Glyoxysomes are specialized organelles found in germinating seeds and fungi that allow the conversion of fatty acids into carbohydrates. Harry Beevers discovered glyoxysomes in 1961 through analyzing sucrose gradients of plant extracts and finding glyoxylate cycle enzymes in a distinct organelle, which he and Breidenbach named glyoxysomes. Glyoxysomes contain enzymes for breaking down fatty acids as well as the glyoxylate cycle enzymes isocitrate lyase and malate synthase, which allow the conversion of fatty acid derivatives into carbohydrates that the growing seedling can use.
