Lipids and Lipoprotein Complex in Photosynthetic Tissues

Abstract

Anacystis nidulans cells were fractionated, and characterized. The Hill reaction activity of the lamellar fractions depended at a considerable degree on the media used in cell fractionations and on the freshness of the cells. Analytical results suggest that two types of lamellae are present in the cells. One existing in the cell in a large amount, showed higher content of chlorophyll and lower carotenoids. The other which seems to be located near cell membrane, had carotenoids in relatively higher concentration, and contained probably a chlorophyll absorbing far-red light in addition to a common chlorophyll a.
