You may be looking for albumen, or egg white. Albumen redirects here. ...


Albumin is a blood plasma protein that is produced in the liver and forms a large proportion of all plasma protein. It is also found in egg white. Blood plasma is a component of blood. ... A representation of the 3D structure of myoglobin, showing coloured alpha helices. ... The liver is an organ in vertebrates including humans. ... Albumen redirects here. ...


The normal range of albumin concentrations in human blood is 3.5 to 5.0 g/dL, and albumin normally constitutes about 60% of plasma protein; all other proteins present in blood plasma are referred to collectively as globulin. Albumin is essential for maintaining the oncotic pressure needed for proper distribution of body fluids between intravascular compartments and body tissues. Albumin is negatively charged. The glomerular basement membrane is also negatively charged, this prevents the filtration of albumin in the urine. In nephrotic syndrome, this property is lost, and there is more albumin loss in the urine. In health-related fields, a reference range is a set of values of some measurement that a physician or other health professional can use to interpret a set of results for a particular patient. ... Human beings are defined variously in biological, spiritual, and cultural terms, or in combinations thereof. ... A globular protein is a protein that is globe-like, or rounded in shape, often soluble in aqueous solution. ... In blood plasma, the dissolved compounds have an osmotic pressure. ... Bodily fluids are fluids, which are generally excreted or secreted from the human body. ...


Because smaller animals (for example rats) function at a lower blood pressure, they need less oncotic pressure to balance this, and thus need less albumin to maintain proper fluid distribution. This is an article about wild rats; for pet rats, see Fancy rat Species 50 species; see text *Several subfamilies of Muroids include animals called rats. ... Blood pressure is the pressure exerted by the blood on the walls of the blood vessels. ...


Functions of albumin:

  • Maintains oncotic pressure
  • Transports thyroid hormones
  • Transports other hormones, particularly fat soluble ones
  • Transports fatty acids ("free" fatty acids)
  • Transports unconjugated bilirubin
  • Transports many drugs
  • Competitively binds calcium ions (Ca2+)
  • Buffers pH

Causes of albumin deficiency: Hormone is also the NATO reporting name for the Soviet/Russian Kamov Ka-25 military helicopter. ... Bilirubin is a yellow breakdown product of haem (heme in American English). ... Many drugs are provided in tablet form. ... See also Calcium, New York, United States. ... PH or ph or pH or Ph may be: In chemistry, pH is a measure of acidity. ...

  • Cirrhosis of the liver (most commonly)
  • Decreased production (as in starvation)
  • Excess excretion by the kidneys (as in nephrotic syndrome)
  • Excess loss in bowel (protein losing enteropathy)
  • Mutation causing albuminemia (very rare)

Cirrhosis is a chronic disease of the liver in which liver tissue is replaced by connective tissue, resulting in the loss of liver function. ... Kidneys viewed from behind with spine removed The kidneys are bean-shaped excretory organs in vertebrates. ... Nephrotic syndrome is a disorder where the kidneys have been damaged, causing them to leak protein from the blood into the urine. ...

Albumin is the protein of the highest concentration in plasma.
Albumin transports many small molecules in the blood (for example, bilirubin, calcium, progesterone, and drugs).
Because albumin is synthesized by the liver, decreased serum albumin may result from liver disease.
