- Glycolysis Broken Down
Glycolysis can be a pretty daunting concept to really get a firm understanding on, with so many different molecule derivatives involved. So here, I will be explaining this process in a step-by-step manner that hopefully, will help alleviate any frustrations....

Coined/History
The isomerism was first noticed in 1827, when Friedrich Woehler prepared cyanic acid and noted that although its elemental composition was identical to fulminic acid its properties were different. The term ?isomerism? coined in 1830, by Swedish chemist Jons Jacob Berzelius(1779-1848) who wrote ?those bodies that have the same composition but different properties?. Louis Pasteur (1822-1895) in 1848 separated racemic acid into its two optically active tartaric acid components by crystallization. The first documented occurrence of isomerase was shown by Meyerhof and Kiessling (1935) for reaction: Glyceraldehyde phosphate to dihydroxyacetone phosphate.

Definition
Isomerases are the enzymes that catalyze the structural rearrangement of isomers (molecules with mirror-image relation) such as isomerase that converts L-alanine to D-alanine or the Glucose-6-phosphate isomerase that converts glucose-6-phosphate in the second step of glycolysis. They have the EC classification as EC 5.
