What is the systematic name for the functional group in esters?

[Mattara]

The (main) functional group in esters are:

R_1OOR_2

Where R_1 and R_2 are carbon chain.

When I though about it, I've never heard the systematic name of this functional group. What is this functional group called? I've seen esterbonding etc. but that doesn't sound systematic as ex. alkoxy group, carbonyl group and so on.

This isn't a homework or course question...

The functional group in an ester is
RCOOR'

The esters are named alkyl alkanoates. Since esters can be produced by the reaction between alcohols and carboxylic acids, the alkyl part comes from the corresponding alcohol and the alkanoate comes from the corresponding acid.
