Metabolism

Political changes are constantly taking place. The distribution of cells and tissues and their reconstruction is constant. These processes should be accompanied by a balance between the demand of the system and the nutrients supplied. Excess energy ingredients lead to obesity, deficiency to lower body weight.

Table 1

Medium chemical composition of the body of an adult

From the table list 1 can be seen, that the variety of ingredients is large. All these ingredients or material for their construction must be supplied with food. So food must be similar to the composition of human tissues.

There are several dozen nutrients in the products. The most important one includes about 20 amino acids, from which proteins are built, several types of carbohydrates, fatty acids included in fats and several minerals and vitamins.

The food also includes various fragrances, dyes etc..

The human body can produce some of these substances from the material given in a different form, np. Fat can be synthesized from carbohydrates or the non -inclined part of the amino acids. Others must be in a ready form. Therefore, there is a division of ingredients into endogenous - these, which arise in the system and exogenous - which do not arise in the human body. So man must, from exogenous ingredients, primarily receive all minerals, Most vitamins, Some amino acids and fatty acids. However, you must not forget, that all ingredients are equal to the body and are not more or less important. The differences occur only in the speed of the harmful deficiency of some ingredient. Deficiencies of these ingredients are at the latest, which the body accumulates in the form of stocks, e.g.. vitamins, and the fastest these, which are used at a given stage of the body's development for particularly intense changes, e.g.. Lack of vitamin D in children manifested in curvature,* or the lack of vitamin C manifested in the states of apathy and gum bleeding.

The relationships between individual ingredients are drawn at every step. For example, incorrect calcium ratio to phosphorus promotes the formation of rickets despite sufficient delivery of vitamin D (and vice versa). Lowering the amount of protein in the diet can lead to anemia, but even a sufficient amount of protein with too little iron can also lead to hemoglobin deficiency. It is worth adding an example chain of interdependencies to this, that a sufficient amount of protein and iron does not guarantee the formation of the right amount of hemoglobin when there is no copper, which works in the synthesis of hemoglobin. Iron, What is worth emphasizing, It is better absorbed in the presence of ascorbic acid (vitamin C), so this component is significantly intermediate, affects the course of hematopoietic processes.

Only from the given example can be seen, that there could be no answer to the question, Which of the diet components is the most important.

So let's emphasize again, that metabolism (metabolism), So life, it depends on the correct, full and conscious delivery of appropriate ingredients with food.

A characteristic feature of metabolism is the constant exchange of ingredients found in the system with ingredients taken from food. Both the processes of decay and synthesis are accompanied by energy changes. Usually, energy is triggered in the decay processes, which is largely used for synthesis reactions.
