Isomer in a sentence

A nonnative isomer of some peptide groups can disrupt the conformational folding significantly, either slowing it or preventing it from even occurring until the native isomer is reached.

Each isomer can be synthesized using the trans effect to control which isomer is produced.

In this conformation, the α-isomer has the -OH of the anomeric carbon in an axial position, whereas the β-isomer has the OH- of the anomeric carbon in equatorial position.

In this diagram, the α-isomer has the -OH of the anomeric carbon below the plane of the carbon atoms, and the β-isomer has the -OH of the anomeric carbon above the plane.

The branched isomer with the alcohol at a terminal carbon is isobutanol or 2-methyl-1-propanol, and the branched isomer with the alcohol at the internal carbon is tert-butanol or 2-methyl-2-propanol.

The D - isomer ( D -glucose), also known as dextrose, occurs widely in nature, but the L -isomer ( L -glucose ) does not.

This isomer is sometimes called the n-isomer (n for "normal", although it is not necessarily the most common).

While some chemists use the terms structural isomer and functional isomer interchangeably, not all structural isomers are functional isomers.

All "stable" isotopes (stable by observation, not theory) are the ground states of nuclei, with the exception of tantalum-180m, which is a nuclear isomer or excited state.

A mer isomer can be considered as a combination of a trans and a cis, since it contains both trans and cis pairs of identical ligands.

An isomer of tretinoin, isotretinoin is also used orally (under the trade names Accutane and Roaccutane), generally for severe or recalcitrant acne.

A nuclear isomer may also be called a " meta -state", meaning the system has more internal energy than the " ground state " (the state with the lowest possible internal energy), making the former likely to decay into the latter.

Appleton & Lange's 2003 Nursing Drug Guide, pp 177 The open chain opioids tend to have at least one isomer that is at some level a strong pure mu opioid receptor agent.

As an example of a geometric isomer due to a ring structure, consider 1,2-dichlorocyclohexane: Comparison of physical properties Cis and trans isomers often have different physical properties.

By definition, molecules that are stereoisomers of each other represent the same structural isomer.

Cells with colored borders (note the three bottom cells in the color legend at right) denote the half-life of the most stable nuclear isomer state.

Commercial production of retinol typically requires retinal synthesis through reduction of a pentadiene derivative and subsequent acidification/hydrolysis of the resulting isomer to produce retinol.

Frank B. Colton at Searle in Skokie, Illinois had synthesized the orally highly active progestins noretynodrel (an isomer of norethisterone) in 1952 and norethandrolone in 1953.

Gold's least stable isomer is mainAu with a half-life of only 7 ns.

Gold's most stable isomer is mainAu with a half-life of 2.27 days.
