Is the ethylene gas that is used to ripen tomatoes quickly in supermarkets safe? Ethylene gas is produced naturally by most fruits, such as tomatoes, bananas, peaches, and avocados, and it promotes ripening. Most tomatoes today are picked green and transported unripe to protect them from bruising and spoilage.
Galactose (galacto- + -ose, milk sugar), sometimes abbreviated Gal, is a monosaccharide sugar that is less sweet than glucose and fructose.It is a C-4 epimer of glucose. Galactan is a polymer of the sugar galactose found in hemicellulose.Galactan can be converted to galactose by hydrolysis.alactose is a monosaccharide. When combined with glucose (monosaccharide), through a condensation reaction, the result is the disaccharide lactose. The hydrolysis of lactose to glucose and galactose is catalyzed by the enzymes lactase and Î²-galactosidase.
Galactosemia is a disorder that affects how the body processes a simple sugar called galactose. A small amount of galactose is present in many foods. It is primarily part of a larger sugar called lactose, which is found in all dairy products and many baby formulas.The signs and symptoms of galactosemia result from an inability to use galactose to produce energy. Researchers have identified several types of galactosemia.These conditions are each caused by mutations in a particular gene and affect different enzymes involved in breaking down galactose. Classic galactosemia, also known as type I, is the most common and most severe form of the condition.If infants with classic galactosemia are not treated promptly with a low-galactose diet, life-threatening complications appear within a few days after birth.t is primarily part of a larger sugar called lactose, which is found in all dairy products and many baby formulas. The signs and symptoms of galactosemia result from an inability to use galactose to produce energy. Researchers have identified several types of galactosemia.
