The word "maltase" is a term that refers to an enzyme that breaks down maltose, a type of sugar. The correct spelling of this term is /ˈmɔːlteɪs/, with the stress on the second syllable. In IPA phonetic transcription, the first syllable is pronounced as "mɔːl", the second syllable as "tɛɪs", with a slight emphasis on the "tɛɪ" sound. The spelling reveals that the word is derived from the word "malt", with the "-ase" suffix indicating that it is an enzyme.
Maltase is an enzyme that plays a crucial role in the digestion of carbohydrates, specifically in the breakdown of maltose into glucose molecules. It is produced and secreted by cells lining the small intestine, where carbohydrate digestion primarily occurs.
Maltase belongs to the class of enzymes known as carbohydrases, which are responsible for breaking down complex carbohydrates into simpler sugars that can be easily absorbed by the body. More specifically, it is part of the glycoside hydrolase family 13.
The primary function of maltase is to catalyze the hydrolysis reaction, where a water molecule is added to the maltose substrate, resulting in the splitting of the molecule into two glucose molecules. This process is essential for the absorption and utilization of glucose by the body, as glucose is a vital source of energy.
Deficiencies in maltase production or malfunction can lead to a condition known as maltase deficiency or sucrase-isomaltase deficiency, where individuals experience digestive symptoms such as bloating, abdominal pain, and diarrhea after consuming foods containing maltose.
In addition to its role in digestion, maltase can also be used in various industrial processes, such as brewing and baking, to break down complex carbohydrates present in grains and produce sugars that are utilized by yeast or other microorganisms for fermentation.
Overall, maltase is an important enzyme that enables the breakdown of maltose into glucose, facilitating carbohydrate digestion and absorption for energy production and overall bodily functions.

The word "maltase" has its origins in the field of biochemistry. It is derived from the word "malt", which refers to a grain, typically barley, that has been germinated and then dried in the process known as malting. The suffix "-ase" in biochemistry indicates an enzyme, so "maltase" essentially means the enzyme that acts upon malt.
The term "maltase" was first introduced by the German physiologist C. O'Sullivan in 1903 when he discovered the enzyme that breaks down maltose (a disaccharide found in malt) into glucose. This enzyme was subsequently named "maltase" due to its specific action on maltose.
