title: Methyl trisporate E. A sex pheromone in Phycomyces blakesleeanus.
abstract: Combined mating type cultures of Phycomyces blakesleeanus accumulate 41 mg of trisporic acids/l of medium, of which 30% is trisporic acid E. The methyl ester of trisporic acid E exhibits the same zygophore -inducing activity in bioassays with P. blakesleeanus and Mucor mucedo as does the pheromone methyl trisporate C. The structure of methyl trisporate E is 1,5-dimethyl-2-hydroxyl-4-oxo-6-(2'-hydroxyl-6'- methylocta -5',7'-d ien-8'-yl) -5-cyclohexene-1-carboxylic acid methyl ester.
