Milk it not only does the body good but increased my knowledge! 1. I ate/drank milk. The macromolecular level of milk is carbohydrate‚ fat‚ and protein. Protein is called a casein which is di –is the lactose‚ Carbohydrate is Mono- is the glucose (simple sugar)‚ Fat is a straight chain fatty acids that are saturated and is poly – I think. 2. The monomer for the protein is amino acid – milk has all 9-essential amino acids. The monomer for the carbohydrate is monosaccharide‚ which is a simple sugar

by the empirical formula of Cm(H2O)n and has a hydrogen to oxygen ratio of 2:1. There are three types of carbohydrates‚ the first being monosaccharides‚ which are simple sugars such as fructose and glucose. One of their main purposes is to act as an energy source for plants and animals; such as glucose being broken down during cell respiration. Monosaccharides are also monomers which serve as building blocks for more complex carbohydrates to form. Disaccharides is the second group and consists of
Premium Glucose Carbohydrate Sucrose
Carbohydrates can be broken down into monosaccharides which is a single sugar unit that can be glucose‚ fructose and galactose. This is called catabolism. Disaccharides are 2 sugar units linked together such as condensation‚ lactose‚ sucrose or maltose. Condensation allows to from water. Polysaccharides are multi-sugars. This can provide starch by glyosidic bonds. Another is glycogen. This product is stored as glucose which is reserved in the liver and muscle. Carbohydrates

1. Prepare a lactase enzyme solution by dissolving one lactase enzyme tablet in 200 ml of water in a clean 250 ml beaker. Stir until the tablet has dissolved. Use labeling tape to label the beaker: “Lactase Enzyme Solution.” 2. Prepare a “denatured” enzyme solution by pouring 20 ml of your enzyme solution into a heat resistant tube. The test tube must have the words “Kimax” or “Pyrex” on it. If it does not‚ it is not heat resistant and may break! Use labeling tape to label the test tube: “Denatured

the milk easier for people with lactose intolerance to digest. Glucose – ethanol+carbon dioxide (+energy released) It lets organisms live in places where there is little or no oxygen. Such places include deep water‚ soil‚ and the digestive tracts of animals such as humans. Plants If the roots of a plant get waterlogged they start to run out of oxygen too. So they need to use a different form of anaerobic respiration. glucose → ethanol + carbon dioxide (+ energy released) When no oxygen

Sugar To add Benedict’s reagent to four substances‚ glucose‚ starch‚ onion juice‚ and distilled water‚ to test the detection of sugar in each. Test Sample Predicted Results Benedict’s Results 1. Glucose Change in color Color changed to a dark red 2. Starch Change in color Color changed to a dark red 3. Onion Juice Change in color Color changed to a dark red 4. Distilled Water No change No change in color The test tube with the Glucose‚ Starch‚ and onion juice were the positive controls

Let’s start. • Nutrition is a study of the interactions occurring between you & food. • Nutrients – about 45 substances that provide energy‚ structure or regulation of body processes. • Essential nutrients- need them‚ but can’t make them or fast enough. • Macronutrients- need in large amounts (carbohydrates‚ fats/lipids‚ proteins – provide energy/calories) • Micronutrients – need in very small amounts (vitamins‚ minerals- no energy/calories) • Phytochemicals- another category in plant food-

1. The properties of water are essential to all life on Earth. a. Outline the significance of the labeled parts of this diagram‚ showing the attraction between three water molecules. | w. | Negative charge oxygen atom | | x. | Positive charged oxygen atom | | y. | Weak hydrogen bond between δ+ and δ- parts of neighboring water molecules. | | z. | Strong hydrogen bond | | δ- | Slight negative charge as large oxygen atom attracts shared electrons closer to itself than the hydrogen

our food supply includes addition of fructose‚ removal of fiber‚ and substitution of trans-fats. Thirdly‚ Dr.Lustig explains the differences between fructose and glucose. He says that a calorie is not a calorie‚ and fructose is not glucose; it’s more likely to form AGE’s‚ doesn’t suppress ghrelin and stimulate insulin. Glucose can be used by any cells in our body and any living things on the surface of Earth. It can produce energy of life and VLDL‚ which can cause obesity and heart diseases
