Chemistry is one of the most important scientific sciences, and has diverse and useful topics and branches for human life. It plays an effective and indispensable role whether in agriculture, medicine, physics or inventions of various kinds. At the beginning of a simple and limited knowledge, due to the entry for the first time in the industry in particular in the conversion of cheap metals to precious metals and useful, and also for the first time in the world of medicine, especially in the pharmaceutical industry.
Chemistry includes many important branches, including medical chemistry, which is concerned with the manufacture of medical materials and tools used in laboratories and hospitals. Nuclear chemistry is the study of nuclear reactions and the production of nuclear materials, which are used in many fields such as the manufacture of weapons and nuclear bombs and hydrogen. Its branches also include pharmaceutical chemistry, which is related to the manufacture of various drugs and important therapeutic drugs. This development in the branches of chemistry is due to the efforts of various scientists, who seek in various ways and means to discover more scientific inventions that make fun of the benefit and service of man.
The fermentation process is defined as the process of chemical decomposition of organic materials which are due to the presence of microbes like bacteria, mold, yeast, and provide oxygen element, and represent the most widely used material sugars in the fermentation process, And produced some of the new elements of the fermentation process, and the most important of ethanol, lactic acid, hydrogen gas, and ethanol uses an element in the liquor industry, and it must be noted that the fermentation process may occur in the muscles of some mammals during intense exercise activities.
For this process a lot of benefits and damages, it benefits they are used in the production of penicillin process through the sugar union with some mineral salts, the presence of fungi and the atmosphere appropriate to provide the amount of oxygen, in addition to its entry in the wine industry and Alkhmuran by the decomposition of sugar due to soak some grain Kanb or barley in the water thereby producing alcohol and carbon dioxide by beneficial bacteria. But this process may be harmful when the milk ferments and becomes corrupt and harmful.
1-The second step is the conversion of pyruvic acid, depending on the cell type.
2-When oxygen is available, lactic acid is converted into pyruvic acid, but in the absence of oxygen, the pyruvic is converted into lactic acid.
