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.
The structure of Galactose monosaccharide sugar is a normal chain of six carbon atoms. It is an isomer of Glucose and Fructose. Below is a structure of Galactose in open chain form: H-C=O. |. H-C-OH. |. OH-C-H. |. OH-C-H.-C-OH. |. OH. To understand the pyranose ring form of Galactose, draw a hexagon, assume the joints as carbon atoms except one joint-that is an oxygen atom. Let the joints be A, B, C, D, E, F. To the joints A, C, D, E, F, assume them to be carbon atoms, and the joint B to be oxygen atom.
Galactosemia is an inherited defect of galactose metabolism caused by an enzyme deficiency that prevents proper metabolism and utilization of galactose, or milk sugar. The main dietary source of galactose is lactose, the principle carbohydrate found in all forms of milk.alactosemia is an inherited defect of galactose metabolism caused by an enzyme deficiency that prevents proper metabolism and utilization of galactose, or milk sugar.
