<p>CSV import</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Methyl group&#039;&#039;&#039; is an [[alkyl]] derived from [[methane]], containing one [[carbon]] atom bonded to three [[hydrogen]] atoms — CH&lt;sub&gt;3&lt;/sub&gt;. The methyl group is commonly found in many [[organic compound]]s, including [[biological system]]s.<br /> <br /> == Structure and properties ==<br /> The methyl group is a type of [[alkyl]] group, derived from [[methane]]. It consists of a [[carbon]] atom bonded to three [[hydrogen]] atoms. The formula for a methyl group is CH&lt;sub&gt;3&lt;/sub&gt;. <br /> <br /> In terms of its structure, the methyl group is [[tetrahedral]]. This is due to the carbon atom forming four bonds in a tetrahedral geometry. <br /> <br /> The properties of the methyl group can vary depending on the rest of the molecule. However, it is generally non-polar and hydrophobic. <br /> <br /> == Biological importance ==<br /> Methyl groups are important in [[biology]], where they are involved in [[methylation]] reactions. Methylation is a form of [[alkylation]] with a methyl group, and its role in biological processes includes [[DNA methylation]] and [[protein methylation]]. <br /> <br /> DNA methylation, for example, is a crucial part of [[cell differentiation]] and is a common marker in [[DNA replication]] and [[DNA repair]] pathways. <br /> <br /> == Chemical reactions ==<br /> Methyl groups can participate in a variety of chemical reactions, including [[substitution reaction|substitution reactions]], [[addition reaction|addition reactions]], and [[elimination reaction|elimination reactions]]. <br /> <br /> In substitution reactions, a methyl group can replace a hydrogen atom or other substituent. In addition reactions, a methyl group can add to a double bond or triple bond. In elimination reactions, a methyl group can be removed from a molecule, often with the formation of a double bond or triple bond.<br /> <br /> == See also ==<br /> * [[Methylation]]<br /> * [[Methyltransferase]]<br /> * [[Methyl donor]]<br /> * [[Methyl accepting chemotaxis protein]]<br /> <br /> [[Category:Functional groups]]<br /> [[Category:Alkyl groups]]<br /> [[Category:Organic compounds]]<br /> <br /> {{stub}}</div>
