  • Measuring the extent of glutamine deamidation could enable researchers to date artifacts back 1,000,000 years, well beyond carbon dating's horizon, Wess says.

Examples

  • What's really exciting, Wess says, is the possibility, hinted at in the York group's paper, that researchers could use glutamine deamidation to date collagen-based artifacts, such as bone or parchment.

  • To determine the extent of deamidation, the team compared peaks for glutamine and glutamic acid in the data.

  • Researchers conducted a study on deamidation to understand how proteins change over time.

  • The process of deamidation can affect the stability of proteins used in pharmaceuticals.

  • In food science, deamidation of proteins can influence the texture and flavor of products.

deamidation singular

Morphology

deamidation = deamidate (semi-transparent) = de + amide + ation

Formed by a regular nominalization (-ation) from the verb 'deamidate', so the step from the immediate base to the noun is a routine morphological process.

Etymology

Deamidation breaks into de- meaning 'remove' and amide, a 'part' found in proteins and in 'amino acids', so it means removing or changing that amide part of a molecule. That's why deamidation describes a chemical change in proteins that can change how they work.
