WebApr 10, 2024 · l-Threonine aldolases (LTAs) are attractive biocatalysts for synthesizing β-hydroxy-α-amino acids (HAAs) via C–C bond formation in pharmaceuticals, although their industrial applications suffer from low activity and diastereoselectivity. Herein, we describe the discovery of a new LTA from Neptunomonas marine ( Nm LTA) that displays both … WebThe most important organic chemistry concepts. In organic compounds, C-C single bond is always a sigma bond. In the C=C double bond, the first bond is always a sigma bond, while the second is a pi bond. If a carbon atom is bonded to 2 other C-atoms, it must then have 2 H-atoms to complete its valency of 4 and attain a stable octet electronic ... WebReactions of Aromatics:EAS and Beyond 0m. 19.
