Carbohydrates

Carbohydrates are the components in foods that are a major source of energy for living organisms. In our food, there is a polysaccharide carbohydrate that is made in plants by photosynthesis. In the process of digestion, carbohydrates undergo a process of hydrolysis, both in the mouth, stomach and intestines. The end result of this process of carbohydrate digestion is glucose, fructose, galactose and other monosaccharides matosa as well. In the cells of the body, carbohydrates are experiencing a variety of chemical processes.It is this process which has an important role in our body.Chemical reactions that occur in these cells does not stand alone but are interrelated and influence each other.In previous sections you have studied a wide range of carbohydrates, including monosaccharides, disaccharides, oligosaccharides and polysaccharides. Carbohydrates are ready dikatabolisir into energy if the form monosaccharides. The energy generated in the form of Adenosine triphosphate (ATP).
Glucose is the most important carbohydrates. In the form of mass glukosalah carbohydrate foods are absorbed into the blood stream, or into a form glukosalah carbohydrates are converted in the liver, as well as from glukosalah all other forms of carbohydrates in the body can be formed. Glucose is the major metabolic fuel for the tissues of mammals (except ruminants) and the universal fuel for the fetus. This element is converted into other carbohydrates with very specific functions, such as glycogen for storage, in the form of ribose nucleic acid, galactose in milk lactose, in particular complex lipid compounds and in combination with proteins, ie glycoproteins and proteoglycans

Overview of metabolism
Events experienced by the elements of the food is digested and absorbed after the intermediate metabolism. So metabolic intermediate cover a broad field that seeks to understand not only the metabolic trajectory experienced by each molecule, but also the interrelationships and mechanisms that regulate the flow of metabolites through the path.
Panorama of metabolism can be classified into 3 categories:
1. Panorama of anabolic (union / formation)
This is the path used in the synthesis of compounds forming the structure and machinery of the body. One example of this category is the synthesis of proteins.
2. Panorama of catabolic (breakdown)
This trajectory includes various oxidation processes that release free energy, usually in the form of high energy phosphates or reducing equivalent elements, such as respiration chain and oxidative phosphorylation.
3. Amfibolik trajectories (crossing)
This trajectory has more than one function and there is at the intersection of metabolism so that it works as a liaison between the trajectory of anabolic and catabolic path. An example of this trajectory is the citric acid cycle
