They put a smaller structure inside it called a heme, a large flat molecule that is the active part of hemoglobin.
This anti-inflammatory signaling agent upregulates the expression of a gene that encodes for a cell-protective substance called heme oxygenase 1 HO-1.
The sphere in the center of the heme is an iron atom.
Red meat in general also has high levels of a type of iron called heme that, when consumed in high amounts, can increase oxidative stress and lead to chronic inflammation, which can also affect insulin production.
During sepsis, red blood cells can become injured and leak an iron-based substance called heme that's normally part of the hemoglobin that carries oxygen.
Meat-derived iron, known as heme iron, is more easily absorbed by the body.
One substance that has to cross the cell membrane is a molecule called heme, which plays a crucial role in supplying the cell with the energy needed to carry out the chemical reactions that sustain life.
(one of the components that makes heme, which is needed to make hemoglobin).
Nrf2 is a transcription factor that is essential for the antioxidant response element (ARE) - mediated induction of genes such as heme-oxygenase 1 (HO-1).
This effect is especially helpful when you eat the less-easily-absorbed “nonheme” iron, found in nonanimal sources, such as tofu, spinach, raisins and fortified cereal meat, fish and poultry deliver heme iron, which your body absorbs more easily.
