Albumin

Definition

noun, plural: albumins

(1) (biochemistry) The water-soluble protein found in egg white, blood, lymph, tissues and other fluids.

(2) The major plasma protein responsible for the plasma colloidal osmotic pressure. Its role is to transport protein carrying large organic anions (e.g. fatty acids, bilirubin, and many drugs), certain hormones (e.g. cortisol and thyroxine), when the specific binding globulins are saturated.


Supplement

The serum albumin is synthesized in the liver. Low serum levels occur in protein malnutrition, active inflammation and serious hepatic and renal disease.


Word origin: Latin albūmen, from albus, white

Variant: albumen

SDS-PAGE

... mass protein ladder. in our book we have a picture of a ladder starting from 10kD up till 250kD and next to it it has a bunch of proteins such as albumin from bovie 66000Da and Trypsin Inhibitor from soybean 20100Da. It then goes on to say make a plot of log (molecular weight) against relative ...

Renal

There are a couple of possible answers here. My guess: The osmolarity of blood is fairly constant, adjusted by serum albumin, which is a protein. The more albumin, the more total protein, which adds to the non-filterable particles in the blood. The proteins also hold onto more water, ...
