The most common stereocenters are chiral centers (such as asymmetric carbon atoms) and the double-bonded carbon atoms in cis-trans alkenes. A chiral center consists of an atom holding a set of ligands (atoms or groups of atoms) in a spatial arrangement which is not superposable on its mirror image.ost chiral molecules have a chiral carbon, though the presence of a chiral carbon does not necessarily make a molecule chiral (see meso compound). A chiral carbon is often denoted by C*. If the carbon is chiral, it follows that: 1  the carbon atom is sp 3 -hybridized;
Past the inca tunnel, a gentle climb will take you to the third pass at 12139 feet above sea level (3700 masl), offering incredible views of several snow capped peaks including Salkantay (20574 ft./6271m) and Veronica (18865 ft./5750m).
Some of the facts about this trail: Big Tree trail is about 0.8 miles long one way. It starts at about 1800 feet and descends to 1640 feet, making it only about 160 ft drop in elevation. This means that it is not that steep. It is a fairly easy trail, except for those steps, so it has a Moderate difficulty rating. The trail head is located at the large parking lot at KM 10.4 on Road 191.
