“…For the protonated lysyl side-chain, values of C p ðlysH þ Þ at all temperatures in the range T = (288.15 to 328.15) K were obtained by the addition to the quantities fC p ðlysH þ ÞÀ C p;2 ðH þ Þg reported previously [8], a value for C p;2 ðH þ Þ of À63. 5 ± 5 J AE K À1 AE mol À1 , which is an average of the four values determined previously [31] at T = (288.15, 298.15, 313.15, and 328.15) K.…”
