Reducing class size gained prominence as a federally supported school-improvement strategy in 2000, with the creation of a federal class-size-reduction program, which gave states funding to recruit, hire, and train new teachers.
Simple carbohydrates have one (single) or two (double) sugars. Complex carbohydrates have three or more sugars.â Examples of simple carbs include fructose (fruit sugar), lactose (milk sugar) and sucrose (table sugar). Complex carbs, sometimes called starches, include legumes, potatoes, rice and grain products. Note that the simple/complex distinction is completely arbitrary. At molecule 3 in the chain of sugars we simply start calling it complex.
What makes one carbohydrate different from another is the number of sugar units it contains and how the units are linked together. 1  Simple carbohydrates: These carbohydrates have only one or two units of sugar. A carbohydrate with one unit of sugar is called a simple sugar or a monosaccharide (mono = one; saccharide = sugar). Fructose (fruit sugar) is a monosaccharide, and so are glucose (blood sugar), the sugar produced when you digest carbohydrates, and galactose, the sugar derived from digesting lactose (milk sugar). A carbohydrate with two units of sugar is called a double sugar or a disaccharide (di = two). Sucrose (table sugar), which is made of one unit of fructose and one unit of glucose, is a disaccharide. Complex carbohydrates: Also known as polysaccharides (poly = many), these carbs have more than two units of sugar linked together.
