1-Octadecyl-sn-glycero-3-phosphocholine is an intermediate in the ether lipid metabolism pathway. 1-Octadecyl-sn-glycero-3-phosphocholine is irreversibly produced from 2-acetyl-1-(9Z-octadecenyl)-sn-glycero-3-phosphocholine via the enzyme 1-alkyl-2-acetylglycerophosphocholine esterase (EC 3.1.1.47). 1-Octadecyl-sn-glycero-3-phosphocholine is an ether phospho-ether lipid. Ether lipids are lipids in which one or more of the carbon atoms on glycerol are bonded to an alkyl chain via an ether linkage, as opposed to the usual ester linkage. Plasmalogens are glycerol ether phospholipids. They are of two types, alkyl ether (-O-CH2-) and alkenyl ether (-O-CH=CH-). Dihydroxyacetone phosphate (DHAP) serves as the glycerol precursor for the synthesis of plasmalogens. Three major classes of plasmalogens have been identified: choline, ethanolamine and serine derivatives. Ethanolamine plasmalogen is prevalent in myelin. Choline plasmalogen is abundant in cardiac tissue. Usually, the highest proportion of the plasmalogen form is in the ethanolamine class with rather less in choline, and commonly little or none in other phospholipids such as phosphatidylinositol. In choline plasmalogens of most tissues, a higher proportion is often of the O-alkyl rather than the O-alkenyl form, but the reverse tends to be true in heart lipids. In animal tissues, the alkyl and alkenyl moieties in both non-polar and phospholipids tend to be rather simple in composition with 16:0, 18:0 and 18:1 (double bond in position 9) predominating. Ether analogues of triacylglycerols, i.e. 1-alkyldiacyl-sn-glycerols, are present at trace levels only if at all in most animal tissues, but they can be major components of some marine lipids. 1-Octadecyl-sn-glycero-3-phosphocholine is an intermediate in the ether lipid metabolism pathway. 1-Octadecyl-sn-glycero-3-phosphocholine is irreversibly produced from 2-acetyl-1-(9Z-octadecenyl)-sn-glycero-3-phosphocholine via the enzyme 1-alkyl-2-acetylglycerophosphocholine esterase (EC 3.1.1.47). 1-Octadecyl-sn-glycero-3-phosphocholine is an ether phospho-ether lipid.

(15Z)-tetracos-15-enoylcarnitine

(15Z)-tetracos-15-enoylcarnitine is an acylcarnitine. More specifically, it is an (15Z)-tetracos-15-enoic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. (15Z)-tetracos-15-enoylcarnitine is therefore classified as a very-long chain AC. As a very long-chain acylcarnitine (15Z)-tetracos-15-enoylcarnitine is generally formed in the cytoplasm from very long acyl groups synthesized by fatty acid synthases or obtained from the diet. Very-long-chain fatty acids are generally too long to be involved in mitochondrial beta-oxidation. As a result peroxisomes are the main organelle where very-long-chain fatty acids are metabolized and their acylcarnitines synthesized (PMID: 18793625). Altered levels of very long-chain acylcarnitines can serve as useful markers for inherited disorders of peroxisomal metabolism. The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].
