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 (Galactosaemia) is a rare genetic metabolic disorder that affects an individual's ability to metabolize the sugar galactose properly. Galactosemia is not related to and should not be confused with lactose intolerance. Galactosemia follows an autosomal recessive mode of inheritance that confers a deficiency in an enzyme responsible for adequate galactose degradation. Goppert first described the disease in 1917, with its cause as a defect in galactose metabolism being identified by a group led by Herman Kalckar in 1956.
