Fructo-oligosaccharide DP10/GF9 belongs to fructooligosaccharides (FOS) with degree of polymerization (DP=10). Fructo-oligosaccharides (FOS) are composed of 9 fructose units linked by (2→1)-β-glycosidic bonds and having a single D-glucosyl unit at the non-reducing end.

2-(5-methyl-1H-imidazol-4-yl)ethan-1-amine hydrochloride is a compound used as a molecular building block.

p-Cresol (4-methylphenol) is a partially lipophilic moiety which strongly binds to plasma protein (close to 100%) under normal conditions. p-Cresol is metabolized through conjugation mainly sulphation and glucuronization but removal of the unconjugated p-cresol is at least in part via the urine.
