Fatty acids of acyl steryl glycoside (acyl SG) of different plants producing both green and photosynthetically inactive tissue have been analyzed. The major components are in all cases 16:0, 18:2 and 18:3 acids. The fatty acid composition of acyl SG of green parts is very similar to that of etiolated, pale or storage tissue of the same plant. Generally the degree of saturation of acyl SG is higher than that of the corresponding total lipid. Acyl SG tends to be more saturated in green parts than in colorless tissues of the same plant. Conversely, total lipid of green tissue containing large amounts of galactolipids and 18:3 acid is much less saturated than that of photosynthetically inactive tissue. Though containing smaller amounts of 18:3, and in some cases unsaturated C(16) acids, acyl SG does not reflect the drastic increase of these acids in the total lipid of green tissue. It is concluded that fatty acids of acyl SG originate mainly from an acyl donor other than chloroplast galactolipids.
