This study describes chirality‐ or template‐mediated helicalinduction in achiral β‐peptides for the first time. A strategy of end capping β‐peptides derived from β‐hGly (the smallest achiral β‐amino acid) with a chiral β‐amino acid that possesses a carbohydrate side chain (β‐Caa; C‐linked carbo β‐amino acid) or a small, robust helical template derived from β‐Caas, was adopted to investigate folding

TPP oligonucleotides: Hybridization probes that interrogate target sequences through base pairing, stacking on the terminus, and binding in the minor groove are presented (see figure). All subunits of the probes contribute to the target affinity, leading to melting point increases of up to 45 °C. (TPP=three‐pronged probe)
