The composition of the interstellar dust remains controversial .The 10µm absorption feature has been analyzed in terms of silicate for a long time, In this paper we had compared between absorption toward the galaxy M82 and infrared spectra of organic and biological materials. We obtained a good agreement relatively with spectrum of Murchison meteorite. This meteorite composition contains organic and amino acids components which are the basis of DNA of the cells.
