 Title    Arachidonic Acid in the Lipids of Marine Algae Maintained under Blue, White and Red Light  
 Abstract    Marine algae, maintained for one month under blue, white and red light were rather rich in lipids but obviously poor in fat (triacylglycerols). These lipids consisted predominantly of glyco-lipids and phospholipids. Irrespective of the light quality, the major constituent fatty acids in lipids of these algae were, in most cases, those with 20 carbon atoms. The light quality had a definite effect on the proportion of arachidonic acid in the lipids of certain algae. Thus, the proportion of arachidonic acid in Enteromorpha intestinalis maintained under white light was 45% and in Sargassum salicifolium kept under red light 25% of the total constituent fatty acids in the total algal lipids.

 Title    Die Strukturen der essentiellen ungesättigten Fettsäuren, Kristallstruktur der Linolsäure sowie Hinweise auf die Kristallstrukturen der a-Linolensäure und der Arachidonsäure The Structures of the Essential Unsaturated Fatty Acids. Crystal Structure of Linoleic Acid and Evidence for the Crystal Structures of a-Linolenic Acid and Arachidonic Acid  
 Abstract    The essential fatty acids linoleic, a-linolenic and arachidonic acid have been crystallized for the first time. The crystal and molecular structures have been elucidated by X-ray analysis. Linoleic acid crystallizes monoclinic P2ijc with a = 4298(3), b — 463.2(3), c = 937.7(6) pm, ß = 109.38(8)°, Z = 4. The closely packed molecules are stretched with a ttttttsCssCstt conformation a . By comparison of the unit-cell constants and calculated densities of the unsaturated fatty acids it may be shown that both a-linolenic acid and arachidonic acid also possess stretched structures in the crystal lattice, a-linolenic acid must display a ttttttsCssCssCs and arachidonic acid a ttsCssCssCssCsttt conformation.
