Menaquinones and demethylmenaquinones are isoprenoid quinones of the naphthalene series, and are constituents of bacterial plasma membranes, where they play important roles in electron transfer and oxidative phosphorylation. Menaquinones or Vitamin K2 homologs are characterized by the number of isoprenoid residues in their side chain. Menaquinones are abbreviated MK-n, where n represents the number of isoprenoid side chain residues. For example, menaquinone-4 (abbreviated MK-4), has four isoprene residues in its side chain. The most common length of the side chain in bacteria is 8, although minor amounts of MK-1 through MK-14 have been found 2-Methyl-3-(3-methyl-2-butenyl)naphthoquinone Lepachol acetate Lepachol acetic acid Vitamin MK 1 C16H18O2 242.3129 242.13067982 4-hydroxy-3-methyl-2-(3-methylbut-2-en-1-yl)-1,4-dihydronaphthalen-1-one 4-hydroxy-3-methyl-2-(3-methylbut-2-en-1-yl)-4H-naphthalen-1-one CC(C)=CCC1=C(C)C(O)C2=CC=CC=C2C1=O InChI=1S/C16H18O2/c1-10(2)8-9-12-11(3)15(17)13-6-4-5-7-14(13)16(12)18/h4-8,15,17H,9H2,1-3H3 PXIPYHVOWDEAMD-UHFFFAOYSA-N Inner membrane Membrane Outer membrane logp 2.97 ALOGPS logs -3.36 ALOGPS solubility 1.05e-01 g/l ALOGPS logp 3.06 ChemAxon pka_strongest_acidic 13.62 ChemAxon pka_strongest_basic -3.4 ChemAxon iupac 4-hydroxy-3-methyl-2-(3-methylbut-2-en-1-yl)-1,4-dihydronaphthalen-1-one ChemAxon average_mass 242.3129 ChemAxon mono_mass 242.13067982 ChemAxon smiles CC(C)=CCC1=C(C)C(O)C2=CC=CC=C2C1=O ChemAxon formula C16H18O2 ChemAxon inchi InChI=1S/C16H18O2/c1-10(2)8-9-12-11(3)15(17)13-6-4-5-7-14(13)16(12)18/h4-8,15,17H,9H2,1-3H3 ChemAxon inchikey PXIPYHVOWDEAMD-UHFFFAOYSA-N ChemAxon polar_surface_area 37.3 ChemAxon refractivity 74.62 ChemAxon polarizability 27.77 ChemAxon rotatable_bond_count 2 ChemAxon acceptor_count 2 ChemAxon donor_count 1 ChemAxon physiological_charge 0 ChemAxon formal_charge 0 ChemAxon Specdb::CMs 1084355 Specdb::NmrOneD 264808 Specdb::NmrOneD 264809 Specdb::NmrOneD 264810 Specdb::NmrOneD 264811 Specdb::NmrOneD 264812 Specdb::NmrOneD 264813 Specdb::NmrOneD 264814 Specdb::NmrOneD 264815 Specdb::NmrOneD 264816 Specdb::NmrOneD 264817 Specdb::NmrOneD 264818 Specdb::NmrOneD 264819 Specdb::NmrOneD 264820 Specdb::NmrOneD 264821 Specdb::NmrOneD 264822 Specdb::NmrOneD 264823 Specdb::NmrOneD 264824 Specdb::NmrOneD 264825 Specdb::NmrOneD 264826 Specdb::NmrOneD 264827 Specdb::MsMs 27560 Specdb::MsMs 27561 Specdb::MsMs 27562 Specdb::MsMs 34118 Specdb::MsMs 34119 Specdb::MsMs 34120 25200371 CPD0-1367 Keseler, I.
