Longchainmethyl branched 1-methoxyalkanes, a new class of ether lipids, have been identified from silk of the spider Linyphia triangularis (Araneae: Linyphiidae) by use of gas chromatographic retention indices, GC/MS investigations, and chemical modifications. Methyl groups are predominantly located at C-2, and ω-3 or ω-2 positions, respectively. Chain length varies between C24 and C32. The synthesis
