The advantages claimed for hydrogen as an automobile fuel are the greater energy re-lease per unit weight of fuel and the absence of polluting emissions such as 0,C a . NO,. Sa,hydrocarbons. aldehydes and lead compounds. The product of combustion is water with ody traces of nitrogen oxides...
While the quality of the generated molecules indicate a high relevance of the proposed scoring function for de novo drug design, we furthermore qualitatively evaluated its usefulness to filter out undesirable compounds. This was studied especially in the light of existing rule-based approaches, such ...

Amine, any member of a family of nitrogen-containing organic compounds that is derived, either in principle or in practice, from ammonia (NH3). Naturally occurring amines include the alkaloids, which are present in certain plants; the catecholamine neuro
nonmetals, most commonly carbon (C) and hydrogen (H), which are always present; oxygen (O), nitrogen (N), sulfur (S) and phosphorus (P), which are commonly found; and chlorine (Cl), bromine (Br), iodine (I) and fluorine (F), which are present in other compounds (seeFig. 2.1)...
