“…Phosphatidylcholine (PC) (e.g., C42, C44, C46) and diglyceride (DAG) (e.g., C31, C35, C37, C39, C41, C43, C47) lipids accounted for 39.4% and 26.0% of the lipids in GOF, respectively, whereas DAGs (e.g., C33, C35, C37, C39, C41, C43, C47) showed a higher classification proportion (53.9%) in LFF (Figure 2). Our data also revealed that the majority of DAGs in both LFF and GOF contained highly polyunsaturated fatty acids (e.g., 30:4, 32:3, 34:5, 40:9, 44:12), which could be more susceptible to microbial degradation in the soil than saturated fatty acid molecules [24]. Conversely, PC lipids containing N and P identified in GOF may degrade and release essential elements rather slowly due to its long-chain structure and the relatively high degree of fatty acid saturation.…”
