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.
Lactose and galactose are both carbohydrates -- more specifically, they're sugars. Galactose is actually a chemical component of lactose, and lactose is milk sugar that you take in whenever you consume dairy.actose is a disaccharide, meaning it's made up of two smaller monosaccharide units. Specifically, lactose consists of a glucose chemically bonded to a galactose, giving it the overall chemical formula C12H22O11.
