Boletocrocin

General structure. If R = OH (aspartic acid), boletocrocin A; R = NH2 (asparagine), boletocrocin B.

Boletocrocin is any one of a group of seven closely related organic compounds, individually named boletocrocin A through boletrocrocin G.[1] These compounds are polyene dicarboxylic acids that include both lipophilic and polar amino acids.[2] They were extracted from the brightly colored mushrooms Boletus laetissimus and B. rufoaureus.[2] The boletocrocins' conjugated systems account for the intense color.

Related biological pigments are present in other fungi, such as calostomal (from Calostoma cinnabarinum),[3] melanocrocin (from Melanogaster broomeianus),[4] and mycenaaruin A (from Mycena aurantiomarginata).[1]
