Functional Groups

A functional team is a details group of atoms within a molecule the is responsible because that a properties of that molecule. Numerous invernessgangshow.netlogically energetic molecules save one or much more functional groups. In Bis2a us will discuss the major functional groups found in invernessgangshow.netlogical molecules. This include: Hydroxyl, Methyl, Carboxyl, Carbonyl, Amino and also Phosphate.

Hydroxyl R-OH

A hydroxyl (alcohol group) is one –OH group covalently bonded to a carbon atom. The oxygen atom is much an ext electronegative 보다 either the hydrogen or the carbon, i beg your pardon will cause the electrons in the covalent bonds to spend an ext time roughly the oxygen than around the C or H. Therefore, the O-H and O-C bond in the hydroxyl group will be polar covalent bonds. The figure listed below depict the partial dues δ+ and δ- linked with hydroxyl group.


The hydroxyl sensible group presented here consists of one oxygen atom bound to a carbon atom and a hydrogen atom. This bonds are polar covalent, an interpretation the electron involved in creating the bonds room not mutual equally in between the C-O and also O-H bonds. Attribution: developed Marc T.

The hydroxyl functional teams can type hydrogen bonds, presented as a dotted line. The hydrogen bond will kind between the δ- of the oxygen atom and a δ+ of the hydrogen atom. Dipoles presented in blue arrows. Attribution: Marc T. Facciotti (original work)

Hydroxyl teams are very common in invernessgangshow.netlogical molecules. Hydroxyl groups show up on carbohydrates (A), ~ above the R-groups of part amino acids (B), and also on nucleic acids (C). Have the right to you find any type of hydroxyl groups in the phospholipid in (D)?

The amine functional group can exist in a deprotonated or protonated state.

Once protonated the nitrogen atom is bound to 3 hydrogen atoms and has a confident charge. The deprotonated form of this group is neutral.Attribution: developed Erin Easlon (Own work)
