UnidentifiedHidden/hexopyranose_stereoisomers
收藏资源简介:
该数据集包含所有32种六吡喃糖立体异构体(`OCC1OC(O)C(O)C(O)C1O`)的DFT优化3D几何结构,这是一种具有5个立体中心的六元糖环。它专为需要精细立体化学区分的分子嵌入方法(如库仑矩阵和键袋表示)的基准测试而设计。每个异构体有两种椅式构象(Chair1和Chair2),所有64种结构均在DFT级别进行了优化,并通过频率分析验证为真实最小值。数据集还包括用于分子嵌入生成的最稳定椅式构象,以及包含SMILES、立体键、能量等信息的摘要表格。
This dataset contains DFT-optimized 3D geometries for all 32 stereoisomers of hexopyranose (`OCC1OC(O)C(O)C(O)C1O`), a six-membered sugar ring with 5 stereocenters. It is designed for benchmarking molecular embedding methods that require fine stereochemical discrimination, such as the Coulomb Matrix and Bag of Bonds representations. Each isomer has two chair conformations (Chair1 and Chair2), and all 64 structures were optimized at the DFT level and verified as true minima via frequency analysis. The dataset also includes the most stable chair conformation for each stereoisomer for molecular embedding generation, as well as summary tables with SMILES, stereokeys, energies, and other information.
