Thus, these experiments indicate that labile alkyl compounds can be a source of the insoluble aliphatic component of fossil organic matter in the absence of a resistant aliphatic precursor (e.g. cutan) in the living organism.作者: Monotonous 時間: 2025-3-22 05:56

The aliphatic component is primarily derived from incorporation of the original fatty acids into a solvent insoluble polymer, as demonstrated by performing similar experiments with model lipid compounds. Bacterial biomass can, therefore, contribute significantly to the insoluble organic inventory in ancient sediments.作者: BUMP 時間: 2025-3-22 16:29 作者: 詞匯記憶方法 時間: 2025-3-22 18:31 作者: ciliary-body 時間: 2025-3-22 22:48 作者: phytochemicals 時間: 2025-3-23 04:30

In the absence of cutan, other constituents—cutin, plant waxes and internal plant lipids—are incorporated into the geomacromolecule and contribute to the formation of a resistant fossil geopolymer.作者: flaggy 時間: 2025-3-23 11:01
