#heme — Public Fediverse posts

The potential link btwn red #meat consumption & #cancer may be partially mediated by the high intake of #heme iron. Vegetarian & #vegan diets often surpass the #iron intake of omnivorous #diets. Well-planned #plantbased diets can be nutritionally adequate: doi.org/10.1007/s136... #nutrition #health

old but interesting research article [2017]:

Extracellular glycine is necessary for optimal hemoglobinization of erythroid cells
https://pmc.ncbi.nlm.nih.gov/articles/PMC5541866/

"Vertebrate heme synthesis requires three substrates: succinyl-CoA, which regenerates in the tricarboxylic acid cycle, iron and glycine. For each heme molecule synthesized, one atom of iron and eight molecules of glycine are needed."

@itsveganjim Years ago the WHO listed #meat as #carcinogenic.

Note the bit about #heme iron for those claiming that they must eat meat to treat #anaemia. Get an iron infusion. I promise that, in the long run, that's a more cost-effective treatment for the #healthcare system and #ecosystem.

Hi @DNPFred
In grad school I worked on heme proteins using #paramagnetic #NMR and #NRVS. Then I shifted to #XRayCrystallography, using #EPR #UVVis and #EDX on #crystals when a postdoc. My research group works on #NonHemeIron #enzymes, & #heme, #copper & #manganese #metalloproteins. Really interested in combining #spectroscopy on #protein #crystals to examine #structure #function relationships.
