Digestion in the stomach is the process by which the food that we absorb changes its shape to one that our body is able to absorb. After certain physical phenomena and processes, as well as chemical reactions that are promoted by digestive juices, nutrients change so that the body can freely absorb them and then use them for metabolism. Digestion of food can occur while it moves through the organs of the gastrointestinal tract.
Various nutrients
The main components of a proper and healthy diet, scientists consider only three main classes of chemical compounds: proteins, carbohydrates (also sugar) and fats, namely lipids. Let's consider them in more detail.
Carbohydrates
These substances are present in the form of starch in plant foods. Digestion in the stomach and intestines contributes to the process of converting carbohydrates into glucose, and it, in turn, is stored in the form of glycogen, that is, a polymer, and is then used by the body. A single starch molecule is considered a very large polymer, which is formed from many glucose molecules. It is worth noting that raw starch is formed in granules. They must be destroyed in order to enable this substance to turn into glucose. It is cooking that contributes to the destruction of the granules of the starch contained in it.
You must also be aware that some foods contain carbohydrates in a special form of disaccharides. These are simple sugars, lactose, as well as sucrose, cane sugar. Digestion in the stomach turns these substances into even simpler compounds - monosaccharides, which do not really need to be digested.
Squirrels
They are represented by various polymers, which are formed from twenty different types of amino acids. After protein digestion , free amino acids form as final products. The intermediate products of the digestion of protein foods are polypeptides, peptones and dipeptides.
Fats
These are fairly simple compounds that, as a result of digestion and digestion, turn into fatty acids and glycerin.
Physical processes
Where is the stomach, we all know, but what physical processes occur in our body - not always. The basis of digestion is the grinding of food, which occurs during chewing and with rhythmic contractions of the intestines and stomach. Such effects help the food to grind and thoroughly mix all its particles with the digestive juices that are released in the intestines, stomach and mouth. Moreover, the reduction of the walls of the digestive tract ensures the constant advancement of food in its departments. All these movements are constantly regulated and controlled by the nervous system.
Chemical reactions
Digestion in the stomach cannot be imagined without chemical reactions within our body. Their basis is the breakdown of carbohydrates, fats and proteins, namely hydrolysis, which is carried out by a specific set of enzymes. Nutrients are broken down during hydrolysis into small particles that are absorbed in the body. This process is carried out quickly enough due to the effects of enzymes that are found in the gastric as well as other digestive juices.
Digestion is a rather complex process of food processing under the influence of physical processes and chemical reactions inside our body, which is associated with the breakdown of proteins, carbohydrates and fats into simpler substances. It is the compounds obtained as a result of digestion of food that are absorbed by our body.
