Anselme Payen (French:; 6 January 1795 – 12 May 1871) was a French chemist known for discovering the enzyme diastase, and the carbohydrate cellulose. Biography ...
His work on diastase, also known as amylase, was carried out in collaboration with Anselme Payen and published in 1833. [3] His work on dextrin was carried out in collaboration with J.B. Biot [4] Persoz died in Paris on 12 or 18 September 1868. [1]
A diastase (/ ˈ d aɪ ə s t eɪ z /; from Greek διάστασις, "separation") is any one of a group of enzymes that catalyses the breakdown of starch into maltose.For example, the diastase α-amylase degrades starch to a mixture of the disaccharide maltose; the trisaccharide maltotriose, which contains three α (1-4)-linked glucose residues; and oligosaccharides, known as dextrins, that ...
The modern history of enzymes began in 1833, when French chemists Anselme Payen and Jean-François Persoz isolated an amylase complex from germinating barley and named it "diastase". [ 16 ] [ 17 ] It is from this term that all subsequent enzyme names tend to end in the suffix -ase.
Some argued that the beginning of biochemistry may have been the discovery of the first enzyme, diastase (today called amylase), in 1833 by Anselme Payen, [2] while others considered Eduard Buchner's first demonstration of a complex biochemical process alcoholic fermentation in cell-free extracts to be the birth of biochemistry.
Some argued that the beginning of biochemistry may have been the discovery of the first enzyme, diastase (now called amylase), in 1833 by Anselme Payen, [11] while others considered Eduard Buchner's first demonstration of a complex biochemical process alcoholic fermentation in cell-free extracts in 1897 to be the birth of biochemistry.
"The modern history of enzymes dates back to 1833 when, in the journal Annales de Chemie et de Physique, the French chemists Anselme Payen and Jean-Franois Persoz described the isolation of an amylase complex from germinating barley and named it diastase."
In 1833 French chemist Anselme Payen was the first to discover an enzyme, diastase. In 1834, François Mothes and Joseph Dublanc created a method to produce a single-piece gelatin capsule that was sealed with a drop of gelatin solution. In 1853 Alexander Wood was the first physician that used hypodermic needle to dispense drugs via Injections.
