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.
Oxygen transport. The human body needs iron for oxygen transport. Oxygen (O2) is required for the functioning and survival of nearly all cell types (mature erythrocytes being one exception). Oxygen is transported from the lungs to the rest of the body bound to the heme group of hemoglobin in erythrocytes. In muscles cells, iron binds myoglobin, which regulates its release.
