Megías, Á. López-Gallifa, A. Martínez-Henares, S. Massalkhi, B. Tercero, P. de Vicente, S. Martín, D. S. Andrés, M. A. Requena-Torres, and J. L. Alonso\\ reported on the\\ **[[https://doi.org/10.3847/2041-8213/ace977|First Glycine Isomer Detected in the Interstellar Medium: Glycolamide (NH2C(O)CH2OH)]]**\\ //Astrophys. J. Lett.// **953**, Art. No. L20 (2023).\\ The molecule was detected in the course of a molecular line survey of the Galactic Center molecular cloud G+0.693–0.027 employing the Yebes 40 m and IRAM 30 m radio telecopes. The transitions cover 31 to 98 GHz with 1 ≤ //J// ≤ 7 and //K<sub>a</sub>// ≤ 5. Some lines are unblended, slightly blended, or the peak of the line is at most slightly blended. Some further lines are blended more substantially. The glycolaldehyde/glycolamide ratio is ∼15, while the ethanol/ethanolamine ratio is ∼40.\\ \\ More recently,\\ C. Duan, F. Xu, Q. Gou, X. Xu, D. Quan, L. Pagani, X. Chen, J. Kang, and J. Du\\ announced the\\ **[[https://doi.org/10.1051/0004-6361/202659347|Tentative Detection of the Glycine Isomer Glycolamide in a Hot Molecular Core]]**\\ //Astron. Astrophys.// **709**, Art. No. A93 (2026).\\ Employing archival ALMA Band 7 data near of G358.93−0.03 MM1 near 300 GHz, the authors identified 7 unblended or slightly blended lines. The identitification was deemed tentative because of the small number of transitions and because severeal of these are close to the 3σ S/N limit. A rotational temperature of ~100 K was derived. Formamide and acetamide are more abundant by factors of about 32 and 17, respectively.\\ \\ ---- Contributor(s): H. S. P.
