Adenosine Triphosphate (ATP) and Metabolism

Chemistry
In discussing the chemistry of the human body, the media features many important substances. Take water. We are told how important it is to drink lots of water. Our body cells do consist, after all, of about 60% water. And we repeatedly hear of DNA, cholesterol, free radicals, omega fatty-acids, trans fat and sodium. Yet, there is one essential compound that is seldom mentioned... adenosine triphosphate, acronym ATP. Have you heard-tell of ATP? No? Yet it is remarkably important – you could not exist without it. Besides, even if you could, the energy you'd need to function would be totally unavailable. ATP - What Is It? ATP, on examination (see image) is one molecule consisting of three portions. There is an adenine portion attached to a ribose (sugar) portion, attached…

Rigor Mortis – Not a Lucky Stiff

Chemistry, Medicine
When a person or animal dies, it doesn’t take long before the body grows cold and stiff. Cold makes obvious sense, but why stiff? Why does rigor mortis [Latin for stiffness of death] set in? Chemistry of Rigor Mortis Rigor mortis results from chemical changes within the muscles - it’s body chemistry. The chemical enabling muscle flexing is ATP (adenosine triphosphate). When breathing ceases, breathing ceases. Lack of oxygen severely diminishes ATP production. If the individual dies, the body begins cooling right away, but muscle stiffening does not set in immediately.

It involves anaerobic glycolysis, the breakdown of glucose into lactic acid. Simply written, it is…
