Ketosis is a nutritional process characterised by serum concentrations of ketone bodies over 0.5 mM, with low and stable levels of insulin and blood glucose. It is almost always generalized with hyperketonemia, that is, an elevated level of ketone bodies in the blood throughout the body.
Hemoglobin (American) or haemoglobin (British) (/ËhiËmÉËÉ¡loÊbÉªn, ËhÉ-, -moÊ-/[1][2][3]); abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of all vertebrates[4] (with the exception of the fish family Channichthyidae[5]) as well as the tissues of some invertebrates.
Iron is mainly absorbed in the duodenum and upper jejunum. A transporter protein called divalent metal transporter 1 (DMT1) facilitates transfer of iron across the intestinal epithelial cells. DMT1 also facilitates uptake of other trace metals, both good (manganese, copper, cobalt, zinc) and bad (cadmium, lead).nly a small fraction of the body's iron is gained or lost each day. Most of the iron in the body is recycled when old red blood cells are taken out of circulation and destroyed, with their iron scavenged by macrophages in the mononuclear phagocyte system, mainly spleen, and returned to the storage pool for re-use.
