"Methuselah" Natural Recordings by Native Speakers
Methuselah is a biblical figure who is renowned for being the oldest person to have ever lived, according to the Book of Genesis. He is said to have lived to the age of 969 years. The term "Methuselah" has come to be used metaphorically to refer to someone or something that is extremely old or ancient. In some contexts, it can also suggest a life cut short or an unusual longevity.
Methoxsalen is a synthetic compound that is primarily used as a topical cream or ointment to treat various skin conditions, including vitiligo, psoriasis, and eczema. It is also used to induce repigmentation in cases of vitiligo.
Methoxy is a chemical suffix used to describe a type of functional group in organic chemistry. It is a prefix that indicates the presence of a methyl ether functional group, which is a molecule with a carbon-oxygen bond.<br><br>In simpler terms, methoxy refers to a group of atoms that includes a carbon atom, a bond with an oxygen atom, and a methyl group (a type of hydrocarbon). This group is often found in molecules such as ethers, esters, and polycyclic aromatic hydrocarbons.
A methoxyl group is a functional group in organic chemistry that consists of a methyl group (-CH3) bonded to an oxygen atom (-O-). It is a common substituent in many organic compounds, particularly in biochemistry and pharmacology.
Methoxyphenamine is a synthetic derivative of amphetamine, a central nervous system stimulant. It was previously used as an appetite suppressant and a Peripheral vascular dilator, but its use has been largely discontinued due to concerns over its potential for addiction and other negative side effects.
Meths is a shortened form of "methanol", which is a type of liquid fuel used in engines, stoves, and other equipment.
Methscopolamin is a medication that belongs to the group of anticholinergics. It is used to relax muscles and reduce secretion of saliva, sweat, and tears. It is commonly used before anesthesia or surgery to reduce secretions and help improve respiratory and oral intubation.
Methuen is a proper noun, specifically the name of a town in Massachusetts, United States. It can also refer to the Dukes of Methuen, a title of nobility in the United Kingdom.
Methyl refers to a chemical group composed of one carbon atom and three hydrogen atoms, denoted as -CH3. It is a functional group found in many organic compounds, including hydrocarbons, alcohols, and amines.
Methylal is a chemical compound with the formula CH3OHCH3. It is a colorless, volatile liquid with a sweet, pungent odor. Methylal is a precursor to acetone and is used as a solvent, a fuel additive, and in the production of certain chemicals.
Methylamine is a chemical compound with the formula CH3NH2. It is a colorless gas with a strong, ammonia-like odor. Methylamine is a primary amine, meaning it has a single amine group (-NH2) bonded to a hydrocarbon chain. It is a precursor to many pharmaceuticals, dyes, and pesticides, and is also used in the production of plastics and other materials.
Methylase is a type of enzyme that adds a methyl group (CH3) to a molecule, typically to modify or regulate its function. Methylases are involved in various biological processes, including DNA methylation, protein modification, and metabolism.
To methylate is a chemical process where a methyl group (-CH3) is added to a molecule. Methylating agents can add a methyl group to another molecule, such as a protein or a nucleotide, changing its structure, function, or activity. This process is important in various biological processes, including the regulation of gene expression, protein function, and signal transduction. In general, methylating agents play a crucial role in maintaining the balance of cellular physiology.
Meaning: Methylated refers to a compound that contains a methyl group, which is an alkyl substituent derived from methane. In chemistry, methylated compounds are those that have a methyl (-CH3) functional group attached to another molecule.
