# Tagging functional group

Is it a standard practice to name functional group by the greek alphabet of the carbon it is attached to?

Recently read a question in which the order of translation (protein synthesis) was asked and there were a couple of options with the $\ce{NH2}$ was labelled as $\ce{\alpha-NH2}$ and $\ce{COOH}$ as $\ce{\alpha-COOH}$.

I read wiki, it says H atoms are labeled in that way but are functional groups too labeled in the same way?

• As you can see, they are. – Mithoron Apr 29 '17 at 15:50
• Definitely not standard though. Standard is nothing but the IUPAC name. These are simply useful notations chemists use in certain chemicals as they have useful properties being that way. – Pritt Balagopal Apr 29 '17 at 16:39
