Failure in the regulation of glyceroneogenesis may lead to type 2 diabetes, a metabolic disorder that results in high levels of blood glucose and blood lipid. [5] Type 2 diabetes, in addition to a decreased sensitivity to insulin , is associated with the overproduction of triglycerides in the liver, due to excessively active glyceroneogenesis ...
The structure of cytochrome b5 reductase, the enzyme that converts methemoglobin to hemoglobin. [1]Methemoglobin (British: methaemoglobin, shortened MetHb) (pronounced "met-hemoglobin") is a hemoglobin in the form of metalloprotein, in which the iron in the heme group is in the Fe 3+ state, not the Fe 2+ of normal hemoglobin.

In chemistry, a precursor is a compound that participates in a chemical reaction that produces another compound. In biochemistry , the term "precursor" often refers more specifically to a chemical compound preceding another in a metabolic pathway , such as a protein precursor .
Gluconeogenesis (GNG) is a metabolic pathway that results in the biosynthesis of glucose from certain non-carbohydrate carbon substrates. It is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms. [1]
The average red blood cell contains 250 million hemoglobin molecules. [7] Hemoglobin contains a globin protein unit with four prosthetic heme groups (hence the name heme-o-globin); each heme is capable of reversibly binding with one gaseous molecule (oxygen, carbon monoxide, cyanide, etc.), [8] therefore a typical red blood cell may carry up to one billion gas molecules.
Reduction in the average blood lead level is believed to have been a major cause for falling violent crime rates in the United States. [125] A statistically significant correlation has been found between the usage rate of leaded gasoline and violent crime: the violent crime curve virtually tracks the lead exposure curve with a 22-year time lag.
The first attempts to manufacture fuel gas in a commercial way were made in the period 1795–1805 in France by Philippe LeBon, and in England by William Murdoch. Although precursors can be found, it was these two engineers who elaborated the technology with commercial applications in mind.
