DEFINITION

Classification: 530/363

Serum albumin, e.g., BSA, HSA etc.:

(under subclass 363) Proteins having the structure of serum albumin and compounds derived from these by addition to or deletion of parts of the polypeptide structure.

(1) Note. Physical Properties: Molecular Weight: about 69.000 structure consists of carbohydrate-free polypeptide chain connecting four globular segments of unequal size stabilized by seventeen S-S bridges.

(2) Note. Physiological properties. Involved in osmotic regulation and the transport of sparingly soluble metabolic products from one tissue to another, especially in the transport of free fatty acids.

(3) Note. Synonyms. Albumin, from blood; Albuminate; Albuminar; Albumisol; Albuspan; Buminate; Pro-Bumin; Proserum.

(4) Note. CA Registry Number: 9048-46-8* [figure]
