A carbon atom has the four valence electrons and so it can attach to four atoms at a given time. When such a carbon atom is attached to four different groups at the same time, this carbon atom is known as a chiral carbon or asymmetric carbon. This atom has a center through which it ...

At higher temperatures, they shift to a different phase (known as chiral/cholesteric), and start to show shifting colors (sometimes called "color play") as they get hotter. At a certain higher temperature, known as the clearing point, the molecules stop behaving like liquid crystals altogether...
Glycolysis is the process of breaking glucose down into energy to be used by the body. Explore the two steps in this metabolic process and learn about the citric acid cycle, also known as the Krebs cycle, which also breaks down molecules for energy. Related...
The stereoisomer count of a molecule can be predicted from its atomic connectivity by identifying the chiral centers. Stereoisomerism has been used in drugs and chemical laboratories to synthesize new chemicals and medicine. Answer and Explanation:1 ...
Swapping any two groups on a chiral center inverts its absolute configuration (RtoS,StoR): Notice that these are different molecules. We are not talking about rotating about an axis or a single bond, in which case the absolute configuration(s) must stay the same. We are actually converting ...
(4) refers to chiral centers (5) states that R > S P-92.4 explains "rule (3)" in detail and states again that "seqcis" = "Z" and "seqtrans" = "E" and states that Z and E are PIN (Preferred IUPAC Nomenclature) and states that ...
molecules. In the first half of this chapter, we review the fundamentals of membrane curvature generation and the various strategies recently used to mimic this membrane activity of AMPs using different classes of synthetic molecules. In the second half, we show that it is possible to impart ...
In this phase, the molecules twist slightly from one layer to the next, resulting in a spiral formation. Ferroelectric liquid crystals (FLCs) use liquid crystal substances that have chiral molecules in a smectic C type of arrangement because the spiral nature of these molecules allows the micro...
