A beta hairpin is a common supersecondary motif composed of two anti-parallel beta strands connected by a loop. The structure resembles a hairpin and is often found in globular proteins. The loop between the beta strands can range anywhere from 2 to 16 residues. However, most loops contain less than seven residues. [2]
The secondary structure of a β-sheet can be described roughly by giving the number of strands, their topology, and whether their hydrogen bonds are parallel or antiparallel. β-sheets can be open , meaning that they have two edge strands (as in the flavodoxin fold or the immunoglobulin fold ) or they can be closed β-barrels (such as the TIM ...

This theory of personality factors and the self-report instrument used to measure them are known respectively as the 16 personality factor model and the 16PF Questionnaire (16PF). [ 16 ] Cattell also undertook a series of empirical studies into the basic dimensions of other psychological domains: intelligence , [ 17 ] motivation , [ 18 ] career ...
