metálico

Metílico refers to anything containing or derived from a methyl group. A methyl group is a functional group in organic chemistry with the chemical formula CH3. It consists of one carbon atom covalently bonded to three hydrogen atoms. The term "metílico" is a Spanish adjective, translating to "methyl" in English, and is used in scientific contexts to describe chemical compounds or properties related to this specific chemical structure.

In chemistry, the methyl group is a fundamental building block. It can be found attached to a larger molecule, forming a methyl substituent, or as part of a larger functional group, such as a methyl ester or methyl ether. For example, methanol is an alcohol with the formula CH3OH, where the methyl group is bonded to a hydroxyl group. Methane, the simplest alkane, consists solely of a carbon atom bonded to four hydrogen atoms, and can be considered the parent hydrocarbon from which the methyl group is derived by removing one hydrogen atom.

The presence of a methyl group can significantly influence the physical and chemical properties of a molecule. It is a relatively small, nonpolar group, contributing to properties like solubility and reactivity. In biological systems, methylation, the addition of a methyl group to a molecule, is a crucial biochemical process that plays a role in gene regulation, metabolism, and signal transduction. Therefore, "metílico" signifies a connection to this fundamental chemical entity.
