Fatty Acids in Chloroplasts and Leaves

Lipid metabolism in the rumen: New insights on lipolysis and biohydrogenation with an emphasis on the role of endogenous plant factors

“…However leaf lipid FA are mainly based on GL, with a low energy content and a 25% higher PUFA content than TAG, which is connected to GL's metabolic and structural roles in photosynthesis (Dörman and Benning, 2002). The higher levels of PUFA in plant leaves are mainly due to LNA, which is positively correlated with total lipid content (Crombie, 1958) and rate of photosynthesis Allakhverdiev et al (2001), whose results confirm those of previous studies showing that water soluble carbohydrates tend to increase during daylight (Orr et al, 1997). Photosynthesis takes place in the thylakoid membrane which is a fluid mosaic containing proteins, lipids and pigments (Heinz and Siefermann-Harms, 1981).…”

“…Variations in the lipid composition of fresh forages are due to many factors, including plant species (Crombie, 1958;Shorland, 1961;Roughan and Batt, 1969;Melo et al, 1995;Addis et al, 2005;Cabiddu et al, 2005) cultivars within species Adapted and calculated from Roughan and Boardman (1972). tr = trace.…”

Chlorophyll Synthesis in Chlorella I. Occurrence of a Lag Phase on Initiation of a Dilute Culture

“…Crombie and Bloch and his group have suggested the involvement of oa-linolenic acid in photosynthetic 02 evolution (5,7,10,11). Benson has suggested that a-linolenate is the major fatty acid associated with chloroplast galactolipid (3,4).…”
