Autor: Hroboňová Katarína, Lehotay Jozef, Čižmárik Jozef

Publikováno v: Nova Biotechnologica et Chimica, Vol 15, Iss 1, Pp 12-22 (2016)

The HPLC by using chiral stationary phases based on macrocyclic antibiotics, dimethylphenyl carbamate cyklofructan 7 and β-cyclodextrin in terms of polar-organic separation mode (mobile phase methanol/acetonitrile/acetic acid/triethylamine) were use

In Vitro Investigation of D- and Lenantiomer Synergistic Efects of Some Amino Acids

Autor: Bystrická Zuzana, Lehotay Jozef

Publikováno v: Nova Biotechnologica et Chimica, Vol 15, Iss 1, Pp 47-54 (2016)

D-amino acids can arise from endogenous microbial flora, from ingestion with the diet or from spontaneous racemization of L-amino acids during ageing. In this work, the behavior of methionine, homocysteine and cysteine enantiomers was investigated in

Separation Of Methionine Enantiomers By Using Teicoplanin And Cyclofructan Columns

Autor: Hroboňová Katarína, Deáková Zuzana, Moravčík Jakub, Lehotay Jozef, Armstrong Daniel W., Lomenová Anna

Publikováno v: Nova Biotechnologica et Chimica, Vol 14, Iss 1, Pp 1-11 (2015)

Methionine is a naturally occurring amino acid. Its enantiomeric separation by using high performance liquid chromatography on various types of chiral stationary phases was studied. The effect of mobile phase composition on enantioselectivity and ret
