This sugar is called sucrose. Sucrose is a combination of glucose and fructose. Glucose and fructose combine to make sucrose in a dehydration synthesis reaction. Sugar, or sucrose, is used as an energy source by humans. Sucrose is used to sweeten foods, and provide short term energy.
Energy is released when glucose is broken down into carbon dioxide and water. Lipids are compounds that are insoluble in water and soluble in solvents. Lipids include fats, oils, phospholipids, steroids, and
This amylase converts the remaining starch into maltose. Maltose and lactose are absorbed into the small intestine. Multiple enzymes reside in the microvilli that lines the small intestine: maltase, lactase and sucrose. They’re called brush border enzymes The brush border enzymes convert the disaccharides into monosaccharides: glucose, fructose, and galactose. The monosaccharides are them absorbed into the bloodstream.
Mixed Solutions: If 1 mmole of glucose (180mg=1mOsm) and 1 mmole of NaCl (58mg=2mmOsm) are put into a beaker and distilled water added to make 1 liter, the osmolarity is 3 mOSm/L. OSMOSIS CALCULATIONS: 1. Calculate the number of grams of NaCl needed to prepare 100 mL of a 280mOsm.L Solution. (280mosm/l) *(1L/1000mL)*(100mm/1)*(29mg/1mosm)*(1g/1000mg)=0.812g 2. Calculate the number of grams of glucose needed to prepare 100mL of a 280 msm/L glucose solution.
Exploring enzymes through Lactex. Problem: Does pH affect the results of Lactex? Independent Variable: pH value Dependent Variable: Glucose Control: Lactex enzyme Hypothesis: I think pH will cause the result of Lactex to change. Materials: · Soap (basic) · Antacid (basic) · Soda (acidic) · Vinegar (acidic) · pH test strips · eye dropper · Cow’s milk Experimental Design: 1. Set up plastic cups 2.
Lactase Buffer solutions 4,7,9 Enzymes are organic catalysts that control the rate of chemical reactions in cells while not being permanently altered themselves. In general, enzymes speed up the rate of reaction by lowering the activation energy required to start reactions. Lactase is an enzyme used by the body to hydrolyze lactose, a disaccharide unique to mammalian milk, into the monosaccharaides, glucose and galactose. Lactose has been shown to aid in the absorption of several minerals, including calcium, magnesium, and zinc. .
3. 4. Increasing the concentration of a solution will __________ the boiling point of the solution Increasing the concentration of a solution will __________ the freezing point of the solution Procedure: (BE SURE TO RECORD ANY OBSERVATIONS!) 1. Measure 1/2 cup (c) milk and 1/2 c whipping cream; put into a small Zip-lock baggie.
The specific substrate in this case that is acted by Aldolase B is fructose-1-phosphate. This is later converted into DHAP and glyceraldehyde. The product, once finished, will then enter the glycolysis cycle to form ATP (Hudon-Miller, 2012c). Role of Aldolase B in the Breakdown of Fructose Aldolase B is found mostly in the liver but can also be present at lower levels in the kidney and intestinal cells. It is involved in breaking down a simple sugar called fructose.
Glucose travels in the plasma or liquid part of your blood but cholesterol (triglycerides) travel bound to protein carriers in the blood. Based on their respective chemical properties, explain the reason for this difference. (2 marks) Cholesterol is an amphipathic molecule, since it has polar and non – polar regions. Even though the cholesterol has polar group (OH) it dissolves fats than in aqueous
Secretes pancreatic juice, insulin, glucagon, duodenum, and somatostatin into the bloodstream. Regulates blood sugar and completes the breakdown of protein, carbohydrates and fats 17. Responsible for the production and maintenance of the protective mucous blanket by synthesizing and secreting glycoproteins known as mucins. 18. Stores and concentrates bile 19.
