Bilirubin (BR) (from the Latin for "red bile") is a red-orange compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates.This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged or abnormal red blood cells. [3]
Bilirubin, a yellow bilin, is a breakdown product of heme Bilins , bilanes or bile pigments are biological pigments formed in many organisms as a metabolic product of certain porphyrins . Bilin (also called bilichrome) was named as a bile pigment of mammals , but can also be found in lower vertebrates , invertebrates , as well as red algae ...
In the human liver, bile is composed of 97–98% water, 0.7% bile salts, 0.2% bilirubin, 0.51% fats (cholesterol, fatty acids, and lecithin), and 200 meq/L inorganic salts. [ 2 ] [ 3 ] The two main pigments of bile are bilirubin , which is orange-yellow, and its oxidised form biliverdin , which is green.
They are composed primarily of bilirubin (insoluble bilirubin pigment polymer) and calcium (calcium phosphate) salts that are found in bile. They contain less than 20% of cholesterol (or 30%, according to the Japanese classification system). [38] Between 2% and 30% of stones are bilirubin stones. [3]
(Bilirubin's conformation is also affected by light, a fact used for the phototherapy of jaundiced newborns.) [7] Phycobilins are also closely related to the chromophores of the light-detecting plant pigment phytochrome, [8] which also consist of an open chain of four pyrroles.
7. Soy Can Affect Fertility in Men. Soy has come a long way. Once dismissed as “hippie food,” today it’s a popular protein alternative for vegetarians and vegans.
The porphyrin moieties in our red blood cells, whose primary function is to bind iron atoms which capture oxygen, result in the heme chromophores which give human blood its red color. Heme is degraded by the body into biliverdin (which gives bruises their blue-green color), which in turn is degraded into bilirubin (which gives patients with ...
All biological pigments selectively absorb certain wavelengths of light while reflecting others. [4] [5] The principal pigments responsible are: Chlorophyll is the primary pigment in plants; it is a chlorin that absorbs blue and red wavelengths of light while reflecting a majority of green. It is the presence and relative abundance of ...
