Background Heme iron is found in the diet mainly in the form of hemoglobin and myoglobin. It is known that heme iron (heme-Fe) and inorganic iron are absorbed differently. Intracellularly, heme oxygenase-1 (HO1) participates in the cleavage of the heme ring producing biliverdin, CO and fer...
The P450 (CYP) superfamily of enzymes is found in virtually all organisms where they catalyze the oxidation of endogenous and exogenous organic compounds. These reactions are vital steps in the biosynthesis of steroids and other hormones, and the detoxification and oxidative removal of xenobiotics. ...
Heme iron found in muscle protein should be supplied to humans to prevent iron deficiency, which can lead to anemia. It is easily absorbed and its main source is red meat. In addition, heme iron, which is mainly found in myoglobin in meat, contributes to the desirable bright red color ...
Heme iron, one of two types of iron found in foods, is bound to either the blood protein hemoglobin or the muscle protein myoglobin. 血红素铁一般结合在血液中的血红蛋白或肌肉中的肌红蛋白中,是食品中发现的铁元素存在的两种形式中的一种。 news.dxy.cn 3. The chief differences between chlorophyll...

Our results suggest that intake of dietary heme iron is associated with an increased risk of proximal colon cancer, especially among women who drink, but that intake of dietary zinc is associated with a decreased risk of both proximal and distal colon cancer. 展开 ...

The iron responsive regulator Irr is found in a wide range of -proteobacteria, where it regulates many genes in response to the essential but toxic metal iron. Unlike Fur, the transcriptional regulator that is used for iron homeostasis by almost all other bacterial lineages, Irr does not sense...
Besides pointing out the ease of synthesis of porphyrins it is of interest to note that porphyrins are very stable molecules for they are found in fossilized excrements of crocodile and mineral hydrocarbon oils contain porphyrins presumably of both plant and animal origin. 展开 关键词:...
