what exactly are ester bonds?

Ester bonds are formed by the reaction of an acid and alcohol.
In biological molecules you find ester bonds in lipids where the carboxyl group of a fatty acid reacts with the hydroxyl group of triglycerol.
R-C=O + HO-R' -> R-C=O +H2O

The ester bond is the vertical line.
In biologically important molecules you also have the esters of phosphoric acid with alcohols, like in the backbone of DNA and RNA, in mononucleotides, phosporylated amino acids in post-translationaly modified proteins like phospho- serine, threonine, tyrosine.

an ester bond would be C-O-C where 2 carbons are attached by an oxygen you can see this in a glucose molecule
