The Principles of Mechanics Presented in a New Form
A motion of a cyclical system in which its cyclical momenta remain constant is
called an adiabatic motion ; and when its cyclical intensities remain constant it is
called an isocyclic motion. The cyclical system itself is called adiabatic or
isocyclic ...

Complex Arithmetic Patterns Behind Numbers
If the ellipse is conceived as the section on the greatest and the least axes of an
ellipsoid of unit volume, the isocyclic diameters are the traces of the circular
sections of the ellipsoid. The coordinates of one of the points of intersection, say
E, ...

rin 9” to be the common precursor of hemes and of chlorophylls. The chlorophylls
contain a magnesium atom and an isocyclic ring; a compound of this kind is
magnesium vinyl pheoporphyrin (a,) (109) which, as phytyl ester, is
protochlorophyll.

The Chlamydomonas Sourcebook: Organellar and Metabolic Processes
Formation of the isocyclic ring of chlorophylls from the 13-methyl propionate in
most aerobic photosynthetic organisms is catalyzed by Mg-protoporphyrin IX
monomethyl ester oxidative cyclase. The cyclase step (Figure 20.1, step 12) is
among ...

In contrast, other oxidative reactions involving opening of the isocyclic ring or the
formation of a lactone ring do cause important changes in the electron absorption
spectrum. Figure 7.8 shows the specific differences between the spectrum of ...

Carbon and Its Domestication
2.2.2 Isocyclic (carbocyclic) compounds Isocyclic compounds contain ring
structures in which all the ring components are carbon atoms, as shown in Figure
2.1. There are millions of isocyclic compounds, including many naturally
occurring ...

Recently, we also gained access to 13'-oxophorbines, which are chlorins that
contain the isocyclic ring spanning the 13- and 15-positions (22). Chlorophylls a
and b also contain the 13]-oxophorbine skeleton. Chart 1 compares the
structures ...

Tetrapyrroles: Birth, Life and Death
The methyl propionate side-chain of MgPME is modified to form an isocyclic ring (
ring E). However, the cyclisation reaction is currently the most poorly understood
step in the pathway as the cyclase has never been purified and studied.
