WebJun 9, 2024 · In the knot theory lessons (and in wikipedia) it is stated that "The Alexander polynomial cannot detect the chirality", and it may be the case, but what worries me is that it is sometimes deduced right afted showing that Δ ( K) = Δ ( K ∗), where K ∗ is the mirror image of the knot K. WebHere we find that the chemical found in the rods and cones of our eyes, retinal, can have cis and trans isomers and it is the inter-conversion between these which allows us to detect light: Figure 1. The conversion of the cis isomer, A, to the trans isomer, B, occurs when the chemical is exposed to light.
WebCis and trans double bonds are sterogenic centers in that two different compounds are possible that are stereoisomers (diasteromers). However, that is not sufficient. You must have two cumulated alkenes (c=c bonds next to each other) with at least 2 substituents to have "axial" chirality. There is also helical chirality.
