F‐Säure‐haltige Phospholipidmoleküle in Zuckerrohrzellen

Abstract

F Acid‐Containing Phospholipids in Sugar Cane Cells Heterotrophic suspension cultures of sugar cane (Saccharum spec.) cells contain the F acids 1b–f. These acids are bound preferably to phosphatidylethanolamine 3 and phosphatidylcholine 4. Structures of F acid‐containing phospholipid molecular species 3b–d, 4b and 4c were established by enzymatic positional hydrolysis and GC/MS analysis of the respective (trimethylsilyl)diacylglycerol derivatives 5.

Furan fatty acids: Occurrence, synthesis, and reactions. Are furan fatty acids responsible for the cardioprotective effects of a fish diet?

“…F-acids were also found in marine bacteria (43)(44)(45), algae (46,47), plants (48)(49)(50), yeast (49) and fungi (49), food fats such as butter (51) and virgin olive oil (52), mammalian tissue (53), and blood in-cluding that of humans (54)(55)(56). Thus, F-acids seem to be widely distributed in all living matter.…”

“…To remove radiation-induced radicals, plants and algae are assumed to generate F-acids and incorporate them into PC (50). Thus, for instance, antioxidant activity in soybean PC liposomes is recognized (128).…”

Three New Furan Derivatives and a New Fatty Acid from a Taiwanese Marine Sponge Plakortis simplex

“…Furan fatty acids are commonly isolated from fish lipids, − but also from a number of marine organisms such as diatoms, crayfish, , ascidians, scallops, soft corals, and sponges. , Reports of their isolation from plant sources are less common. − The furan fatty acid (8 Z ,11 Z ,14 Z ,17 Z )-3,6-epoxyeicos-3,5,8,11,14,17-hexenoic acid isolated from the New Zealand sponge Hymeniacidon huraki 12 was responsible for the cytotoxicity of its extract (P-388; IC 50 13.4 μg/mL), whereas the methyl and stearyl esters of the acid showed inflammatory activity.…”

“…11,12 Reports of their isolation from plant sources are less common. [13][14][15][16] The furan fatty acid (8Z,11Z,14Z,17Z)-3,6-epoxyeicos-3,5,8,11,14,17-hexenoic acid isolated from the New Zealand sponge Hymeniacidon huraki 12 was responsible for the cytotoxicity of its extract (P-388; IC 50 13.4 µg/mL), whereas the methyl and stearyl esters of the acid showed inflammatory activity.…”

Isolation of the Furan Fatty Acid, (8Z,11Z,14Z,17Z)-3,6-Epoxyeicos-3,5,8,11,14,17-hexenoic Acid from the New Zealand Sponge Hymeniacidon hauraki

“…

Furan fatty acids have been previously found in a number of marine organisms including crayfish (1,2), diatoms(3), soft corals (4), ascidians (5), and scallops (5), but have been isolated most commonly from fish lipids (5-10). Reports of their isolation from plant sources are less common (11)(12)(13)(14). We now report the isolation of the furan fatty acid, (8Z,llZ,l4Z,17Z)-3,6-epoxyeicos-3,5,8,11,14,17-hexenoic acid [1] from the New Zealand marine sponge, Hymeniacidon hauraki (family Hymeniacidonidae, order Halichondrida).
