State of decay lifeline

chemical decomposition

Putrefaction involves fermentation. Putrefaction is important because elements such as nitrogen, phosphorus and sulfur that are bound to dead matter are converted into a usable form by plants.

The approximate time of the onset of decay depends on several factors. Internal factors affecting the rate of decay include the age at which death has occurred, the general structure and condition of the body, the cause of death, and external injuries that arise before or after death. External factors include ambient temperature, humidity and exposure to air, clothing, burial factors, and exposure to light.

Certain substances, such as carbolic acid, arsenic, strychnine and zinc chloride, can be used to retard the putrefaction process in various ways based on their chemical composition.

In thermodynamic terms, all organic tissues are composed of chemical energy, which, when not maintained by the constant biochemical maintenance of the living organism, begins to break down chemically due to reaction with water into amino acids, known as hydrolysis. The disintegration of proteins in a decomposing body is a spontaneous process. Protein hydrolysis is accelerated as anaerobic bacteria in the digestive tract consume, digest and excrete cellular proteins from the body.

time of decomposition of a body

To begin with, the process of decomposition of a human body, seen in the simplest way, what it does is to transform the macro-molecular biological components of who once had life, taking it initially to simpler molecules, to finally return it to the Lithosphere (Earth), where it came from.

Here comes the first point to consider and ask, if really the fetid cadaveric odors and that really are highly unpleasant, can cause us disease?… the answer is no, because these odors are generated from substances that are mostly the product of the decomposition of proteins, in amino acids, forming substances called as the eschatol and indole, putrescine and cadaverine, which will form the characteristic odors of the decomposed corpses.

It is necessary to keep in mind that these are odors that in spite of being unpleasant, do not produce disease, but from the opposite point of view if it is possible, that also as product of the decomposition of the organic matter (corpses of alive beings), really toxic compounds can be generated, such as hydrogen sulfide, which can cause death, but only in cases of decomposed corpses and accumulated in confined spaces such as caves, so you should always be cautious about entering deep closed sites without any ventilation, as it could be exposed to toxic gases of this type.

One can differentiate between abiotic and biotic decomposition (biodegradation). The first means “degradation of a substance by physical or chemical process”; e.g., hydrolysis. The latter means “the metabolic breakdown of materials into simple components by living organisms”.

Five main stages in the process of decomposition are described: fresh, swollen, actively putrefying, advanced putrefaction, and dry or debris.[1] The general stages of decomposition are paired with two phases of chemical decomposition: autolysis and putrefaction.[2] These two phases contribute to the process of chemical decomposition, which breaks down the major components of the body.

This stage begins immediately after the heart stops beating.[3] Since blood no longer circulates through the body, it accumulates in portions, under gravity, creating a total bluish discoloration called livor mortis. Just after death, within three to six hours, the muscle tissues become rigid and unable to relax, a stage known as rigor mortis. From the moment of death, the body begins to lose heat to the environment, producing a complete cooling called algor mortis.[4] The body then begins to lose heat to the environment.
