alpha carbon
This term is a specialized technical designation used almost exclusively in organic chemistry and biochemistry. It identifies a specific spatial relationship within a molecule, serving as a reference point for numbering carbon chains relative to a functional group, such as a carboxyl or carbonyl group.
Because it refers to a specific structural position, the term is used in a descriptive, scientific register. It is typically paired with terms like reactivity, substitution, or chirality when discussing the chemical properties of amino acids or other organic compounds.
Meanings
Examples
The alpha carbon is the central point of an amino acid.
Look at the diagram to see how the side chain attaches to the alpha carbon.
I wonder if the substitution occurs at the alpha carbon or the beta carbon.
In most amino acids, the alpha carbon is a chiral center.
The bond between the alpha carbon and the carboxyl group is quite stable.
Wait, does the hydrogen atom attach directly to the alpha carbon?
The geometry around the alpha carbon is tetrahedral.
The researcher analyzed the chemical shift of the alpha carbon using NMR.
