Mass spectrometry method introduces novel concept for in-cell protein characterization

Proteins in cells are highly flexible and often exist in multiple conformations, each with unique abilities to bind ligands. These conformations are regulated by the organism to control protein function. Currently, most studies on protein structure and activity are conducted using purified proteins in vitro, which cannot fully replicate the complexity of the intracellular environment and may be influenced by the purification process or buffer conditions.

Consumer Reports found that several brands of ground cinnamon contain #lead . It begs the question of: what about other ground spices? Many places around the world don't follow good food safety standards. They're not tested at the border when imported. A great project for someone with the equipment would be to test various spices from various places. Maybe other common contaminants too. It would be a great study. Let me know if you do -- happy to write about it.
And, what about spices in #Canada? Many come from the same sources.
ADDENDUM: Another thought. Maybe some of those long-term, large population studies could test for lead, etc. in some of the blood samples they collect. Could be a good indicator.

The 12 Cinnamon Powders You Should Never Use

Twelve of the 36 cinnamon powders and spice blends containing cinnamon had high levels of lead, according to Consumer Reports' testing.
