Bile

As part of my healing process, I've thrown up for years.

Often, green, thick and bitter. I think that's conjugate of bile salts or whatever the correct term is.

There's something else orange, "clear liquid" and sour. Another bile thing I believe, but not conjugate.

I have a form of Cystic Fibrosis and we misprocess salts and fats. This may not be relevant to anyone else.

I have no idea.

But if you are going through something similar, that's what I think I'm throwing up: Stuff involved in making bile, I guess. (I have a shockingly poor understanding of bile and the gallbladder. My interest developed as a consequence of experiencing what I understand to be routinely puking up bile or bike components.)

Conjugate bile refers to bilirubin that has been processed by the liver, made water-soluble, and prepared for excretion into the bile.
Bilirubin is a yellow pigment produced from the breakdown of old red blood cells. Initially, it exists as unconjugated bilirubin, which is fat-soluble and toxic if accumulated, and it travels in the bloodstream bound to albumin. In the liver, this bilirubin undergoes conjugation, a chemical process where the enzyme UGT1A1 attaches glucuronic acid molecules to bilirubin, converting it into conjugated bilirubin. This form is water-soluble, allowing it to mix with bile and be excreted into the intestines for elimination from the body

Conjugated bile is a major component of bile and is essential for the digestion and absorption of fats. Its water-soluble nature also enables it to be filtered by the kidneys, which is why elevated levels in the blood, known as conjugated hyperbilirubinemia, can indicate liver dysfunction, bile duct obstruction, or other hepatobiliary disorders

Key points about conjugated bile:

Formed in the liver from unconjugated bilirubin via glucuronidation.
Water-soluble, unlike unconjugated bilirubin.
Excreted into bile and eventually eliminated through the intestines.
Elevated blood levels may signal liver disease, bile duct obstruction, or genetic transport defects like Dubin-Johnson syndrome

Understanding conjugated bile is important in clinical diagnostics, as measuring direct (conjugated) bilirubin helps distinguish between liver processing issues and excessive red blood cell breakdown, guiding appropriate medical evaluation and treatment

That seems likely as a partial explanation. When it's not orange or whatever.
