Fat Metabolism in Higher Plants: LVII. A Comparison of Fatty Acid-Synthesizing Enzymes in Chloroplasts Isolated from Mature and Immature Leaves of Spinach.

Chloroplasts isolated from immature leaves of spinach (Spinacia oleracea) differ in enzyme levels from those isolated from mature leaves. On a chlorophyll basis, immature chloroplast preparations had 5- to 6-fold higher capacity to synthesize fatty acids from 2-(14)C-acetate compared to plastids isolated from mature leaves. This difference was correlated… CONTINUE READING
