Heme is a coordination complex consisting of a porphyrin ring surrounding a single ferrous (Fe 2+) or ferric (Fe 3+) ion, able to bond with diatomic oxygen and transport it around the body. Four heme ...

Scientists have long been puzzled by how maturing red blood cells manage to produce all the hemoglobin they need to carry oxygen to tissues, even after shedding the vital structures they need to ...

Maturing precursor red blood cells display Heme Responsive Gene 1(HRG1) transporters (in green). These protein complexes are expressed on cell membranes and shuttle the iron-containing molecule heme ...

A new study from North Carolina State University identifies vertebrate hemoglobin in bone extracts from two dinosaurs and shows that this molecule is original to those animals. The work also shows how ...

Have you ever been told during a health checkup or blood test, “Your hemoglobin is low”? Sometimes you might be told, “You ...

Scientists have long been puzzled by how maturing red blood cells manage to produce all the hemoglobin they need to carry oxygen to tissues, even after shedding the vital structures they need to ...

A translational proteomics study identifies cerebrospinal fluid hemopexin as a candidate biomarker for secondary sepsis after ...

Many individuals consume generous portions of green vegetables and iron-dense foods yet find their clinical blood counts and hemoglobin readings stubbornly low. Clinical nutritionists point out that ...

Heme, a bioactive form of iron, has numerous essential functions in the cell. As a key component of hemoglobin, it enables oxygen transport in the blood. In addition, it performs important functions ...
