Asymmetric synthesis, any chemical reaction that affects the structural symmetry in the molecules of a compound, converting the compound into unequal proportions of compounds that differ in the dissymmetry of their structures at the affected centre.
Hume considers Newton's second law of motion (F = ma) in the Enquiry, section 4, part 1 (EHU 4.13; SBN 31): "Thus, it is a law of motion, discovered by experience, that the moment or force of any body in motion is in the compound ratio or proportion of its solid contents and its velocity ….
Nearly all hit compounds maintained a proportion of GFP+ cells similar to that observed with DOX.
Consistent with effects of other HDACis, the compounds decreased the proportion of cells in the G1 and S phases of the cell cycle, associated with an accumulation of cells in G2M.
These are compounds whose proportions of elements do not stand in simple relations to one another.
The optimization problem has been formulated as a mixed-integer linear program, which is then solved using standard techniques to generate both the molecular structures of the compounds in the mixture and the proportion of each compound within that mixture.
If endogenous variation causes all compounds to vary as a simple multiple of the TA, then expressing each compound amount as a proportion of the TA for the sample is an unbiased estimator of relative abundances (RA).
Of the compounds 1– 4, compound 3 contains the highest proportion of long (4.0 5.5 Å) H··· Hcontacts due to the disordered nature of one propyl chain resulting in more space between adjacent Br atoms than for 1 or 2 (see Figure 4a).
One method expresses compound abundances as a proportion of the total abundance (TA) for a fly.
The proportion of compound in each state within the above-mentioned equilibrium depends strongly on the experimental conditions.
