Galactose in dairy products
Galactose is used to study ageing in mice and rats One glass of milk contains equal amounts of galactose per body weight as those used in animal studies calculated as a split lactose molecule This raises the question of how much galactose different dairy products contain and provided that galactose is bad for us which products we should avoid |
What is the molecular formula of galactose?
Galactose is a monosaccharide sugar; the molecular formula of galactose sugar is C6H12O6. When a galactose molecule attaches to a glucose molecule, lactose is formed. It has a molecular mass of 180 g/mol. The density of this monosaccharide sugar is 1.2 g.cm3. Its main source in the diet is lactose which is found in milk and dairy products.
What is the difference between galactose and glucose?
Galactose shows resemblance with Glucose in every aspect except one. The only difference in galactose and glucose is the place of one hydroxyl group. However, this small structural difference gives different chemical and biochemical properties to the galactose when compared to glucose. Galactose exists in both cyclic and open-chain forms.
Who first isolated and studied galactose?
Galactose was first remoted and studied by Louis Pasteur in 1856 and he gave the name “lactose”. In 1860, Berthelot renamed it “galactose” or “glucose lactique”. In 1894, Emil Fischer and Robert Morrell determined the configuration of galactose. Galactose exists in both open-chain and cyclic forms.
What are the chemical and biochemical properties of galactose?
Galactose is a monosaccharide sugar whose chemical or molecular formula is C 6 H 12 O 6. This is a six-carbon sugar, which is an odourless white solid that has a sweet flavour. It is a reducing sugar and has a molar mass of 180.156 g/mol. It is water-soluble and slightly soluble in ethanol.
