Biliverdin (from the Latin for green bile) is a green tetrapyrrolic bile pigment, and is a product of heme catabolism. [1][2] It is the pigment responsible for a greenish color sometimes seen in bruises. [2] Biliverdin results from the breakdown of the …

2022年12月8日 · Bilirubin and biliverdin are two yellow pigments produced during the breakdown of red blood cells. Bilirubin is the main pigment in bile, while biliverdin is a green pigment that is converted to bilirubin. Bilirubin and biliverdin are both important for the excretion of waste products from the body. What is Bilirubin? What is Biliverdin?

2023年5月1日 · Biliverdin is a tetrapyrrolic, water-soluble compound formed by the breakdown of heme.[1] Heme is broken down into biliverdin and carbon monoxide and iron by heme oxidase. Biliverdin is then quickly broken down to bilirubin by biliverdin reductase.[2]

Biliverdin(2-) is dicarboxylate anion of biliverdin; major species at pH 7.3. It has a role as a human metabolite. It is a linear tetrapyrrole anion and a dicarboxylic acid dianion. It is a conjugate base of a biliverdin.

Bilirubin is a waste product produced by the breakdown of heme, a component of hemoglobin, when macrophages either in spleen or liver remove senescent erythrocytes. Heme consists of a Fe 2 + ion in the center of porphyrin.

Biliverdin is one of the three by-products of heme oxygenase (HO) activity, the others being ferrous iron and carbon monoxide. Under physiological conditions, once formed in the cell, BV is reduced to bilirubin (BR) by the biliverdin reductase (BVR).

2023年5月1日 · Biliverdin is a tetrapyrrolic, water-soluble compound formed by the breakdown of heme. Heme is broken down into biliverdin and carbon monoxide and iron by heme oxidase. Biliverdin is then quickly broken down to bilirubin by biliverdin reductase.

2024年1月1日 · Heme catabolism produces biliverdin, a green tetrapyrrolic bile pigment known by its Latin name, green bile. It is the pigment that gives bruises their occasionally greenish hue. Heme oxidase converts heme to biliverdin, iron, and carbon monoxide.

2023年10月1日 · Biliverdin is a by-product of heme oxygenase and the substrate of biliverdin reductase. If the reductase is inhibited, biliverdin accumulates and green jaundice occurs. Biliverdin has shown in vitro beneficial roles in free radical-related diseases.
