Heme iron is found in the diet mainly in the form of hemoglobin and myoglobin. The mechanism of iron absorption remains uncertain. This study focused on the heme iron uptake by Caco-2 cells from a hemoglobin digest and its response to different iron concentrations. We studied the intracellular...
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...
bronchiseptica must acquire iron (Fe) from the infected host. A vast amount of Fe within the host is sequestered within heme, a metalloporphyrin which is coordinately bound in hemoglobin and myoglobin. Utilization of hemoglobin and myoglobin as sources of nutrient Fe by B. bronchiseptica requires ...
The meaning of HEME is the deep red iron-containing prosthetic group C34H32N4O4Fe of hemoglobin and myoglobin.
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...

The term heme defines an organic compound containing an iron atom between the structure of the porphyrin ring. Porphyrin is an organic compound that has a ring-like structure. The heme attached with the hemoglobin molecule or myoglobin is known as the heme group, while the separate heme is ...
Oxidative stress derived from the iron accumulated in the amyloid plaques originating from amyloid β (Aβ) peptides and neurofibrillary tangles derived from hyperphosphorylated tau proteins has been implicated in the pathogenesis of Alzheimer's disease (AD). Altered heme homeostasis leading to ...
