Sucrose is the most commonly used sugar in the food industry. This sugar is a staple 15 food product and as such plays a major role in our diet; Sucrose is used as an industrial sweetener in baking, drinks, confectionary, jams, jellies, preserves etc. Sucrose is als6 used in the home as normal table sugar for sweetening tea, coffee, desserts, etc.

The main source of carbohydrate in these diets was sucrose and the primary source of fat was lard. TestDiet ® (Richmond, IN, USA) created the TestDiet ® 21st Century Western Diet™ Series. This consists of a low-fat control (5TJS: 12% kcal from fat), a medium fat (5TJN: 40% kcal from fat) and a high-fat diet (5TJP: 56% kcal from fat).

Neurospora cells grown in the presence of sucrose have a very low capacity to utilize acetate as a carbon and energy source. However, after a shift to an acetate- containing medium, they start to form glyoxysomes and the enzymes of the glyoxylate cycle which enables them to grow well on acetate [17-231. The sucrose-

Sucrose is the predominant form of sugar transported from photosynthetic (source) to non-photosynthetic (sink) organs in higher plants relying on the transporting function of sucrose transporters (SUTs or SUCs). Many SUTs have been identified and characterized in both monocots and dicots. However, t …
