Hydrocarbons with the formula (C6 H12 O6) are chemical compounds composed of carbon, hydrogen and oxygen. The main constituents of hydrocarbons are monosaccharides. They contain series of carbon atoms in the molecular chain along with oxygen and hydrogen atoms, while hydrocarbons forming glucose do not remain in nature in large quantities. Hydrocarbons with complex polymeric molecules by losing their water are abundant in nature. Hydrocarbons are present in the form of starch in plants and glycogen in animals. Starch and glycogen in the vicinity of water are easily converted into glucose when needed. Starch glycogen stored in animals (especially in the liver and muscles) is converted into glucose and enters the blood if the blood sugar level drops to the minimum necessary. Fresh mushrooms contain enough hydrocarbons and vegetable fiber. Button mushroom contains pantoses, hexoses, disaccharides, amino acids, as well as unknown uronoids and butyl sugars. Among polymeric hydrocarbons, glycogen and chitin are polymers of acetylglycosamine-N (Acetylgyeosamine-N) as the structural composition of mushroom cell walls. In young specimens, there is a large amount of E. trehalose (fungus), which is hydrolyzed into glucose as soon as the fungus reaches maturity.
