Otolith microchemistry and diadromy in Patagonian river fishes.

abstract：:Elucidating the molecular mechanism of helix-coil transitions of short peptides is a long-standing conundrum in physical chemistry. Although the helix-coil transitions of poly-glutamic acid (PGA) have been extensively studied, the molecular details of its unfolding process still remain unclear. We performed all-atom c...
