L-Alaninol acts as the sole carbon source for Pseudomonas sp. strain KIE171, and it is a metabolite produced by the hydrolysis of γ-glutamyl-L-alaninol. L-Alaninol functions as a substrate for oxidative/deaminative degradation and undergoes enzymatic glutamylation via IpuC. It is used as a synthetic building block in the fields of agriculture, pharmaceuticals, and peptide chemistry, and also serves as a chiral auxiliary.

(Rac)-sn-Glycerol 3-phosphate is an a-site substrate analogue. (Rac)-sn-Glycerol 3-phosphate is bound to the a-site, the rate of reaction of indole and nucleophilic indole analogues with E(A-A) is strongly inhibited.

18:0,18:1 PS sodium is the dominant phosphatidylserine subtype in cells, exosomes and HIV particles. It is abundant in the brain and is essential for maintaining membrane structure, lipid raft organization and intracellular trafficking. 18:0,18:1 PS sodium mediates interleaflet membrane coupling through cholesterol-dependent interactions with very long-chain sphingolipids, and can induce the clustering of glycosylphosphatidylinositol-anchored proteins. In addition, clusters formed by the binding of 18:0,18:1 PS sodium to cholesterol not only facilitate the proper distribution of cholesterol in lipid bilayers, but also effectively protect cholesterol from oxidative damage.

1-Stearoyl-2-arachidonoyl-sn-glycero-3-phosphocholine is a major phospholipid in low-density lipoprotein and belongs to the group of 1-acyl phosphatidylcholines. 1-Stearoyl-2-arachidonoyl-sn-glycero-3-phosphocholine does not induce morphological changes in washed human platelets. 1-Stearoyl-2-arachidonoyl-sn-glycero-3-phosphocholine can be used for the research of atherosclerosis and thrombotic diseases.

Ethyl palmitate (Ethyl hexadecanoate) is a CHIKV virus inhibitor with an EC₅₀ value of 0.0068 μM. Ethyl palmitate can reduce levels of TNF-α, IL-6, and NF-κB in endotoxemic rats, showing anti-inflammatory activity.

1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine (SLPC; 18:0-18:2 PC) is an endogenous phospholipid marker molecule in the glycerophospholipid metabolic pathway. 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine is a core component of the phospholipid bilayer of biological membranes and a key responsive lipid for radiation injury and cardiometabolic diseases. 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine constitutes the phospholipid bilayers of cell membranes and high-density lipoprotein (HDL), and regulates the core activity of lipoprotein functional homeostasis. The content of 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine in mouse serum shows a significant dose-dependent decrease with increasing ionizing radiation dose, and its level in human HDL also decreases significantly in metabolic syndrome. 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine can serve as a biological dosimeter marker for ionizing radiation injury, and is used for rapid and accurate assessment of radiation absorbed dose in exposed individuals. 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine can also act as a lipidomics research target for cardiometabolic diseases such as lipid metabolic syndrome and early-onset coronary heart disease.

1,3-Dipalmitin (1,3-Dipalmitoylglycerol) is a diacylglycerol compound that can be found in the tuberous roots of Typhonium giganteum Engl. 1,3-Dipalmitin acts as an adsorption inhibitor for 1,3-diglycerides and β-carotene.

ER-Laurdan is a derivative of the membrane-permeable fluorescent probe Laurdan (HY-D0080) that targets the endoplasmic reticulum (ER). As a membrane fluidity reporter, ER-Laurdan specifically localizes to the ER luminal membrane, and exhibits a prominent solvatochromic response to fluidity changes caused by membrane packing and exogenous saturated fatty acid stress. ER-Laurdan shows no overlapping localization with mitochondria, enables quantitative analysis of ER membrane fluidity via generalized polarization ratio measurement, and allows automatic signal masking with the help of ER markers. With high specificity and quantitative capability, ER-Laurdan serves as an important tool for investigating metabolic disorders and associated changes in the physical properties of cell membranes.

Trierucin (Trierucoylglycerol) is a triester formed by glycerol and erucic acid, which serves as an occlusive skin conditioning agent and non-aqueous thickener in cosmetics. Long-term feeding of Trierucin to rats induces chronic toxicities such as cardiac lipid deposition and fibrosis.

Trimyristin is an orally active compound. Trimyristin can be isolated from the seeds of nutmeg (Myristica fragrans). Trimyristin inhibits the activities of acetylcholinesterase (AChE), ACP and ALP, with IC₅₀ values of 0.11, 0.16 and 0.18 mM, respectively. Trimyristin exerts competitive-noncompetitive inhibition on acetylcholinesterase, uncompetitive inhibition on ACP, and competitive/noncompetitive inhibition on ALP. Trimyristin restores the downregulated acetylcholinesterase concentration in the cerebral cortex of rats exposed to sodium arsenite. Trimyristin can be used in studies related to fascioliasis and neurotoxicity.
