cells are called elementary unit of the structure of living organisms.All living beings - whether human beings, animals, plants, fungi or bacteria - basically have a cell.In someone's body these cells are many - hundreds of thousands of cells are the body of mammals and reptiles, and in someone's little - many bacteria are made up of just one cell.But it is not so important to the cell number as their availability.
long been known that cells have all the properties of the living: they breathe, eat, reproduce, adapt to new conditions, even dying.And, as in all living cells in the composition there are organic and inorganic substances.
inorganic substances much more, because the inorganic substances - this water, and minerals.Of course, the greatest part department entitled "inorganics cells" assigned to the water - it is 40-98% of the total cell volume.
water in the cell performs many important functions: it provides flexibility cells undergoing fast chemical reactions in it, travel agents arrived at the cell and their output.Furthermore, in many water soluble substances, it can participate in chemical reactions and that water is responsible for the temperature regulation of the whole body, since water has a good thermal conductivity.
addition of water, inorganic compounds and cells include many minerals, divisible by macrocells and microcells.
K macroelements are substances such as iron, nitrogen, potassium, magnesium, sodium, sulfur, carbon, phosphorus, calcium, and many others.
Micronutrients - is mostly heavy metals such as boron, manganese, bromine, copper, molybdenum, iodine, zinc.
Also there ultramicroelements body, including gold, uranium, mercury, radium, selenium, and others.
All inorganics own cells play an important role.Thus, nitrogen is involved in a great many compounds - both protein and non-protein promotes the formation of vitamins, amino acids, pigments.
Calcium is an antagonist of potassium serves as an adhesive to the plant cells.
molybdenum improves resistance of plants against fungi, parasites and accelerate protein synthesis.
Iron is involved in the breathing process, a part of the hemoglobin molecules.
Copper is responsible for the formation of blood cells, heart health and good appetite.
Boron is responsible for the growth process, especially in plants.
Potassium provides the colloidal properties of the cytoplasm, the formation of proteins and normal functioning of the heart.
Sodium also provides the right rhythm of the heart.
Sulfur is involved in the formation of certain amino acids.
Phosphorus participates in the formation of a huge number of essential compounds such as nucleotides, some enzymes, AMP, ATP, ADP.
Only ultramicroelements role is totally unknown.
But alone inorganic substances the cells are not able to make it a full and lively.The organic materials are important not less than them.
Organic substances include carbohydrates, lipids, enzymes, pigments, vitamins and hormones.
Carbohydrates are divided into monosaccharides, disaccharides, oligosaccharides and polysaccharides.Mono-, di- and polysaccharides are the main source of energy for the cells and the organism, but mixable with water oligosaccharides glued connective tissue and to protect cells from unfavorable external influences.
Lipids are divided into proper fats and lipids - fat-like substances, orient the molecular layers.
Enzymes are catalysts, accelerating the biochemical processes in the body.Furthermore, enzymes reduce the amount consumed per molecule reactivity imparting energy.
Vitamins are essential for the regulation of oxidation of carbohydrates and amino acids, as well as for proper growth and development.
hormones needed to regulate the functioning of the body.
