Abstract/OtherAbstract:
|
The fatty acids of the major glycerolipids of Vicia faba leaves were analyzed immediately following (14)CO(2) feeding. The leaves were fractionated into chloroplast and cytoplasmic fractions and the location of radioactivity in the fatty acids determined. The results indicate that the major site of incorporation of fatty acids is in the phospholipids. Phosphatidylcholine contained the highest level of radioactivity in the cytoplasmic fraction, whereas phosphatidylglycerol contained radioactivity in both the chloroplast and cytoplasmic fractions. The galactolipids contained very little radioactivity in comparison, this radioactivity being confined to high speed centrifugal fractions believed to contain the envelopes of the chloroplast. Our results suggest that phosphatidylcholine is a major site of incorporation of fatty acids (mainly in oleic acid) in the cytoplasm, whereas phosphatidylglycerol is also a site of incorporation involving both oleic and palmitic acids, inside and outside the chloroplast. |
