1 [with object] Grammar Give the different forms of (a verb in an inflected language such as Latin) as they vary according to voice, mood, tense, number, and person: conjugating verbs forms part of language study
More example sentences

  • In a month, they were writing the alphabet, conjugating verbs, and making small sentences.
2 [no object] Biology (Of bacteria or unicellular organisms) become temporarily united in order to exchange genetic material: E. coli only conjugate when one of the cells possesses fertility genes
More example sentences
  • The phh1 single mutant is not completely sterile but is nearly sterile, whereas the msa1 deletion mutants conjugated efficiently even in nutrient-rich medium.
  • This is essential to the survival of ciliate lineages; most ciliates cannot reproduce indefinitely by asexual fission, and eventually die out if prohibited from conjugating.
  • The solid line designates a plasmid that conjugates slowly but imposes a low cost of carriage, whereas the dashed line indicates a faster-conjugating plasmid that imposes a higher cost.
2.1(Of gametes) become fused.
Example sentences
  • Under the same conditions, wild-type cells conjugated and succeeded in producing spores.
  • Haploid cells conjugated to form zygotes, which then underwent meiosis.
3 [with object] Chemistry Be combined with or joined to reversibly: bilirubin is then conjugated by liver enzymes and excreted in the bile
More example sentences
  • After estrone hydroxylation, the various poly-hydroxy derivatives are conjugated with glucuronate or sulfate, or methylation occurs prior to excretion in urine.
  • Fluorescein is frequently conjugated to macromolecules via lysine residues using an isothiocyanate derivative or to sulfhydryl groups via a variety of chemistries.
  • In the liver it is conjugated with glucuronate which renders it water soluble.

1Coupled, connected, or related, in particular:
Example sentences

  • The conjugate phrase, ‘operates to a significant extent for the benefit’, directs attention to certain features of the Trust.
  • The principles governing the seismic behavior of structures are the conjugate laws of equilibrium and compatibility, and force-displacement relationships of structural components.
1.1 Chemistry (Of an acid or base) related to the corresponding base or acid by loss or gain of a proton.
Example sentences
  • Of course, one can change the pH of the buffer by selecting other concentrations of acid and conjugate base, but the range of pH values over which a given buffer functions most effectively are close to the pK a of the acid.
  • The most common buffers are mixtures of weak acids and their conjugate bases.
  • In other words, the term pK a is that pH at which an equivalent distribution of acid and conjugate base (or base and conjugate acid) exists in solution.
1.2 Mathematics Joined in a reciprocal relation, especially having the same real parts and equal magnitudes but opposite signs of imaginary parts.
Example sentences
  • The quartic in y must factor into two quadratics with real coefficients, since any complex roots must occur in conjugate pairs.

1chiefly Biochemistry A substance formed by the reversible combination of two or more others.
Example sentences

2A mathematical value or entity having a reciprocal relation with another. See also complex conjugate.
Example sentences
