to intestinal disease or when part of the small intestine is missing from either a genetic defect or surgical removal. Most overlook the un-named intestinal disease contribution to Short Bowel Syndrome considering it only with a named intestinal disease, i.e. Celiac, Crohn’s, or IBS. Chelation therapy poisons the bowel lining causing not only SBS but also Barren Gut Syndrome (BGS). BGS occurs when the lining of the intestines is so damaged beneficial bacteria have no place to adhere to.

It can be hydrolyzed to form glucose, but not by the digestive enzymes in humans.

Denaturing the enzyme was very difficult. We had to boil the enzyme (placing a test tube with the enzyme in a beaker of boiling water) for thirty minutes.

Intercellular Digestion Extracellular digestion is when the breaking down of food into smaller absorbable particles takes place outside the cell.

Proteins Types of Proteins: Structural (hair, webs) Storage (seeds) Contractile (muscles) Transport (hemoglobin) Defensive (antibodies) Signal Enzymes (lactase)

Briefly stated, ingestion of protein foods causes a secretion of hydrochloric acid in the stomach, and hydrochloric acid destroys ptyalin; that is, it destroys the amylase activity and substitutes acid hydrolysis. Physiology texts state that “if this acid hydrolysis was continued long enough it could reduce all the digestible carbohydrates to the monosaccharide stage. However, the stomach empties itself before this can take place.”

Have you heard the term 'lactose intolerant'

Children diagnosed with short bowel syndrome are also often slow in growth or development, due to lack of nutrition.

Cellulose is the fiber in the diet, but no human cell is known to produce a cellulase, an enzyme that breaks down fiber for digestion. Several species of bacteria in the large intestine produce cellulases and digest celluose. Importantly the major end products of microbial digestion of cellulose and other carbohydrates are volatile fatty acids, lactic acid, methane, hydrogen, carbon dioxide and hydrogen sulfide. Fermentation is the major source of intestinal gas.

Metabolism is the term used to describe the many chemical changes that occur after the end products of digestion have been absorbed into the body. There are two phases of metabolism: 1) anabolism, which is the chemical reaction by which absorbed nutrients are utilized for replacement of used or worn-out body substances (maintenance) and to create new cellular material (growth), and 2) catabolism, which includes the chemical reactions whereby cellular materials are broken down into smaller units. An example of anabolism is the use of monosaccharides to build up stores of muscle and liver glycogen, and an example of catabolism is the breaking down of these glycogen stores to supply energy to the muscles during physical exersion. Anabolism and catabolism occur simultaneously in the body cells.

To summarize this aspect of starch digestion, taking proteins, acids, water or other liquids with starches interferes seriously with their digestion by the salivary amylase, ptyalin. This first stage of starch digestion is of great importance because there is a great likelihood that the food will be acted upon by bacteria and ferment before it reaches the intestine where further starch digestion can take place. Digestion, rather than fermentation and its resulting toxic byproducts, is much more likely to occur soon after the food is put into the mouth than further along in the digestive tract.

A Description of Lactose and Lactase Reaction

These polypeptides are then moved into the small intestine for further digestion.
Digestion of Carbohydrates: The Mouth
Amyslase within saliva begins the breakdown of amylose found in starches (plant polysaccharides) into smaller glucose subunits that are easier to digest by the body.
Digestion of Carbohydrates: The Stomach
Carbohydrates enter the stomach and continue to be broken down by enzymes like Amylase, Lactase, and Invertase.

Absorption of glucose, galactose, fructose - Tuscany Diet

Fermentation is the digestive process by which carbohydrates are broken down by microorganisms into simple molecules for absorption into the bloodstream. Some fermentation takes place throughout the gastrointestinal tract, but the intensity of fermentation depends on microbial numbers, which are generally highest in the large intestine. Thus, the large intestine is quantitatively the most important site of fermentation, except for the species with forestomachs (ruminants like cows).

Absorption of glucose, galactose and ..

The enzymes break disaccharides and polysaccharides into monosaccharides such as glucose, fructose, and galactose through a process known as hydrolysis.

What your bowel movement will tell you about your health. The human gut is almost unique amongst mammals – the upper gut is a near sterile, digesting carnivorous gut (like a dog’s or cat’s) to deal with meat and fat, while the lower gut (large intestine) is full of bacteria and is a fermenting vegetarian gut (like a horse ‘s) to digest vegetables and fiber.
