THE BIOSYNTHESIS OF RICINOLEIC ACID

1. Ricinoleic acid is shown to be synthesized in the immature castor bean seed only after 3-4 weeks from the time of fertilization. 2. Synthesis occurs both in the isolated embryo and the endosperm. 3. Linoleic acid does not act as precursor of ricinoleic acid in the isolated bean embryo. 4. Oleic a...

Description
Summary:1. Ricinoleic acid is shown to be synthesized in the immature castor bean seed only after 3-4 weeks from the time of fertilization. 2. Synthesis occurs both in the isolated embryo and the endosperm. 3. Linoleic acid does not act as precursor of ricinoleic acid in the isolated bean embryo. 4. Oleic acid is shown to be the direct precursor of ricinoleic acid. 5. The reaction does not use molecular oxygen. This suggests that ricinoleic acid is not a precursor of linoleic acid.
