Despite the detection of amino acids, the building blocks of the proteins that support life, in cometary and meteoritic samples, we do not yet understand the conditions under which these life-essential species have formed. Hydroxylamine (NH$_2$OH) is potentially a direct precursor to the formation of the amino acids glycine and alanine in the ISM, through reaction with acetic and propionic acids. Recent laboratory and modeling work has shown that there are a variety of pathways to the formation of NH$_2$OH in interstellar ices both efficiently and in high abundance. Here, we present the result of a deep, multi-telescope search for NH$_2$OH in the shocked, complex molecular source L1157. We find no evidence suggesting the presence of thi...
