from more complex carbohydrates such as starch from corn‚ wheat‚ potatoes or cassava. Ethanol thus produced is expensive as it dips into food and feed material. Bioethanol refers to ethanol produced from complex carbohydrates such as lignocellulose which is not used as food or feed. It has been estimated that approximately half of the carbon fixed annually within terrestrial ecosystems is stored as lignocellulose; thus there is an abundant source of complex carbohydrate for bioethanol production

Title: Benedict ’s test for Reducing Sugars Testable Question: Are all carbohydrates reducing sugars? Hypothesis: If the carbohydrate contains available ketone or aldehyde molecules then they are reducing sugars. Variables: a. Independent: Function groups react w/ reagent b. Dependent: Color change (red‚ orange‚ yellow) Control: Water Materials: - 4 mL of each solution (Water‚ Starch‚ Glucose‚ Maltose‚ Sucrose‚ Onion Juice‚ Potato slice‚ Milk) - 8 test tubes

to these substances to give them a better taste. 6. Which food substances contained starch? Are these results expected? Explain. The potato contained starch. This was expected because I know a medium sized potato can contain up to 30 grams of carbohydrates. 7. Which substances contained protein? Are these results expected or not? Explain. The chicken and the eggs contained protein. This was expected

There is a huge difference between no carb diets and low carb diets. The no carb diet is where there is total elimination of all carbohydrates in everyday meals. This means that the person has to rely on fats from animal source foods as the main source of energy. This diet is particularly well suited for people who need to go on ketogenic diets‚ particularly a small number of epileptic children with difficult-to-cure conditions. People often mistake this kind of diet with the low carb diets. It should

Examples of good protein sources for dancers are tofu‚ beans and meat. The benefit of carbohydrates is to provide energy production to the body. The muscles are stored with glycogen through the

human body needs a certain amount of nutrients for proper functioning and in order to maintain a healthy weight. The diet holds some key essential guidelines that will allow for optimal body performance. These include: High protein intake‚ Low carbohydrate intake (less than 15% of diet)‚ Drinking a gallon of water per day‚ low salt consumption‚ and Low complex sugar intake.

bar sit still on the shelf in the grocery store? Indeed‚ candy bars have a significant amount of carbohydrates (mostly simple‚ such as sugar) in their composition. The energy stored within these carbohydrates is chemical potential energy‚ and cannot actually be released or converted into usable chemical energy until it is eaten and taken up into the body‚ where various cells break down the carbohydrate molecules and contribute to the body’s metabolism via the different pathways (e.g.‚ citric acid
