“…9-desaturase is a central enzyme to synthesize the long chain monounsaturated fatty acids (LCMUFAs) from long chain saturated fatty acids (LCSFAs), which catalyze stearic acid (SA, 18:0) and palmitic acid (PA; C16:0) to oleic acid (OA, 18:1 9 ) and palmitoleic acid (POA, C16:1 9 ) (Figure 1). Scientists also have identified and characterized the various 9-fatty acid desaturase gene from Rhodotorula toruloides (20) and Pseudomonas sp.…”

“…Some desaturase can convert ω-6 fatty acids to ω-3 fatty acids, which is named ω-3 desaturase. 15-desaturase is a kind of ω3-desaturase with C18 fatty acid as substrate, which catalyzes linoleic acid (LA, 18:2 9,12 ) and γ-linolenic acid (GLA, C18:3 6,9,12 ) to α-linolenic acid (ALA, C18:3 9,12,15 ) and stearidonic acid (SDA, C18:4 6,9,12,15 ), respectively. Scientists found that low temperature and high salinity could motivate the upregulation of CiFAD3 (coding 15-desaturase) expression in Chlamydomonas reinhardtii (71).…”

“…Adapt to a lowtemperature marine environment, deep-sea fish oil is rich in LCPUFAs, enriched from the marine microalgae (7,8). Some plants such as soybeans, flax, and peanut, can store lipid in their seed, from which humans could extract and harvest linoleic acid (LA, 18:2 9,12 , ω6) and α-linolenic acid (ALA, C18:3 9,12,15 , ω3) rich oil (9,10). However, harvesting the LCPUFAs from plants and deep-sea fish is a timeconsuming process, which was also limited by climate, land and ecological environment (11,12).…”

Dietary bioactive lipids, one of the three primary nutrients, is not only essential for growth and provides nutrients and energy for life's activities but can also help to guard against disease, such as Alzheimer's and cardiovascular diseases, which further strengthen the immune system and maintain many body functions. Many microorganisms, such as yeast, algae, and marine fungi, have been widely developed for dietary bioactive lipids production. These biosynthetic processes were not limited by the climate and ground, which are also responsible for superiority of shorter periods and high conversion rate. However, the production process was also exposed to the challenges of low stability, concentration, and productivity, which was derived from the limited knowledge about the critical enzyme in the metabolic pathway. Fortunately, the development of enzymatic research methods provides powerful tools to understand the catalytic process, including site-specific mutagenesis, protein dynamic simulation, and metabolic engineering technology. Thus, we review the characteristics of critical desaturase and elongase involved in the fatty acids' synthesis metabolic pathway, which aims to not only provide extensive data for enzyme rational design and modification but also provides a more profound and comprehensive understanding of the dietary bioactive lipids' synthetic process.

Rich in unsaturated fatty acids, walnut oil provides a number of physiological benefits, including a reduction in the risk of cardiovascular disease and a delay in the aging process. In this work, walnut oil was prepared using the aqueous enzyme process and cold pressing method, and it was then analyzed using HPLC and FTIR. The characterization results show that the walnut oil extracted by the aqueous enzyme method outperformed the pressing oil in content of LLL by 11.64%, LLLn by 9.16% and OLL by 4.08%. But this oil had significantly less OLnLn (‐) than the pressing oil (7.90%). The Morris water maze and shuttle box tests of ICR mice revealed a notable improvement in the memory of the animals administered walnut oil. Among them, mice fed the walnut oil extracted by aqueous enzyme method showed a much shorter escape latency and a significantly higher rate of active avoidance reaction (p < 0.05, p < 0.01) than mice fed cold pressing method. With the prolongation of time, the mice even performed better than the positive control PIR group in all aspects. In summary, the quality of walnut oil extracted by aqueous enzyme method is better than that by cold pressing method.Practical Applications: Walnut oil prepared by aqueous enzymatic extraction can improve learning ability, is healthy and pollution‐free, and can be utilized as a dietary supplement in ordinary life.
