of beet juice | Bluish-Black | Analysis: * From the experiment it was obvious that the starch solution was the positive control‚ while the distilled water was the negative control. * It was concluded that the iodine reacted to coiled carbohydrates. Conclusion: * At the end of this experiment I was able to conform and accept my hypothesis‚ since the positive control; starch‚ and the other rich in starch solutions turned to Bluish-Black

AS Biology‚ Biological Molecules Revision Notes Distinguish between monomers and polymers: Monomers- Identical small molecules. Polymers- Chainlike molecules formed from the linking together of many similar. Distinguish between monosaccharides‚ disaccharides‚ and polysaccharides: Monosaccharides- Simple sugars; sugar molecules may be enantiomers due due to the spatial arrangement of parts around asymmetric carbons; raw material for synthesis of other organic molecules. Disaccharides-

In fact‚ they are “almost polar opposites of each other”(4). The Mediterranean diet consists of fruits and vegetables‚ good oils and chicken and fish (4). The American diet however‚ is high in carbohydrates‚ sugars‚ bad oils‚ and red meats (4). Unlike the Mediterranean diet‚ the standard American diet does not put an emphasis on fruits and vegetables (4). American diet consists heavily of processed foods‚ fried and fast foods‚ red meats and bad oils

Getting Lean With Carb Cutter? Many Americans have turned to diet pills. Should you? In the United States today many people have supposedly lost weight with certain pills. One of these pills is called carb cutter. Carb Cutter claims to inhibit the activity of the starch-digesting enzyme‚ amylase. When the diet pill binds to the amylase‚ it prevents the breakdown of starch. In the Biology 1103 lab‚ we conducted two experiments to determine whether or not the diet pill‚ Carb

with discretion; opt for carbohydrates with a low glycemic index (GI). GI is the property of a carbohydrate to be converted into blood sugar. A low GI indicates that a carbohydrate takes longer to be converted to sugar‚ thus implying that it is contains insoluble fiber that is tougher to break down (that’s good news‚ intestines need some exercise too). While consuming carbohydrates‚ watch out for the glycemic load (GL) too. Glycemic load accounts for how much carbohydrate is in the food‚ and how much

The structure and function of carbohydrates A carbohydrate is an organic molecule containing only Carbon‚ Hydrogen and Oxygen with the general formula Cn(H20)n. They are made up of individual molecules called monomers which are joined together by condensation reactions to make a longer chain called a polymer. Carbohydrates are categorised in to three main groups; monosaccharides‚ disaccharides and polysaccharides. Monosaccharides are single sugars and are sweet tasting soluble substances such

Dr. David B. Samadi said that‚ “Many diabetics find that products with artificial sweeteners help curb cravings as sweeteners tend to be much more intense than regular sugars and having no carbohydrate or effect on blood glucose levels.” This is a plus for diabetics to have artificial sweeteners since most like to consume lots of sweeties. “It enables people that are carb‚ sugar or calorie conscious to take in a wider range of foods that they

Two other major biomolecules that were not tested in the lab were Nucleic Acids and Carbohydrates. If we study the foods before the lab we can observe what biomolecules may be in the foods. Since Turkey Gravy contains meat‚ it may contain Protein. Since Applesauce comes from an apple‚ it should contain some sort of natural sugar. Biomolecules

Milk is a very important source of nutrition for humans of all ages‚ infants and senior citizens alike. It is a major source of proteins and carbohydrates and also a variety of vitamins and ions2. Milk is processed into a variety of dairy products such as butter‚ cream‚ yogurt‚ cheese and ice cream3.

There are four types of macromolecules: carbohydrates‚ proteins‚ lipids and nucleic acids. In this lab we will test four foods to see if they contain carbohydrates (sugar and/or starches)‚ proteins and lipids. We will use chemical reagents to test to determine the presence of macromolecules: Benidicts solution for sugar‚ Iodine for starch‚ Biurets reagent
