When it is inhaled or its salts are ingested in high amounts, [ clarification needed ] damage to organs occurs rapidly with symptoms ranging from breathing difficulties to convulsions and death.
Hace 14 horas · Sulfur-containing organic molecules are essential for life on Earth as they are crucial for many biological processes, such as protein structure and function, enzyme activity, and cellular respiration to incorporate sulfur. These organic molecules were created in laboratory simulations that mimic the conditions of interstellar ices found in space.
Hace 14 horas · Structure and general properties. Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. The tautomer of HCN is HNC, hydrogen isocyanide. [citation needed] HCN has a faint bitter almond -like odor that some people are unable to detect owing to a recessive genetic trait. [13] The volatile compound has been used as ...
