Abstract
The sulphoquinovosyldiacylglycerol (sulpholipid) zone obtained by TLC of pe a chloroplast lipids yields, on hydrolysis, not only sulphoquinovose but al so galactose and glucose. Following incorporation from UDP-[C-14]glucose, t he percentages of the total radioactivity in these three sugars were typica lly 1, 5 and 85%, respectively. The occurrence of the glucolipid causes dif ficulties in elucidating further the biosynthetic pathway for sulphoquinovo se.
