Bacteriopheophytin APheophytin is a chlorophyll derivative involved in photosynthesis.
Chemical Formula:
C55H76N4O6
Layman's explanation:
Pheophytin is essentially a chlorophyll molecule with two hydrogen atoms
replacing the magnesium center. It can be synthesized through the
acidification of chlorophyll, where the magnesium is pulled from the porphyrin
ring and H+ ions attach to the open binding sites. The structure of pheophytin
is much more stable than that of the chlorophyll due to this hydrogen ion
interaction. As a result, pheophytin is a problem in laboratory situations
because the chlorophyll will spontaneously transform into pheophytin in any
acidic environment. The function of pheophytin is to carry excited electrons
from photosystem II and dump them off at the plastoquinone Qa during
photosynthesis. The pheophytin/chlorophyll interactions provide a source for a
wide range of research in the areas of botany, biology, and plant physiology.
The chemical structure is C55H72N4O6.
