Abstract

Intact spinach and barley chloroplast normally incorporate 14C-acetate into palmitate and oleate as the major 14C fatty acids. Addition of nitrite markedly altered the relative patterns of the products with the appearance of stearate, a drop in oleate, but no marked change in palmitate. Arsenite greatly increased appearance of palmitate with a concomitant decrease in the C18 fatty acids. The effect of other anions was also examined. Spinach and barley plants grown under different nitrogen nutritional conditions also served as sources of chloroplasts, and their activities suggest a correlation between nitrite reductase activity and stearate accumulation.
