Question

b) Estrogen
c) vitamin D
d) Bilirubin​

Answer 1

Bile salts are synthesized in the liver from cholesterol, conjugated with glycine or taurine and secreted in bile with cholesterol and lecithin.

Explanation:

Unused cholesterol remains in more cholesterol-rich chylomicron remnants, and taken up from here to the bloodstream by the liver. VLDL molecules are produced by the liver from triacylglycerol and cholesterol which was not used in the synthesis of bile acids.
