Glycolaldehyde is the simplest of the monosaccharide sugars and is directly linked to the origin of life. We report on the detection of glycolaldehyde (CH2OHCHO) toward the hot molecular core G31.41+0.31 through IRAM PdBI observations at 1.4, 2.1, and 2.9 mm. The CH2OHCHO emission comes from the hottest (⩾ 300 K) and densest (⩾ 2 × 108 cm−3) region closest (⩽ 104 AU) to the (proto)stars. The comparison of data with gas-grain chemical models of hot cores suggests for G31.41+0.31 an age of a few…

ON THE FORMATION OF GLYCOLALDEHYDE IN DENSE MOLECULAR CORES
Glycolaldehyde is a simple monosaccharide sugar linked to prebiotic chemistry. Recently, it was detected in a molecular core in the star-forming region G31.41+0.31 at a reasonably high abundance. We

Widespread Presence of Glycolaldehyde and Ethylene Glycol around Sagittarius B2
TLDR
The detection of widespread CH2OHCHO and HOCH2CH2OH emission in Galactic center giant molecular cloud Sagittarius B2 using the Shanghai Tianma 65 m Radio Telescope strongly support the existence of abundant prebiotic molecules in ices.
The Submillimeter Spectrum of Glycolaldehyde
Glycolaldehyde (HOCH2CHO) is a sugar-related interstellar prebiotic molecule that has been detected in two star-forming regions, Sgr B2(N) and G31.41+0.31. Glycolaldehyde is suspected to form from

GLYCOLALDEHYDE FORMATION VIA THE DIMERIZATION OF THE FORMYL RADICAL
Glycolaldehyde, the simplest monosaccharide sugar, has recently been detected in low- and high-mass star-forming cores. Following our previous investigation into glycolaldehyde formation, we now
Hydrogenation of glycolaldehyde to ethylene glycol at 10 K
Glycolaldehyde, the simplest sugar, is a complex organic molecule detected in many regions of the interstellar medium (ISM). Although its synthetic routes are fairly well known and consistent with
Tentative detection of ethylene glycol toward W51/e2 and G34.3+0.2
How complex organic - and potentially prebiotic - molecules are formed in regions of low- and high-mass star-formation remains a central question in astrochemistry. In particular, with just a few

VLA-C observations of thermal methanol toward the position of the G31.41+0.31 hot molecular core suggest that the outflow is oriented in the northeast-southwest direction, and the outflows is massive, with a dynamical time of the order of 4 × 103 yr, and has a wide-angle bipolar morphology.
