Structural Biochemistry/Free energy - Standard Gibbs Free Energy of Formation. 1  When we have to consider the relationship between Gibbs free energy and the standard-state free energy of a reaction, we use this equation... 2  to calculate Gibbs free energy at that of time under a specific circumstances.
digestive system definition. The organs and glands in the body that are responsible for digestion.
