Biological Macromolecules Lab Cells‚ the fundamental units of life‚ are composed of various combinations of organic macromolecules: carbohydrates‚ lipids‚ proteins‚ and nucleic acids. This lab exercise is designed to show you the qualitative tests commonly used to detect their presence. Objectives Test for the presence of monosaccharides by using the Benedict’s test Test for the presence of starch‚ a polysaccharide‚ by using the Lugol’s iodine test Test for the presence of lipids by using the

Definitions Alpha glucose- is an isomer. The hydroxyl group is attached facing down and away from the main structure. Beta glucose- is an isomer except the hydroxyl group is attached above the ring and on the first carbon. Fructose- a sugar of the hexose class‚ and is a simple ketonic monosaccharide found in many plants‚ where it is often bonded to glucose to form the disaccharide sucrose. Sucrose- Sucrose is a sugar‚ the organic compound commonly known as table sugar‚ cane sugar‚ beet sugar or

Diabetic people are advised to avoid sugary merchandise as a result of they will trigger the blood sugar ranges to surge up. That is dangerous within the brief term as a result of the particular person may feel unwell and have to make use of insulin substitute therapy to reduce the blood sugar. It is unhealthy in the long run because blood sugar control is vital in preventing further diabetic problems‚ like neuropathy‚ retinopathy and cardiovascular diseases. However this poses an issue for a diabetic

The experiment was to examine the blood glucose concentrations over a period of time after the intake of carbohydrate (coke) compared with a controlled test (intake of diet coke that has no sugar content). b) Coke contains sugar‚ a type of carbohydrate‚ which will be absorbed by the liver from the gastrointestinal tract after being digested into monosaccharides‚ mainly in the form of glucose‚ into the bloodstream. The body will

An example would be I am watching my saturated fat intake and carbohydrates. I have an 18 ounce jar of Jif Omega-3 peanut butter. There are 15 servings in a jar. A single serving of peanut butter is two tablespoons. The saturated fat for this particular item is 14% of the recommended daily requirement. The total fat for

Veronica Guerrero Macromolecules of Life The macromolecules of life experiment involves the biology of life. The biology of life includes carbohydrates‚ lipids‚ proteins and which will not be included in this experiment nucleic acids. The introduction of this experiment will reference how to become familiar with lipids‚ carbohydrates‚ and proteins. It will also include the knowledge of how these macromolecules function in living organisms. This experiment will identify the macromolecules

and how it deals with our daily classroom requirements. Our brain needs several very important ingredients to make it more efficient with our academic success. Shockingly‚ fats are critical‚ our brains need good fats. We also need proteins‚ carbohydrates and water. These ingredients are really necessary for us to process information effectively. We will now look at the way our brains work. Within your brain‚ a biochemical process of learning is occurring‚ that parallels the classroom experience

Since hypoglycemia is the most adverse effect‚ it could be life threatening‚ so you want to make sure theYL has emergency sugar supply with her at all times. Ex.
