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.
In general, galactose does not occur in the free state but is a constituent with glucose of the disaccharide lactose or milk sugar. It is less sweet than glucose. It is a component of the antigens found on the surface of red blood cells that determine blood groups.altose is formed during the germination of certain grains, the most notable being barley, which is converted into malt, the source of the sugar's name. A molecule of maltose is formed by the combination of two molecules of glucose.
