Amino acids, both those which the body is able to produce itself, as well as those which cannot be synthesized, are the essence of life. Not for nothing they are called the building blocks of the body as they have influence on a number of very important and essential functions. Amino acids are so varied that they can take effect both for whole systems, as well as various cell organelles. Their task is not only to increase anabolism and reduction of catabolism, which are the most recognizable processes among working out people. Amino acids also perform the following functions: transport, regulatory, recovery, purifying, transferring, energetic and the production of metabolically active compounds.
