Additional conventions used in describing higher order data include, for example, the designation of peaks in COSY spectra: Man H-1,2; HOHAHA tracking: GlcNAc H-2,3,4,5,6a,6b etc.; NOE contacts: Glc H-1, Xyl H-4,5e, etc. For designating resonances in oligosaccharides, the sugar units should be numbered with Roman numerals I, II, III, etc. beginning at the reducing(“upstream”) end of the molecule. (See IUPAC Nomenclature for Carbohydrates, 2-CARB-.)The individual resonances are numbered with Roman numeral superscripts as, for example, the following: H-3 I , H-3 II , H-3 III .
Design drew much commentary. One colleague described the GLC like a “prestige car that had a been Xeroxed too many times, losing its premium-ness in the process”. Indeed, when the S-Class design was robbed blind for the current C-Class, it brought a newfound freshness to the upmarket mid-sized sedan and wagon segment. That the GLC in turn robbed C-Class down to fine detail has left the mid-size SUV feeling a little seen-it-all-before, a new segment challenger dulled somewhat from being a bit predictable and Benz-by-the-numbers. Being something of a ‘safe haven’, though, ought not affect the GLC’s ratings here.
