Tricresyl phosphate, isomers, “free of o-isomers” [PDF]

open access: yes, 2023
The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has evaluated tricresyl phosphate, isomers [1330-78-5], “free of o-isomers” considering all toxicological end points. The para and meta isomers do not cause severe effects on the CNS.

Itaconate Isomers in Bread

open access: yesAntioxidants, 2022
The naturally occurring isomers itaconate, mesaconate and citraconate possess immunomodulatory, antioxidative and antimicrobial properties. However, it is not known whether they occur in commonly consumed human foods. Considering that they can arise as a result of heat conversion, we tested whether they occur in bread, representing a commonly consumed ...

Identification of novel high mannose N-glycan isomers undescribed by current multicellular eukaryotic biosynthetic pathways [PDF]

open access: yes, 2022
N-linked glycosylation is one of the most important post-translational modifications of proteins. Current knowledge of multicellular eukaryote N-glycan biosynthesis suggests high mannose N-glycans are generated in the endoplasmic reticulum and Golgi ...

Optically distinguishable electronic spin isomers of a stable organic diradical [PDF]

open access: yes, 2023
Herein, we demonstrate a model of electronic spin isomers, the electronic counterpart of nuclear spin isomers, by employing a through-space conjugated stable organic diradical. We investigated a benzotriazinyl radical dimer linked via triptycene skeleton.

Comonomer Isomers Result in Varied Optical Properties for Long Wavelength Infrared-Transmitting ORMOCHALC Polymers [PDF]

open access: yes, 2023
Inverse vulcanization is a method by which sulfur is combined with comonomer molecules to develop stable materials termed organically modified chalcogenide (ORMOCHALC) polymers.

Overview of Seniority Isomers [PDF]

open access: yes, 2022
Nuclear isomers are the metastable excited states of nuclei. The isomers can be categorized into a few classes including spin, seniority, K, shape and fission isomers depending upon the hindrance mechanisms.

Isomeric 4,2′:6′,4″- and 3,2′:6′,3″-Terpyridines with Isomeric 4′-Trifluoromethylphenyl Substituents: Effects on the Assembly of Coordination Polymers with [Cu(hfacac)2] (Hhfacac = Hexafluoropentane-2,4-dione)

open access: yesInorganics, 2021
The isomers 4′-(4-(trifluoromethyl)phenyl)-4,2′:6′,4″-terpyridine (1), 4′-(3-(trifluoromethyl)phenyl)-4,2′:6′,4″-terpyridine (2), 4′-(4-(trifluoromethyl)phenyl)-3,2′:6′,3″-terpyridine (3), and 4′-(3-(trifluoromethyl)phenyl)-3,2′:6′,3″-terpyridine (4 ...

High Percentage of Isomeric Human MicroRNA and Their Analytical Challenges

open access: yesNon-Coding RNA, 2016
MicroRNA (miR) are short non-coding RNAs known to post-transcriptionally regulate gene expression, and have been reported as biomarkers for various diseases. miR have also been served as potential drug targets.
