Activation energy — In chemistry, activation energy, also called midnight energy, is a term introduced in 1889 by the Swedish scientist Svante Arrhenius, that is defined as the energy that must be overcome in order for a chemical reaction to occur. Arrhenius… … Wikipedia
Carbon-hydrogen bond — A carbon hydrogen bond, also known as a C H bond is a single bond between carbon and hydrogen atoms, most commonly found in organic compounds [JerryMarch] . Carbon hydrogen bonds have a bond length of 1.09 Å (1.09 × 10 10 m) and a bond energy of… … Wikipedia
Peptide bond — A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, thereby releasing a molecule of water (H2O). This is a dehydration synthesis reaction(also… … Wikipedia
