Oxygen Equivalent Caloric

Oxidation is the process by which a substance loses electrons and gains a positive charge. Oxidation occurs in all living organisms, as well as during chemical reactions.

Oxygen is one of the most important elements in our life, as it is necessary for breathing. Oxygen is involved in the oxidation process that occurs in the body's cells.

Caloric oxygen equivalent is the amount of heat released during the oxidation of one liter of oxygen. This is an important indicator for assessing the energy value of food.

To determine the caloric oxygen equivalent, it is necessary to conduct an experiment. A certain amount of product is placed in a test tube and oxygen is added. Then the amount of heat released is measured.

For example, if you place 100 g of meat in a test tube and add 1 liter of oxygen, then the amount of heat released will be equal to the caloric equivalent of oxygen for meat.

Thus, the caloric oxygen equivalent is an important indicator of the energy value of food products and allows us to assess their nutritional value.

The caloric equivalent of oxygen is the amount of heat that is released during the oxidation of a given substance when 1 liter of oxygen is inhaled in the air. Oxygen is considered as a necessary condition for metabolism in the human body. The process of enzymatic oxidation occurs in various tissues and organs of the body. Catabolic processes are a group of chemical reactions that regulate energy consumption and are accompanied by the intake and release of various products. Such products include thermal energy, urea, water, ATP, neuroprotective factor and other metabolites. These processes are high-energy because they require large amounts of ATP and associated chemical bonding. In addition, the process of enzymatic catalysis is carried out under the action of enzymes. At least one phosphorus derivative is required to activate and ensure the physiological function of enzyme molecules. The catalytic activity of enzymes is determined by the relationship between phosphorylation and dephosphorylation, as well as the number and nature of enzymes that react. The enzymes that initiate the reaction mechanism come into conflict from a few microseconds to several minutes. For some enzymes, the reaction time is nanoseconds. Quantitatively, the evolution of the process potential is determined by its main characteristic - the rate constant. Over time, from the emergence of a new protein product in the cell, a full number of new bonds are formed
