WebN-acetylneuraminic acid (Neu5Ac) is one of the two most common sialic acid in mammals. It is a monosaccharide with a backbone of 9 carbons. It is usually attached to glycoproteins or gangliosides on a terminal end via α(2,3), α(2,6), and α(2,8) linkage. Neuraminidase is an enzyme which hydrolyses that bond to produce a free neuraminic acid and a glycoprotein … In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR)2 groups (where R = alkyl, aryl, or just hydrogen). Phosphonic acids, typically handled as salts, are generally nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and … See more Phosphonates feature tetrahedral phosphorus centers. They are structurally closely related to (and often prepared from) phosphorous acid. Phosphonate salts are the result of deprotonation of … See more Bisphosphonates Compounds containing 2 geminal phosphonate groups are known as bisphosphonates.

Bisphosphonates are a class of drugs that prevent the loss of bone density, used to treat osteoporosis and similar diseases. They are the most commonly prescribed drugs used to treat osteoporosis. They are called bisphosphonates because they have two phosphonate (PO(OH) 2) groups. They are thus also called diphosphonates (bis- or di- + phosphonate). WebMethylphosphonate(2-) is an organophosphonate oxoanion obtained by deprotonation of the phosphonate OH groups of methylphosphonic acid. It is a conjugate base of a methylphosphonate(1-). ChEBI. Methylphosphonate is a metabolite found in or produced by Escherichia coli (strain K12, MG1655).
