C20-gibberellin 20-carboxylic acids are c20-gibberellins with a carboxyl group at the 20-position. Gibberellin a28 is slightly soluble (in water) and a weakly acidic compound (based on its pKa). Gibberellin a28 can be found in japanese pumpkin, scarlet bean, and winter squash, which makes gibberellin a28 a potential biomarker for the consumption of these food products.
