DCPA degrades via successive hydrolysis of the two ester linkages, first forming monomethyl tetrachloroterephthalate ( MTP ) then further to tetrachloroterephthalic acid ( TPA ).

Choline in food exists in either a free or esterified form ( choline bound within another compound, such as phosphatidylcholine, through an ester linkage ).
13.
"' Transesterification "': An alcohol-terminated oligomer and an ester-terminated oligomer condense to form an ester linkage, with loss of an alcohol.

The two reverse ester linkages in the bridge between the two isoquinolinium groups make atracurium and cisatracurium poor targets for plasma cholinesterase, unlike mivacurium which has two conventional ester linkages.

Polyphenols always have heteroatom substituents other than hydroxyl groups; ether and ester linkages are common, as are various carboxylic acid derivatives ( see theaflavin gallate image ); ester linkages are common in the hydrolyzable tannins.

The exact mechanism of action is unknown at this time but the 3'position contains an amide linkage instead of the normal ester linkage of tRNA . That makes the molecule much more resistant to hydrolysis and stops the ribosome.
19.
Ether linkages are more chemically stable than the ester linkages found in Bacteria and Eukarya, which may be a contributing factor to the ability of many Archaea to survive in extreme environments that place heavy stress on cell membranes, such as extreme heat and salinity.
20.
C4 is homologous to C3 in that it contains an internal thioester bond that ends up on C4b and thus it can form covalent amide or ester linkages with the plasma membrane membrane of the pathogen and any associated antibodies, where it then behaves as an opsonin.
