✦ Synopsis


A systematic study of the photoalkylation of amino acids by α-coupling products. Methionine was shown to be favoured both in the sense of reactivity as well as product stability. benzophenone, a standard photosensitive probe of biomolecules, was performed addressing for the first time chemo-, Preliminary to a project directed towards the elucidation of the topography of glycophorin A in membranes, the present regio-, and stereoselectivities. The high reactivity of the capto-dative substituted α-carbon, particularly in glycine, model experiments focussed on the ten amino acids that constitute the transmembrane part of this protein. could be demonstrated as well as the chemical lability of the
