In acetone extracts the presence of chlorophyll a and b caused enhanced photodecomposition of monogalactosyl diglyceride. Irradiation of isolated etioplasts containing chlorophyllide and monogalactosyl diglyceride caused photodecomposition of chlorophyllide but not of monogalactosyl diglyceride. In irradiated etiochloroplasts containing chlorophyll a and monogalactosyl diglyceride both components were photodecomposed. During photodecomposition of monogalactosyl diglyceride the fatty acid composition remained constant.
