Haemoglobin a1c

(Science: haematology) The substance of red blood cells that carries oxygen to the cells and sometimes joins with glucose.

Because the glucose stays attached for the life of the cell (about 4 months), a test to measure haemoglobin a1c shows what the persons average blood glucose level was for that period of time.

Re: oxygen "grabbers" haemoglobin adaptation?

To a Chemical Engineer like me (retired) the term "oxygen grabber" can mean chemicals like hemoglobin, or wet iron used to remove atmospheric oxygen in lab work, or even the presence of such materials in the workplace which may pose an industrial hazard (like the inside of a rusting steel...

Re: carbon dioxide and haemoglobin

Carbon dioxide combines reversibly with haemoglobin to form carbaminohaemoglobin. Carbon dioxide does not bind to iron, as oxygen does, but to amino groups on the polypeptide chains of haemoglobin. Thanks a lot. John Messick
