C19-gibberellin 6-carboxylic acids are c19-gibberellins with a carboxyl group at the 6-position. Gibberellin a15 is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Gibberellin a15 can be found in a number of food items such as winter squash, common pea, common wheat, and chayote, which makes gibberellin a15 a potential biomarker for the consumption of these food products.
