- W1538614875 abstract "The temperature dependence of UV absorption and ORD spectra and the polarographic behavior of poly(A) solutions at pH 4.9 and high ionic strength (0.5 – 4.2m [Na+]) was studied. With increasing ionic strength and temperature aggregation appeared, manifested by a decrease in ϵmax, an apparent increase in absorbance above 300 nm, a decrease of optical activity and decrease of the polarographic wave. The aggregation at high ionic strength seems to be caused by reduced repulsion between phosphate groups of the poly(A) chains, while the aggregation at high temperature to the liberation and reassociation of hydrophobic groups in mycels. In the ionic strength range between 2.7 and 3.1 m [Na+] a transition has been observed which is interpreted as uncharged double stranded poly(A). Above 3.1 m [Na+] the existence of uncharged double stranded poly(A)·poly(A)3, in addition to the normally existing forms poly(A) and poly(A+)·poly(A+) in the partially insoluble mycel structures appears possible and its implications are discussed. Titration experiments also indicate that at high ionic strength the protonation is not the primary factor in the stabilisation of double stranded poly(A), but that the shielding of the charges on the phosphate groups by the counterions is mainly responsible for the stability of this structure. Still a very small amount of protonation (α = 0.1) appears to be necessary." @default.
