Abstract. 2-benzyloxy-1-methylpyridinium triflate (1) is emerging as a mild, convenient, and in some cases uniquely effective new reagent for the synthesis of benzyl. Collagen is the most abundant protein in animals. every third residue in a collagen strand is a glycine with ϕ, ψ = −70°, 175°. a recent computational study. Today, a wide variety of techniques is available for the preparation of (semi-) solid, liquid and gaseous samples, prior to their instrumental analysis by means of.
