Progress in Physical Organic Chemistry
The compounds show a preferentially polyenic behavior, but one can see slight
changes toward polymethinic properties which obviously result from a partial
localization of the 71-electrons at the heteroatoms. in consequence, the chain is
in a ...

82 (degree of double bond saturation in the polyenic chain), defined as 1 if a
double bond of the polyenic chain is saturated or as 0 for uninterrupted
conjugation of the polyenic chain 3. 83 (possibility of the end group being
transformed into a ...

Animal experiments have shown that the requirement for vitamin E depends on
the alimentary intake of multiply unsaturated fatty acids (polyenic acids); the latter
increase the requirement for vitamin E. However, it is known that foods which ...

Toxicants Occurring Naturally in Foods
It is known from many publications that an elevated intake of polyenic acids by
animals causes an increased need for vitamin E. This antagonism could have at
least two causes. The vitamin E might be acting as a natural antioxidant to protect
...

Furthermore, experimental and theoretical studies showed that the magnitude of
β as well as the difference between the ground and excited state dipole moment
is enhanced with the increase of the oligomer size for some polyenic compounds

Analytical Archaeometry: Selected Topics
Parrodienes (or psittacofulvins) are actually polyenes, i.e. polyunsaturated
organic compounds that contain one or more sequences of alternating single and
double carbon–carbon bonds (named polyenic chain) as well as varied
substitutions ...

NMR studies yield indication on the bond length alternation in the polyenic chain,
a structural parameter proportional to the MIX parameter for the special case of
push-pull polyenes (26). via the determination of the coupling constants between
...

ADVANCES IN APPLIED MICROBIOLOGY
The inhibitory action of polyenic macrolides arises from their ability to complex
with sterols (Gottlieb et al., 1958; Lampen, 1966). Complexing is attributed to
hydrophobic interactions between the nonpolar region of the sterol and the
nonpolar ...

As 8 increases, e.g., when switching from a purely polyenic backbone as in
polyacetylene, to a mixed aromatic-polyenic backbone as in poly(p-
