Abstract

In this work it is shown using spectral-luminescent methods that eosin and anthracene bind to human serum albumin globules. Comparison of eosin lifetimes in water, propyl alcohol and human serum albumin allows to establish that probability of the processes of nonradiating deactivation of eosin triplets decreases when eosin is bound to protein. It is shown that molecules of energy donor (eosin) and acceptor (anthracene) in protein globule can be localized on the distance of electron clouds overlapping and as a result triplet-triplet energy transfer occurs.
