Bilirubin

... fishy somewhere. I don’t quite get the connection between the stated concentration and the dilution. If you start off with a 2 mg/ml solution of bilirubin and dilute that 1:500, you expect 0.004 mg/ml of bilirubin (not 2 – 0.004 = 1.996 mg/ml). That converts to 6.848E-6 mole/L of bilirubin. The ...

The following calculation is from a lab at uni recently. I had to make a 1:500 dilution of chloroform in 2mg/ml bilirubin. This gives a bilirubin concentration of 1.996mg/ml. The molar extinction coefficient of bilirubin is 60700 and has a MW of 584. I tried to calculate percentage ...

... in vivo using noninvasive measurements of cutaneous spectral remittance (diffuse reflectance). Although the blood chromophores Hb, HbO2, and bilirubin determine dermal absorption of wavelengths longer than 320 nm, scattering by collagen fibers largely determines the depths to which these ...

Well...the bilirubin gives it a yelllow color. Bilirubin is the main bile product and it's caused by the breakdown of hemoglobin (via the liver) but bile is also made up of water, cholesterol, bile salts, electrolytes and phospholipids.
