A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Application In Synthesis of H-HoPro-OH, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 3105-95-1, Name is H-HoPro-OH, molecular formula is C6H11NO2. In a Chapter, authors is Castro-Puyana, Maria，once mentioned of 3105-95-1

A high number of non-protein amino acids are chiral compounds that have demonstrated to be relevant in different fields. Their determination enables to obtain valuable information related to food quality and safety and has also a high interest from a biological point of view since many of them are key compounds in metabolic pathways or are related with different pathologies. In the development of analytical methodologies to perform chiral separations, capillary electrophoresis (CE) is well-established and one of the most powerful separation techniques as a consequence of its high efficiency, short analysis time, and versatility. This chapter shows, by means of three interesting examples, the application of different CE methodologies to the chiral analysis of non-protein amino acids. The first example describes different electrokinetic chromatography (EKC)-UV methodologies based on the use of negatively charged cyclodextrins as chiral selectors to carry out the stereoselective separation of ten different non-protein amino acids of relevance from a biological or food analysis point of view. The second method illustrates the EKC-UV analysis of l-citrulline and its enantiomeric impurity in food supplements using sulfated-gamma-cyclodextrin as chiral selector. The last example shows the simultaneous enantiomeric separation of 3,4-dihydroxy-dl-phenylalanine and all the other chiral constituents involved in the phenylalanine-tyrosine metabolic pathway by using an EKC-MS methodology.
