Novel amino-acids and their derivatives of the Formula I: wherein X denotes H or halogen, R denotes -OH, -OC 1-4 alkyl, (where R 1 and R 2 independently denote H, C 1-4 alkyl or a cyclic radical, e.g. phenyl or pyridyl, optionally substituted by one or more halogen atoms, a...
no study has used nanopores to achieve simultaneous sensing of unnatural amino acids and their corresponding natural amino acids. In our study, we conducted experiments involving cysteine and CMC (Fig.4c), and found that the CMC signals exhibited blockades that were notably different from those of...

A good source of omega-3 fatty acids, including alpha-linolenic acid (ALA) such as flaxseed, chia seeds, hemp seeds, walnuts, and their oils, should be included in the diet of vegetarians, whereas those with increased requirements, such as pregnant and lactating individuals or patients with ...
where enantiomeric pairs differ only in that their two structures are nonsuperimposable mirror images of each other1. Only pure enantiomeric (homochiral) structures for materials and medicinal drugs tend to be active in having their desired optical, mechanical, and therapeutic properties, whereas enant...
