In an article, author is Brand, Izabella, once mentioned the application of 70161-44-3, Name is Sodium 2-((hydroxymethyl)amino)acetate, molecular formula is C3H6NNaO3, molecular weight is 127.0744, MDL number is MFCD04307769, category is amides-buliding-blocks. Now introduce a scientific discovery about this category, Name: Sodium 2-((hydroxymethyl)amino)acetate.
Surface adsorption of a dipeptide L-alanyl-L-tryptophan (Ala-Trp) on gold nanoparticles reduced by citrate (CT) and borohydride (BH) ions was investigated by a surface-enhanced Raman scattering (SERS) technique. Two distinct SERS spectra of Ala-Trp depending on the types of gold nanoparticles were observed, and the vibrational assignments were based on the density functional theory simulations and the previous SERS results of Trp. Ala-Trp mainly adsorbs through the amine group on CT gold nanoparticles with a perpendicular orientation of the indole ring to the surface. In contrast, the adsorption occurs via the pi electrons of the indole ring on the BH gold surfaces while maintaining a flat geometry of the indole ring to the surface. The amide I band of Ala-Trp was observed only with the CT gold colloids in acidic and neutral conditions where partial surface adsorption via the amide group is expected. (C) 2020 Elsevier B.V.
