There is no chlorophyll pigment or chloroplast. They cannot perform photosynthesis and are heterotrophic or saprophytic. The cell structure forms mycelium which is composed of the hyphae which spread and help in attachment to the substratum.In the compound both ketone and the carboxylic group is present. Priority is given to carboxylic group at C-1, and the ketonic group at C-3 is treated as a substituent. Thus the prefix used is "keto" and the suffix used is "oic acid".
