DHAP(18:0)

1-Octadecanoyl Dihydroxyacetone phosphate;1-stearoylglycerone 3-phosphate

C21H41O7P (436.25897660000004)

DHAP(18:0) is the octadecanoyl derivative of Dihydroxyacetone phosphate. It is also known as an alkyl-DHAP. This compound is formed by octadecanoic acid reacting with DHAP. Alkyl-DHAPs are intermediates in the synthesis of ether phospholipids. The initial steps of ether phospholipid biosynthesis take place in peroxisomes. Alkyl-dihydroxyacetonephosphate synthase is the peroxisomal enzyme that actually introduces the ether linkage. Levels of Alkyl-DHAP have been found to be strongly reduced in human fibroblasts derived from Zellweger syndrome and rhizomelic chondrodysplasia punctata patients. Four other enzymes are known to be involved in the metabolism of acyl-DHAP and alkyl-DHAP. These include: acyl-DHAP/alkyl-DHAP oxidoreductase, DHAP acyltransferase, alkyl-DHAP phosphohydrolase, and a dinitrofluorobenzene-insensitive acyl-DHAP acylhydrolase. Dihydroxyacetone phosphate (DHAP) is a biochemical compound primarily involved in the glycolysis metabolic pathway. DHAP is also the product of the dehydrogenation of L-glycerol-3-phosphate which is part of the entry of glycerol (sourced from triglycerides) into the glycolytic pathway. Conversely, reduction of glycolysis-derived DHAP to L-glycerol-3-phosphate provides adipose cells with the activated glycerol backbone they require to synthesize new triglycerides. Both reactions are catalyzed by the enzyme glycerol 3-phosphate dehydrogenase with NAD+/NADH as cofactor. DHAP may be referred to as glycerone phosphate in older texts. 1-Octadecyl-glycerone-3-phosphate is an intermediate in Ether lipid metabolism. DHAP(18:0) or 1-Octadecanoyl-glycerone-3-phosphate is the precursor to 1-Octadecyl-glycerone-3-phosphate DHAP(18:0e) which is generated via alkylglycerone phosphate synthase (EC: 2.5.1.26). Ether lipids are lipids in which one or more of the carbon atoms on glycerol is bonded to an alkyl chain via an ether linkage, as opposed to the usual ester linkage. Ether lipids are called plasmalogens (1-O-1-alkenyl-2-acylglycerophospholipids) if these are glycerol-containing phospholipids with an unsaturated O-(1-alkenyl) (vinyl ether) group at the first position on the glycerol chain. Plasmalogens as well as some 1-O-alkyl lipids are ubiquitous and sometimes major parts of the cell membranes in mammals and anaerobic bacteria. In archaea, ether lipids are the major polar lipids in the cell envelope and their abundance is one of the major characteristics that separate this group of prokaryotes from the bacteria. In these cells, diphytanylglycerolipids or bipolar macrocyclic tetraethers can form covalently linked bilayers. [HMDB] DHAP(18:0) is the octadecanoyl derivative of dihydroxyacetone phosphate.

LysoPA(18:1(9Z)/0:0)

9-Octadecenoic acid (9Z)-, 2-hydroxy-3-(phosphonooxy)propyl ester

C21H41O7P (436.25897660000004)

LysoPA(18:1(9Z)/0:0) is a lysophosphatidic acid. It is a glycerophospholipid in which a phosphate moiety occupies a glycerol substitution site. Lysophosphatidic acids can have different combinations of fatty acids of varying lengths and saturation attached at the C-1 (sn-1) or C-2 (sn-2) position. Fatty acids containing 16 and 18 carbons are the most common. Lysophosphatidic acid is the simplest possible glycerophospholipid. It is the biosynthetic precursor of phosphatidic acid. Although it is present at very low levels only in animal tissues, it is extremely important biologically, influencing many biochemical processes. In particular, lysophosphatidic acid is an intercellular lipid mediator with growth factor-like activities, and is rapidly produced and released from activated platelets to influence target cells. 1-Palmitoyl lysophosphatidic acid is the major component of lysophosphatidic acid (LPA) in plasma, and is in a reduced ratio in individuals with gynecological cancers (PMID 11585410). LPA is a pluripotent lipid mediator controlling growth, motility, and differentiation, that has a strong influence on the chemotaxis and ultrastructure of human neutrophils (PMID 7416233). In serum and plasma, LPA is mainly converted from lysophospholipids, whereas in platelets and some cancer cells it is converted from phosphatidic acid. In each pathway, at least two phospholipase activities are required: phospholipase A1 (PLA1)/PLA2 plus lysophospholipase D (lysoPLD) activities are involved in the first pathway and phospholipase D (PLD) plus PLA1/PLA2 activities are involved in the second pathway.
