albumin

(ălbyo͞o`mən) [Lat.,=white of egg], member of a class of water-soluble, heat-coagulating proteinsprotein,
any of the group of highly complex organic compounds found in all living cells and comprising the most abundant class of all biological molecules. Protein comprises approximately 50% of cellular dry weight.

. Albumins are widely distributed in plant and animal tissues, e.g., ovalbumin of egg, myogen of muscle, serum albumin of blood, lactalbumin of milk, legumelin of peas, and leucosin of wheat. Separation of serum albumins from other blood proteins can be carried out by electrophoresis or by fractional precipitation with various salts. Albumins normally constitute about 55% of the plasma proteins. They adhere chemically to various substances in the blood, e.g., amino acids, and thus play a role in their transport. Albumins and other proteins of the blood aid significantly in regulating the distribution of water and maintenance of proper osmotic pressure in the body. Albumins are also used in textile printing, in the fixation of dyes, in sugar refining, and in other important processes.

Albumin

A type of globular protein that is characterized by its solubility in water and in 50% saturated aqueous ammonium sulfate. Albumins are present in mammalian tissues, bacteria, molds, and plants, and in some foods. Serum albumin, which contains 584 amino acid residues, is the most abundant protein in human serum, and it performs two very important physiological functions. It is responsible for about 80% of the total osmotic regulation in blood, and it transports fatty acids from adipose tissue to muscle. When excessive amounts of albumin are found in the urine upon clinical examination, some form of kidney disease is usually indicated. Another important albumin, ovalbumin, is found in egg white. This protein is about two-thirds the size of serum albumin, and it contains sugar residues in addition to amino acid residues (that is, it is a glycoprotein). See Protein
