SYNOPSIS. Anuran bile pigments when concentrated in the large intestine at elevated pH levels, may diffuse into the cytoplasm of opalinids, there be reduced to stercobilin and crystallized. Stercobilin crystals persisted unchanged in Zelleriella cultured in vitro for 14 days.

Bile pigment-phospholipid interactions
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1971Abstract The binding of conjugated and free bilirubin with various phospholipids to form aggregates, which were not extracted by alkali, was examined under various conditions and in different solvents. Maximum binding was attained with lecithins, unsaturated cephalin, and sphingomyelin while lysolecithin and cardiolipin formed negligible amounts of ...

Bile acids, bile pigments and colorectal cancer risk
Current Opinion in Gastroenterology, 2022Purpose of review The gut microbial co-metabolism of bile-derived compounds (e.g. bile acids and bile pigments) affects colorectal cancer (CRC) risk. Here, we review recent findings with focus on selected novel aspects of bile-associated effects with interesting but unclear implications on CRC risk.

Bile Pigment Formation in Plants
Science, 1970The unicellular alga Cyanidium caldarium evolves carbon monoxide during the synthesis of the bile pigment, phycocyanobilin. Carbon monoxide and phycocyanobilin were produced in stoichiometric amounts at comparable rates. Therefore, the mechanism of bile pigment formation in this plant parallels that in mammals.

Biliverdin pigments in green biles
Biochimica et Biophysica Acta (BBA) - General Subjects, 1965Abstract 1. 1. The nature of the green bile pigments in various animal species has been studied using reversed-phase partition chromatography and paper chromatography. 2. 2. The chromatographic behaviour of the pigments has been compared with that of synthetic biliverdin derivatives. 3. 3.

Bile Pigment Excretion in Amphibia
Nature, 1961IN man and in other mammals, bilirubin is excreted in conjugated form, mainly as the glucuronide. Since in mammalian fœtal liver the enzymatic mechanism for glucuronide formation is poorly developed, reaching its full capacity only after birth, transient hyperbilirubinaemia is frequently observed during the neonatal period1.

SUMMARY Plasma bile pigments were examined in experimental obstruction of one or both bile ducts (right cystic and left hepato-enteric ducts) in the chicken. A significant elevation in both unconjugated and conjugated bilirubin occurred only when both extra-hepatic bile ducts were ligated. Plasma bilirubin concentrations following obstruction of both
