Document Summary

Carbohydrates are one of the three macronutrients. The referred energy source for nerve cells and the brain. Obtained mostly from plant foods (fruits, veggies and grains) Plants make most abundant form of carbs > glucose through photosynthesis, founds in disaccharides and complex carbs. Carbs can be classi ed as simple or complex (terms used to classify carbs based on the number of sugar molecules present) Simple: one or two molecules (monosaccharides and disaccharides) Glucose: most abundant sugar molecule in our diet, good energy source. Fructose: sweetest natural sugar, found in fruit, high fructose corn syrup. Galactose: does not occur alone in foods; binds with glucose to form lactose. Each of those monosaccharides contain 6 carbon, 12 hydrogen, and 6 oxygen. Ribose: another monosaccharide, 5 carbons, located in the genetic material of our cells. Lactose: consists of one glucose molecule and galactose molecule. Maltose: consists of two molecules of glucose.

Charts and tables are tools we use in science to break down information analytically and present data in an organized manner. It is a beneficial strategy for learning about and organizing scientific material, which we will be using often in this class. Make sure that you are detailed, thorough, and specific in your responses. Explain yourself clearly. Do not list a word or brief phrase without explaining what it means. For example, if you list diabetes for carbohydrates, make sure you explain how carbs are associated with diabetes. Don't leave the reader to make that connection for you. Also, make sure you provide APA-style references for each of your so
