Creation and history
Friedrich August Kekulé von Stradonitz
The need for an international standard for chemistry was first
addressed in 1860 by a committee headed by German scientist Friedrich
August Kekulé von Stradonitz. This committee was the first
international conference to create an international naming system for
organic compounds. The ideas that were formulated in that
conference evolved into the official
IUPAC nomenclature of organic
chemistry. IUPAC stands as a legacy of this meeting,
making it one of the most important historical international
collaborations of chemistry societies. Since this time,
IUPAC has been the official organization held with the responsibility
of updating and maintaining official organic nomenclature.
IUPAC as such was established in 1919. One notable country
excluded from this early IUPAC is Germany. Germany's exclusion was a
result of prejudice towards Germans by the Allied powers after World
Committees and governance
IUPAC is governed by several committees that all have different
responsibilities. The committees are as follows: Bureau, CHEMRAWN
(Chem Research Applied to
All committees have an allotted budget to which they must adhere. Any committee may start a project. If a project's spending becomes too much for a committee to continue funding, it must take the issue to the Project Committee. The project committee either increases the budget or decides on an external funding plan. The Bureau and Executive Committee oversee operations of the other committees.

Nomenclature Main article: Preferred IUPAC name IUPAC committee has a long history of officially naming organic and inorganic compounds. IUPAC nomenclature is developed so that any compound can be named under one set of standardized rules to avoid duplicate names. The first publication on IUPAC nomenclature of organic compounds was A Guide to IUPAC Nomenclature of Organic Compounds in 1900, which contained information from the International Congress of Applied Chemistry.
Organic nomenclature IUPAC organic nomenclature has three basic parts: the substituents, carbon chain length and chemical ending. The substituents are any functional groups attached to the main carbon chain. The main carbon chain is the longest possible continuous chain. The chemical ending denotes what type of molecule it is. For example, the ending ane denotes a single bonded carbon chain, as in "hexane" (C6H14). Another example of IUPAC organic nomenclature is cyclohexanol:
Cyclohexanol The substituent name for a ring compound is cyclo. The indication (substituent name) for a six carbon chain is hex. The chemical ending for a single bonded carbon chain is ane The chemical ending for an alcohol is ol The two chemical endings are combined for an ending of anol indicating a single bonded carbon chain with an alcohol attached to it. Inorganic nomenclature Basic IUPAC inorganic nomenclature has two main parts: the cation and the anion. The cation is the name for the positively charged ion and the anion is the name for the negatively charged ion. An example of IUPAC nomenclature of inorganic chemistry is potassium chlorate (KClO3):
Nucleic acid code
A or G
C, T or U
G, T or U
Bases which are ketones
A or C
Bases with amino groups

Not A (i.e. C, G, T or U)
B comes after A
Not C (i.e. A, G, T or U)
D comes after C

H comes after G
Neither T nor U (i.e. A, C or G)
V comes after U

The codes for amino acids (24 amino acids and three special codes) are:

This book identifies that there are many different techniques and theories about minerals, microorganisms, and organic components individually, but they are not often associated with each other. It further goes on to discuss how these components of soil work together to affect terrestrial life. Interactions Between Soil Particles and Microorganisms: Impact on the Terrestrial Ecosystem gives techniques to analyze minerals, microorganisms, and organic components together. This book also has a large section positing why environmental scientists working in the specific fields of minerals, microorganisms, and organic components of soil should work together and how they should do so.
