A pinch of poison is good for a body, at least if it's heme. In minuscule amounts, it works in cells as an essential catalyst called a cofactor and as a signaling molecule to trigger other processes.

Heme, a crucial component of the biomachinery that squeezes energy out of food and stores it for later use, must be transported across membranes but without exposing its central iron atom to oxidation ...

The S1 C-terminal domain of the spike protein of SARS-CoV-2 contains the receptor-binding domain (RBD), which is responsible for interaction with the angiotensin-converting enzyme 2 (ACE2) receptor ...

Researchers identified a significant link between heme iron—iron found in red meat and other animal products —and risk of type 2 diabetes (T2D), as well as the metabolic pathways underlying the link.

It is the latest of several major findings by University of Maryland Professor of Animal and Avian Sciences Iqbal Hamza and his group that fill in key pieces in the puzzle of how animals prioritize ...

It took an unlikely food innovation -- earth-friendly vegetarian patties, made to taste and "bleed" like the familiar meaty ones -- to make people aware of heme. But heme is an essential part of ...

Higher intake of heme iron, the type found in red meat and other animal products - as opposed to non-heme iron, found mostly in plant-based foods - was associated with a higher risk of developing type ...
