Muscles, ligaments, tendons, and various organs, glands, nails, hair, enzymes, hormones – are made up of proteins that are also needed for bone growth. Amino acids are chemical components of protein molecules. Various combinations of the 28 known amino acids in our bodies form a 50 000 different proteins and 20,000 enzymes. The human body can synthesize any desired protein of the 28 amino acids. The number of combinations exceeds all imagination – more than 10 to the 130th degree! Each amino acid is an amino containing, among other things, nitrogen. In the absence or insufficient amount to at least one amino acid necessary proteins are formed. Amino acids are precursors of neurotransmitters or neurotransmitters – the transmitters of nerve impulses in sipansah – ie participate in the central nervous system, allowing it to receive and send signals. Obviously, 80% of amino acids are synthesized in the liver and the rest we get from food.
In humans, the essential distinction, conditionally essential and nonessential amino acids. Essential are those that are not synthesized by the body or are synthesized in minute amounts. We get them daily with food. Conditionally essential – those who, in a certain state metabolism, are not produced in sufficient quantities. Replaceable – all the rest.
The body produces enough of them, in the presence of nitrogen from essential amino acids. Individual amino acids linked together in chain, called di-, tri-, … polypeptides. Of these chains are proteins. Essential amino group: isoleucine, leucine, lysine, methionine, federal Nila-nin, threonine, tryptophan, valine.
