Gangliosides (like GM1) - how to measure? Their sialic acid may be anti-inflammatory (and may be related to Glycanage). Is higher Glycanage predictive of reduced ganglioside synthesis?

During brain development, the ganglioside pattern changes from the prevalence of the simple gangliosides GM3 and GD3 to more complex ones such as GD1a and GT1b [66] (for structures, see Figures Figures77 and and11).11). Ganglioside content and composition of the brain change also during aging: for example, the amount of lipid-bound sialic acid decreased from 1070 μg/g wet weight in a 25-year-old healthy proband to 380 μg/g wet weight in a 85-year-old individual. Despite this, the concentrations of GQ1b, GT1b, and GD1b increase with age at the expense of GM1 and GD1a
