Bile pigment-phospholipid interactions

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1971
Abstract 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, 2022
Purpose 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, 1970
The 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, 1965
Abstract 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, 1961
IN 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.

Bile Pigments in the Chicken

Research in Veterinary Science, 1967
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

Bile Pigments from Normal Erythrocytes

Nature, 1949
Gardikas, Kench and Wilkinson1 have found that treatment of human erythrocytes with acetic acid in an oxygen-free atmosphere, in the absence of ascorbic acid, did not yield any biliverdin when the ether solution was extracted with 5 per cent hydrochloric acid.

Antioxidant Activities of Bile Pigments

Antioxidants & Redox Signaling, 2004
Biliverdin and bilirubin are reducing species and hence potential antioxidants formed by the action of heme oxygenase and biliverdin reductase. Indeed, there is increasing evidence for the suggestion that a beneficial role of the potentially toxic bilirubin may be to act as a powerful chain-breaking antioxidant in biological systems, and that bilirubin
