Albumin was used to test its effect on the in vitro bactericidal activity of cefditoren against penicillin-resistant Streptococcus pneumonia. It has been clinically used in serious and often life-threatening conditions, such as shock and blood loss due to trauma, burns, and surgery. It was used also to test the effect of non-enzymatic glycation on the unfolding of human serum albumin.

Biochem/physiol Actions

Serum albumin functions as a carrier protein for steroids, fatty acids, and thyroid hormones, and is vital in regulating the colloidal osmotic pressures of blood. Albumin is also seen to bind to exogenous substances, particularly drugs (e.g., ibuprofen, warfarin), and strongly influence their pharmacokinetics. Oxidative stress leading to changes in the redox state of albumin has widely varied effects on its physiological function.

General description

Albumin is the most copious protein in blood plasma. Liver produces human albumin.

Lipid Induced Insulin Resistance

Obesity is a well-established risk factor for the development of insulin resistance. Obesity is associated with the increased deposition of lipids in non-adipose tissue with subsequent decreases in i...
