The average degree of condensation of ethylene oxidejtert-octylphenol condensate surfactants can be estimated rapidly by U.V. and i.r. spectrometry. The U.V. method is based on evaluating the specific absorptivity, a, at 275 nm in aqueous ethanol (60:40 v/v), and inserting this value in equations ob

Tripeptidesserve as model systems for understanding the so-called random-coil state of peptides and proteins. While it is well known that polyproline or proline-rich polypeptides adopt the very regular polyproline-II (PPII) or left-handed 3(1)-helix conformation, it was thus far not clear whether th
