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

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

Living things get energy to do things through photosynthesis‚ food molecule breakdown‚ build up‚ storage‚ and lastly cellular respiration. All of these ideas are the reason that myself and others have energy to do anything and everything. Photosynthesis is one way plants(plants are the main source of energy for all things)get energy to do things. The reactants of this are water‚ carbon dioxide‚ and although light energy is not a reactant‚ it is necessary once the energy from the seed is gone. Carbon

Proteins play an important role in the human body. The DNA molecule controls the synthesis of proteins. The DNA contains genes which are sequences of nucleotides and bases. Proteins are used for growth and repair. Proteins are made up of amino acids linked together by peptide bonds. Firstly ’amino acid synthesis ’ is the set of biochemical processes by which the various amino acids are produced from other compounds. The substrates for these processes are various compounds in the organism ’s diet

Refined sugar is unhealthy when consumed in large amounts and there are healthier options. Refined sugar has no nutrition. There are also many health risks when sugar is over consumed. Humans need carbohydrates to survive but there are many healthier way to get them than too many cookies or soda. Simple sugar is made of two components. They are mainly fructose and glucose(Dubost‚ June 12‚ 2013). Sugar is naturally produced in plants during photosynthesis. It is found naturally in milk‚ fruit‚

Purine metabolism is central to the production of nucleotides in the body. Imbalances in this process can lead to hyperuricemia which is abnormally high levels of uric acid in the blood [>360μmol/L in females and >400μmol/L in males]. Hyperuricemia can lead to uric acid crystals precipitating in the joints‚ skin‚ vessels and other tissues‚ this is a form of inflammatory arthritis known as gout. Uric acid is a metabolite of purine metabolism therefore gout can aptly be characterized as a disorder
