Quinazolinamines are heterocyclic aromatic compounds containing a quianazoline moiety substituted by one or more amine groups. Arachin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Arachin can be found in peanut, which makes arachin a potential biomarker for the consumption of this food product. Kodashim or Kod'shim or Qodhashim (Hebrew: קדשים‎ "Holy Things") is the fifth Order in the Mishnah (also the Tosefta and Talmud). Of the six Orders of the Mishnah, it is the third longest. Kodoshim deals largely with the religious service within the Temple in Jerusalem, the qorbanot ("sacrificial offerings"), and other subjects considered or related to these "Holy Things" .
