By anabolism - are defined biosynthetic processes occurring in the living body i.e. the creating of complex constituents of the body, while retaining the necessary ATP level as an energy source (it is endogenic). Accordingly, the anabolic metabolism are involved in the formation of new tissues (in the entire human body), as well as in the regeneration. Synthesis of the amino acids of muscle proteins, fatty acid synthesis, and glycogenesis (glycogen synthesis) are classified as part of this changes among the others. Energy conversion - anabolism and catabolism - are in dynamic balance the body .
Anabolic transformations intensify during period of children and young people development as well as during the athletes recovery. Anabolic hormones are: estrogens, growth hormone, insulin, testosterone.
As the colloquial term "anabolic" refers to the synthesis of muscle protein.
