THE fourth Pedler Lecture of the Chemical Society was delivered by Prof. Hans Fischer at the Royal Institution on February 22, his subject being the constitution of chlorophyll A. Prof. Fischer has been working on blood and leaf pigments in Munich for a number of years, and has recently ...
the study area were analyzed according to the FVCOM model. In winter, the sea surface temperature in the south of the study area was significantly higher than that in the north, and the temperature difference between the north and south was obvious. In summer, the distribution of sea surface ...

Chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis. Chloroplasts are a type of plastid that are distinguished by their green color, the result of specialized chlorophyll pigments. In plants, chloroplasts
Chlorophyll is a green pigment found in all plants. This green pigment is not only responsible for giving plants their green color, but also aids...

Photosystem II is a multi-subunit supramolecular machinery composed of proteins, numerous pigments (chlorophylls (Chls) and carotenoids), and other cofactors. It comprises two main moieties; the core complex for charge separation, and the peripheral antenna system for light capture and energy transfer...
Peroxisomes and glyoxysomes, often referred to under the general heading of “microbodies”, represent analogous cell organelles which compartmentalize the H2O2-producing sections of metabolic pathways. Microbodies are eukaryotic and thus are not...
Chlorophylls a and b, beta-carotene, alpha-tocopherol, tyrosol and their interactions effects on Tunisian extra virgin olive oil (EVOO) were studied. Beta-carotene, used at a level of 7 ppm, has an antioxidant effect more important at li... I Ben Tekaya,M Hassouna - 《Oléagineux Corps...
Chlorophyll b is found in photosynthetic prokaryotes and primary and secondary endosymbionts, although their light-harvesting systems are quite different. Chlorophyll b is synthesized from chlorophyll a by chlorophyllide a oxygenase (CAO), which is a Rieske-mononuclear iron oxygenase. Comparison of the ...
