Moiety (chemistry)
In organic chemistry, a moiety (/ˈmɔɪəti/) is a part of a molecule[1][2] which is typically given a name as it can be found within other kinds of molecules as well. For instance, the acetyl moiety is a component of many organic compounds, including acetic acid, acetylcholine, acetyl-CoA, acetylcysteine, acetaminophen (also known as paracetamol), and acetylsalicylic acid (better known as aspirin).
Larger moieties are often functional groups,[3] which are made up of atoms that participate in similar chemical reactions in most molecules that contain them.[4] Moieties and functional groups may contain smaller moieties, or be contained in a larger moiety. For example, methyl p-hydroxybenzoate contains a phenol functional group within the acyl moiety, which in turn is part of the paraben moiety. Larger moieties are often functional groups.[3]
Moieties that constitute branches extending from the backbone of a hydrocarbon molecule, which can often be broken off and substituted with others, are called substituents or side chains.
