[Free amino acids in human blood serum during endogenous alimentation].

It has been ascertained that the blood serum of individuals fasting for 20 days demonstrates a sharply pronounced derangement in the proportions of amino acids, i. e. a manifestation of an endogenous amino acids imbalance. The most steep is the rise in the content of isoleucine, leucine and valine. These data may be used in considering issues concrened with an upset metabolism of amino acids under conditions of endogenous alimentation.
