Abstract:
D-Tagatose is a hexoketose monosaccharide sweetener, which is an isomer of D-galactose and is rarely found in nature. Recently, there has been industrial interest in D-tagatose as a low-calorie sugar-substituting sweetener. This article describes the properties and metabolism of tagatose as well as its commercial importance. The comparison between the biological tagatose production and the chemical production was reviewed based on the example of the glucose isomerization into fructose. The industrial problems facing its commercial application is described and evolving potential solutions are suggested.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
