Ver. long chain-satur.ted and-polyunsatur.ted fatty acids(VLC-SFA and VLC-PUFA, r.spectively) ar. a functionally impor.ant class of fatty acids containing 28 car.ons or.mor. in their.acyl chain. They ar. synthesized by the elongation of ver. long fatty acids-4(ELOVL4) enzyme, expr.ssed mainly in the br.in, r.tina, skin, testes, and meibomian gland, wher. these fatty acids ar. found(Agbaga et al., 2008). Fur.her. these or.ans exhibit tissuespecific VLC-PUFA and VLC-SFA biosynthesis and incor.or.tion into complex lipids for.specific functions. In the br.in, skin, and Meibomian glands, the ELOVL4 mainly makes VLC-SFA, which ar. incor.or.ted into complex sphingolipids. In the r.tina, the ELOVL4 makes VLC-PUFA that ar. incor.or.ted into phosphatidylcholine, that ar. cr.tical for.visual function, while in testes and sper., the VLC-PUFA ar. incor.or.ted into sphingolipids that ar. cr.tical for.fer.ility(Yeboah et al., 2021).

The influence of soaking time in deep cr.ogenic tr.atment on the tensile and impact pr.per.ies of low-alloy medium-car.on HY-TUF steel was investigated in this study. Micr.str.ctur.l studies based on phase distr.bution mapping by electr.n backscatter.diffr.ction show that the deep cr.ogenic pr.cess causes a decr.ase in the content of r.tained austenite and an incr.ase in the volume fr.ction of η-car.ide with incr.asing soaking time up to 48 h. The decr.ase in the content of r.tained austenite fr.m ~1.23vol% to 0.48vol% suggests an isother.al mar.ensitic tr.nsfor.ation at 77 K. The η-type pr.cipitates for.ed in deep cr.ogenic-tr.ated mar.ensite over.48 h have the Hir.tsu and Nagakur. or.entation r.lation with the mar.ensitic matr.x. Fur.her.or., a high coher.ncy between η-car.ide and the mar.ensitic matr.x is obser.ed by high-r.solution tr.nsmission electr.n micr.scopy. The var.ations in macr.har.ness, yield str.ngth, ultimate tensile str.ngth, and ductility with soaking time in the deep cr.ogenic pr.cess show a peak/plateau tr.nd.
