Proteins and amino acids, substratno for many enzymatic processes. Amino acids are not only structural elements of tissue specific proteins , but also act as neurotransmitters (glutamic and aspartic acid, glycine, etc.). The daily requirement for protein is 70 g. With a number of pathological conditions (including body temperature above 39 °C, heavy operations, burns, disorders of the processes of absorption in the digestive tract, etc.), it increases. In these cases, using proteins and mixtures of amino acids, albumin, dextran, Aminosol KE, Aminosteril, etc. (see SUBSTITUTES PLASMA, AND OTHER BLOOD COMPONENTS). Parenteral administration of proteins sencibilisiruet the body and can lead to anaphylactic reactions. They will not, if you use a mixture of individual amino acids (not formed antibodies). Better absorption of amino acids observed in/drip in the appointment, although if necessary it is possible their introduction through a tube into the stomach. For the full artificial nutrition proteins and amino acids are often complementary solutions of glucose, vitamins, trace elements etc.
