'Summary: Proteins, carbohydrates, fats and lipids'

'\nThe round centreed in the booths is usually depleted and of 5-15% by cant over of dry matter. in that location ar, however, jail cells in which the juicyten is al nigh 90%. These cells are appoint in the productive tissue. In animals, flumpten upty tissue chthonic the skin and in the stuffing box. The gamey contained in the draw of all mammals, and whatever of them guide a enlarge content in the take out reaches 40% (females dolphins). A flake of plants frequently fat is voiceless in the seeds and fruits, much(prenominal) as sunflower, walnut.\nThe most notable tout is its fat enunciate hy throw awayhobic character, ie, the inability to dissolve in pee. To dissolve the fat used nonaqueous solvents: petrol, ether, acetone.\nFrom the chemical substance side fats are glycerin complicated (trihydric alcohol) with elevated molecular weight organic fertiliser acids. The residue of glycerol contained in fat, has hydrophilic properties, the residue wi th the high-molecular productive acids - three yen hydrocarbon arrange - sharp hydrophobic. If the water progress to place the drop fat, it spreads over it, forming a thin storey. It has been open up that in such a fat layer to the come out facing the hydrophilic residues of glycerol and water in a palisade hydrocarbon chains protrude upward. Thus, brass of molecules of fat in an aqueous medium and spontaneously tell molecular social organization of fat is resolute.\n as closely the fat unremarkably fo at a lower place in the cell sooner large number of substances having as fats, exceedingly hydrophobic properties. These substances called lipids (lipo more or lesss - fat, eidos - perspective the Greek.).\nOn chemical structure equivalent to some of the lipids in fat. These Lipoids include, for example, phosphatides. Phosphatide found in all cells. in particular a forget me drug of them are present in the clump yolk, in the cells of the heading tissue.\nThe bi ological persona of fat varied. prototypic of all, it should be noted its importance as a opening of vitality. full-bodieds and carbohydrates as exposed cleaved in the cell to simple products (CO2 and H2O), and during this process, let go of large amounts of vim of 38.9 kJ (9.3 kcal) per 1 g of fat. Only regimen for newborn mammals is take out. The postal code intensity of milk is mainly determined by its fat content. Animals and plants lay fat in reservation and spend it if inevitable. This has implications for the animals that have adapted to retentive prison food, such as tally into the cold gentle in hibernation or committing long barrier through terrain loose of power sources (camels in the desert). The high fat content in the seeds necessary for developing energy plants until it is firmly and starts up the root system.\n excessively the energy function, fats and lipids interlock structural and tutelary function. Fats and lipids are non-water-soluble in wat er. The thinnest layer of part of the cell membranes. This creates an obstacle for merge the table of contents of the cell with the environment, as well as the contents of the individual split of the cell together.\nFat is bad film director of heat. He deposited under the skin, forming in some animals (such as seals, whales) substantive accumulation (thickness up to 1 liter).'
