[f. oligo- + -mer.]
Any polymer whose molecules consist of relatively few repeating units.
1952van der Want & Staverman in Rec. Trav. Chim. Pays-Bas LXXI. 379 In the course of an investigation into the chemical and physical properties of polymers of different molecular weight it appeared desirable to us to have available condensation products of ε- amino-caproïc acid: H[NH(CH2)5CO]nOH with low and exactly specified values of n (‘linear oligomers’) e.g. n = 2, 3, 4 and 5. 1967[see leucoanthocyanidin s.v. leuco-]. 1969Nature 13 Sept. 1125/2 Table 1 shows the frequencies of monomers, dimers and higher oligomers of mitochondrial DNA. 1975Ibid. 6 Mar. 83/2 The extent to which each of the characteristic oligomers (pentanucleotides and larger) of Escherichia coli 16S rRNA is conserved across phylogenetic lines.
Hence oligoˈmeric a.
1957Makromolekulare Chemie XXIII. 32 The van der Wyk-rule, which permits calculation of the melting points of straight-chain paraffins, can be applied to the oligomeric esters of terephthalic acid and glycol after introduction of suitable constants. 1970Nature 13 June 1004/2 A series of oligomeric substrates, up to twelve glucose units in length and labelled at the end-group, was prepared. 1974Sci. Amer. Nov. 64/1 The J chain is present in oligomeric forms, and the dimer, when found in secretions such as saliva and tears, is bonded to yet another polypeptide. |
