PERMETHYLATION Meaning and
Definition
-
Permethylations, also referred to as methylation, can be defined as a chemical process where one or more methyl groups (CH3) are added to a molecule. The addition of these methyl groups is achieved by a reaction that involves replacing a hydrogen atom (H) on the molecule with a methyl group. This chemical modification plays a crucial role in various biological and chemical processes.
In the field of biology, permethylation is often associated with the modification of DNA and RNA molecules. Specifically, it refers to the addition of methyl groups to the nucleotide bases cytosine and adenine in DNA and uracil in RNA. This process, known as DNA or RNA methylation, can have significant effects on gene expression and regulation. Methylation patterns in DNA are essential for various biological processes, including embryonic development, cellular differentiation, and X-chromosome inactivation.
In addition to its role in nucleic acids, permethylation can also occur in other organic molecules, such as proteins and small molecules. The addition of methyl groups to proteins can affect their structure, function, and stability. In small organic molecules, methylation can alter their physicochemical properties, such as solubility, reactivity, and biological activity.
Permethylations are often catalyzed by enzymes called methyltransferases, which carry out the transfer of the methyl group from a donor molecule, such as S-adenosylmethionine (SAM), to the target molecule. These enzymatic reactions are tightly regulated and play critical roles in various biological processes, including epigenetics, metabolism, and signal transduction pathways.

Etymology of PERMETHYLATION
The term "permethylation" is derived from a combination of two words: "per" and "methylation".
1. "Per-" is a prefix that means "through", "thoroughly", or "completely". It is often used to intensify or extend the meaning of the word it precedes. In the context of "permethylation", it suggests a thorough or complete process of methylation.
2. "Methylation" refers to the addition of a methyl group (-CH3) to a molecule or a particular chemical compound. This process involves the transfer of a methyl group to a specific atom or functional group, resulting in the modification of the target compound.
Therefore, "permethylation" implies a process of complete or extensive methylation, where multiple methyl groups are added to a molecule.
