Glycine, interstellar clouds

Today it is impossible to say whether prebiological evolution may have occurred in space, but for the moment there is no reason to exclude this option. Whatever hypotheses are retained, they must surely focus on the warmer regions (if we may use this word ) of the interstellar clouds, the very regions where star formation occurs. However, intense astrophysical searches for the simplest amino acid, glycine (NH2CH2COOH), in the dense cores of interstellar clouds have so far failed. 

The use of telescopic spectroscopy has revealed the existence of glycine in interstellar dust clouds. Since these clouds amount to huge masses of matter (greater than the total mass of condensed objects such as stars and planets), there must be universal availability of amino acids, even though they are dispersed thinly in the vast volume of space.
