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 found2-Methyl-3-(3-methyl-2-butenyl)naphthoquinoneLepachol acetateLepachol acetic acidVitamin MK 1C16H18O2242.3129242.130679824-hydroxy-3-methyl-2-(3-methylbut-2-en-1-yl)-1,4-dihydronaphthalen-1-one4-hydroxy-3-methyl-2-(3-methylbut-2-en-1-yl)-4H-naphthalen-1-oneCC(C)=CCC1=C(C)C(O)C2=CC=CC=C2C1=OInChI=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,9H2,1-3H3PXIPYHVOWDEAMD-UHFFFAOYSA-NInner membraneMembraneOuter membranelogp2.97logs-3.36solubility1.05e-01 g/llogp3.06pka_strongest_acidic13.62pka_strongest_basic-3.4iupac4-hydroxy-3-methyl-2-(3-methylbut-2-en-1-yl)-1,4-dihydronaphthalen-1-oneaverage_mass242.3129mono_mass242.13067982smilesCC(C)=CCC1=C(C)C(O)C2=CC=CC=C2C1=OformulaC16H18O2inchiInChI=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,9H2,1-3H3inchikeyPXIPYHVOWDEAMD-UHFFFAOYSA-Npolar_surface_area37.3refractivity74.62polarizability27.77rotatable_bond_count2acceptor_count2donor_count1physiological_charge0formal_charge0Specdb::CMs1084355Specdb::NmrOneD264808Specdb::NmrOneD264809Specdb::NmrOneD264810Specdb::NmrOneD264811Specdb::NmrOneD264812Specdb::NmrOneD264813Specdb::NmrOneD264814Specdb::NmrOneD264815Specdb::NmrOneD264816Specdb::NmrOneD264817Specdb::NmrOneD264818Specdb::NmrOneD264819Specdb::NmrOneD264820Specdb::NmrOneD264821Specdb::NmrOneD264822Specdb::NmrOneD264823Specdb::NmrOneD264824Specdb::NmrOneD264825Specdb::NmrOneD264826Specdb::NmrOneD264827Specdb::MsMs27560Specdb::MsMs27561Specdb::MsMs27562Specdb::MsMs34118Specdb::MsMs34119Specdb::MsMs3412025200371CPD0-1367Keseler, I.
