The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a ...
Examples of early transition metal catalysts includes titanium and zirconium complexes. Early transition metals can easily form oxides; therefore, protection groups, like the use of methylaluminoxane (MAO) due to its Lewis acidity , can be used to prevent side reactions from happening. [ 13 ]
In organic chemistry, functionality is often used as a synonym for functional group. For example, a hydroxyl group can also be called a HO-function. [1] [2] Functionalisation means the introduction of functional groups, for example the functionalisation of a surface [3] (e.g. silanization for the specific modification of the adhesion of a surface)

Polysaccharides (sugar polymers) can be linear or branched and are typically joined with glycosidic bonds. The exact placement of the linkage can vary, and the orientation of the linking functional groups is also important, resulting in α- and β-glycosidic bonds with numbering definitive of the linking carbons' location in the ring.
In general, biodegradable polymers can be grouped into two large groups based on their structure and synthesis. One of these groups is agro-polymers, or those derived from biomass. [1] The other consists of biopolyesters, which are those derived from microorganisms or synthetically made from either naturally or synthetic monomers.
End groups are seen on all polymers and the functionality of those end groups can be important in determining the application of polymers. Each type of polymerization (free radical, condensation or etc.) has end groups that are typical for the polymerization, and knowledge of these can help to identify the type of polymerization method used to form the polymer.
It also contains an ester functional group (in red), and an acetyl functional group (encircled with dark green). Other divisions can be made. In organic chemistry, a moiety (/ ˈ m ɔɪ ə t i / MOY-ə-tee) is a part of a molecule [1] [2] that is given a name because it is identified as a part of other molecules as well.
