General description
Linoleic acid is an essential and highly consumed polyunsaturated fatty acid (PUFA). Albumin is a globular protein. Bovine serum albumin (BSA) is composed of a single polypeptide chain and cross-linked cysteine disulfide bridges. BSA is heart-shaped and is made up of three homologous domains I-III and each domain has two subdomains A and B.
Application
Linoleic Acid-Albumin from bovine serum albumin has been used: in cell culture and to study its effects on the human colonic adenocarcinoma cell line. It has also been used in the in vitro culture (IVC) of cow embryos/zygotes. The binding of linoleic acid to BSA improves its stability and solubility in culture media.
Biochem/physiol Actions
Linoleic acid plays a role in maintaining the transdermal water barrier in epidermis. Serum albumin constitutes about 52-62% of the total water-soluble fraction proteins in the blood plasma.
