straight-chain

The name amyl alcohol referring to a distinct compound without further specification refers to the normal (straight-chain) form, 1-pentanol.

Olefins or alkenes, which are unsaturated straight-chain or branched hydrocarbons, do not occur naturally in crude oil.

Although this is not strictly necessary, the usage is common in cases where there is an important difference in properties between the straight-chain and branched-chain isomers.

The mass spectra of trimethylene- and tetramethylenesilyl ethers derived from isomeric straight-chain and branched alcohols differ quantitatively.

Characterization of the extract by gas–liquid chromatography – mass spectrometry reveals it is mainly composed of a mixture of odd- and even-numbered straight-chain, saturated hydrocarbons (C25 to C34).

The difference between (straight-chain) fatty acid synthase and branch-chain fatty acid synthase is substrate specificity of the enzyme that catalyzes the reaction of acyl-CoA to acyl-ACP.

When tested for thresholds to the odors of a series of straight-chain (aliphatic) aldehydes, dogs do better on the short chain compounds, but humans perform as well or slightly better than dogs on the longer chain compounds, and humans perform significantly better than rats (Laska et al. 2000).
