It is a glycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidylcholines can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PC(16:0/18:0), in particular, consists of one hexadecanoyl chain  to the C-1 atom, and one octadecanoyl  to the C-2 atom. In E. coli, PCs can be found in the integral component of the cell outer membrane. They are hydrolyzed by Phospholipases to a 2-acylglycerophosphocholine and a carboxylate.","experimental_water_solubility":null,"experimental_logp_hydrophobicity":null,"location":null,"synthesis_reference":null,"chebi_id":"18303","hmdb_id":"HMDB07970","kegg_id":"C00157","pubchem_id":"6323481","cs_id":"24766643","foodb_id":null,"wikipedia_link":"Lecithin","biocyc_id":"PHOSPHATIDYLCHOLINE","iupac":"(2-{[(2R)-3-(hexadecanoyloxy)-2-(octadecanoyloxy)propyl phosphono]oxy}ethyl)trimethylazanium","traditional_iupac":"(2-{[(2R)-3-(hexadecanoyloxy)-2-(octadecanoyloxy)propyl phosphono]oxy}ethyl)trimethylazanium","logp":"9.002933709194918","pka":null,"alogps_solubility":"2.17e-05 g/l","alogps_logp":"5.62","alogps_logs":"-7.58","acceptor_count":"4","donor_count":"0","rotatable_bond_count":"42","polar_surface_area":"111.19","refractivity":"225.06710000000007","polarizability":"95.55895667807658","formal_charge":"0","physiological_charge":"0","pka_strongest_basic":"-6.744159309169687","pka_strongest_acidic":"1.8550572064469137","bioavailability":"0","number_of_rings":"0","rule_of_five":"0","ghose_filter":"0","veber_rule":"0","mddr_like_rule":"0","synonyms":["1-palmitoyl-2-stearoyl-sn-glycero-3-phosphocholine","1,2-Diacyl-sn-glycero-3-phosphocholine","3-O-sn-Phosphatidyl-L-serine","3-sn-Phosphatidylcholine","Choline phosphatide","GPCho(16:0/18:0)","GPCho(34:0)","Lecithin","Lecithins","O3-Phosphatidyl-L-serine","PC(16:0/18:0)","PC(34:0)","Phosphatidyl-L-serine","phosphatidyl-L-serines","Phosphatidyl-N-trimethylethanolamine","Phosphatidylcholine","Phosphatidylcholine(16:0/18:0)","Phosphatidylcholine(34:0)"],"pathways":[{"name":"Arachidonic acid metabolism","kegg_map_id":"00590"},{"name":"Linoleic acid metabolism","kegg_map_id":"00591"},{"name":"alpha-Linolenic acid metabolism","kegg_map_id":"00592"},{"name":"Glycerophospholipid metabolism","kegg_map_id":"00564"},{"name":"Phosphatidylcholine biosynthesis PC(16:0/18:0)","kegg_map_id":null}],"growth_conditions":[],"references":[{"pubmed_id":19174513,"citation":"Ejsing, C.
