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.
Red blood cells contain the oxygen-carrier protein hemoglobin. It is composed of four globular peptides, each containing a heme complex. In the center of each heme, lies iron (Figure 10.6). Iron is a key component of hundreds of metabolic enzymes.Many of the proteins of the electron-transport chain contain ironâsulfur clusters involved in the transfer of high-energy electrons and ultimately ATP synthesis.ron is a key component of hundreds of metabolic enzymes.
