The role of albumin
Albumin is the most abundant plasma, large molecular minimum, solubility, powerful function of a protein.
Plasma colloid osmotic pressure maintaining relies mainly on the plasma albumin, colloid osmotic pressure is to make the venous end the mainspring of interstitial fluid returning to the blood vessels.
When the plasma albumin decline caused by pathological conditions, the plasma colloid osmotic pressure drops, can lead to the excessive moisture into the tissue fluid in the blood and appear edema.
Plasma albumin transport function:
Plasma albumin can combine with many organic and inorganic ions in the body into a soluble compounds, become a form of transport of these substances in the blood circulation. Thus albumin belongs to the specificity of the transport proteins, on the physiological importance, is closely related to the health of human body.
Plasma albumin other physiological functions:
More than globulin, albumin in plasma content hydrophilic effect is bigger than globulin, the plasma albumin to globulin have a stable colloidal protection effect.Liver function damage will cause lack of albumin synthesis, will lead to the plasma globulin lose colloid protection, stability.In addition, the albumin is a kind of important nutrients in the body. Albumin in plasma is continually updated with metabolism, decomposition of amino acid, plasma albumin can be used in the synthesis of histones, oxidative decomposition in order to supply energy or into other nitrogenous substances.
Albumin is sticky, colloid substances, encountered heavy metal ions in the body, will be automatically combined with heavy metal ions, the excretory system eduction body outside, play the role of detoxification. Therefore, consumption of food containing rich albumin, can avoid the absorption of heavy metal ions and poisoning. Albumin and protection to the lining of the stomach.
Human blood albumin is one of the types of blood products, commonly known as the "product life", "life-saving medicine". The market price of 300 to 300 yuan a bottle. It is mainly used for clinical bleeding wounds and burns caused by shock, cerebral edema, and cirrhosis of the liver, kidney edema or ascites caused by such treatment of critical illness, and patients with hypoalbuminemia.
The role of liver function examination albumin In liver function tests, judging by examining the albumin of certain diseases. Different age paragraph the normal albumin were different, the scope of normal newborns albumin is 28 ~ 44 g/L, 14 normal range after albumin is 38 ~ 54 g/L, adults albumin normal range of 35 ~ 50 g/L, normal range after age 60 albumin is 34 ~ 48 g/L. In general, albumin increased mainly because of the blood concentration, such as severe dehydration and shock, severe burns, acute hemorrhage reduce adrenocortical function, chronic kidney disease. Albumin deficiency often because caused by liver cirrhosis and other liver diseases, such as malnutrition, chronic wasting disease, diabetes, kidney disease, etc. When the albumin is reduced to less than 25 g/L are prone to ascites.
