Here's what I get.

The general formula for an amino acid is usually written as #"H"_2"NCHRCOOH"# or #"RCH(NH"_2")COOH"#.

However, amino acids usually exist as zwitterions, an ionic form in which there are separate positively and negatively charged parts.

#"H"_3stackrelcolor(blue)("+")("N")"CHRCO"stackrelcolor(blue)("-")("O")#

The structural formula for the ionic form of serine is
