Amino acid determination

Amino acids are the basic unit of protein. There are 21 kinds of amino acids constituting human proteins, except for 脯 amino acids which are sub-amino acids, and other amino acids are α-amino acids. The amino acids constituting the protein molecule are all L-amino acids, but in recent years it has been confirmed that they can be isomeric as D-amino acids, and the specific mechanism has not been studied. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Clinically, the determination of serum or plasma amino acids, to avoid the effects of food digestion and absorption, should be taken in the early morning on an empty stomach. Specimens should not be used for hemolysis, so as to avoid false increases due to the entry of amino acids into the blood plasma. Normal value There are no specific standards, and there are different requirements for the content of essential amino acids in all ages, constitutions, and races. Clinical significance Different diseases will have different amino acid increases or decreases, such as: 1. Congenital amino acid metabolism abnormal diseases: (1) phenylketonuria: an increase in Phc; (2) citrullineemia: cit increases. 2, liver and kidney disease: (1) Severe hepatitis and cirrhosis: Phc, Try, and Mct increase, and Val, Icu, and Ilc decrease; (2) Renal insufficiency: non-essential amino acids increase, and essential amino acid Try decreases. Low results may be diseases: pediatric hepatic encephalopathy, pediatric protein-energy malnutrition, precautions for pediatric liver failure 1. Clinically, determine the amino acid of serum or plasma. To avoid the influence of digestion and absorption of food, blood should be taken on an empty stomach in the morning. 2, the specimen should not be used when hemolysis, so as not to cause false increase due to the amino acid in the red blood cells into the blood plasma. Inspection process The same amino acid is automatically analyzed and determined. Not suitable for the crowd no. Adverse reactions and risks no.
