Characterization of right-handed and left-handed shapes
Many natural shapes are chiral (or handed). Our hands, for example, have a righthand version and a left-hand version, the two types being mirror images of each other. Molecules are also classi ed according to their chirality, which determines their chemical characteristics. Glucose, for example, is sweet only in one chirality, while it is tasteless in the other. The notion of chirality for two ...
متن کاملA designed protein with packing between left-handed and right-handed helices.
A common motif in protein structures is the assembly of alpha-helices. Natural alpha-helical assemblies, such as helical bundles and coiled coils, consist of multiple right-handed alpha-helices. Here we design a protein complex containing both left-handed and right-handed helices, with peptides of D- and L-amino acids, respectively. The two peptides, D-Acid and L-Base, feature hydrophobic hepta...

متن کاملDifferences in body size between left-handed and right-handed Japanese professional baseball players
The present study investigated differences in height, weight, and body mass index (BMI) between left-handed and right-handed Japanese professional baseball pitchers and batters.
