Half Life Experiment My hypothesis would be that after each shaking about half of the remaining candies would be logo-up and half of them logo-down. That’s why the shaking represents a "half-life". half-life || total time (sec) || # of undecayed atoms || # of decayed atoms 0 0 100 0 1 5 65 35 2 10 51

IDENTIFICATION OF SOME MACROMOLECULES | | INTRODUCTION Dehydration-synthesis is a reaction that occurs to form different types of macromolecules. It is a reaction that leaves a macromolecule structure along the lines of developing its own specific function in a living organism. The 4 most common ones are carbohydrates which includes monosaccharides and polysaccharides‚ lipids‚ proteins and nucleic acids (Mack 2012). Scientists identify different types of macromolecules to achieve a better

The compounds above in #2 have the same chemical formula but differ in ARRANGEMENT OF THE ATOMS. IDENTICAL MOLECULAR FORMULA BUT DIFFERENT STRUCTURAL FORMULA. 4. Starch and cellulose are examples of SUGARS 5. Sucrose‚ maltose‚ and lactose are of DISACCHARIDES (DOUBLE-SUGARS) 6. Chemical reactions that link two or more

Macromolecules BCM261/BCM262 Anonymous Student #2 Aim The purpose of this lab was to use the scientific method to identify an unknown solution‚ based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of micromolecule reacted with at least one indicator solution in a unique way‚ which allowed us to identify the macromolecule based upon the presence or

Test for the Presence of Macromolecules Introduction In this experiment‚ we are trying to identify the presence of macromolecules in certain solutions. As in our daily lives‚ macromolecules are the essential nutrients that we have to take every day‚ therefore we would like to identify the types of macromolecules that contain in some of the food or solution in order to maintain a healthy life. There are four groups of macromolecules which are carbohydrates‚ lipids‚ proteins and

Monosaccharides ▪ Simple sugars o Disaccharides ▪ Compound sugars o Polysaccharides ▪ Complex sugars a. Monosaccharides • Simple sugars • Contain about 3 to 6 carbon atoms per molecule o Trioses ▪ The three carbon simple sugars o Pentoses ▪ The five carbon simple sugars ▪ Examples are – Ribose and Deoxyribose

In the sandwich you just ate‚ you have consumed three raw macromolecules. The bread would be considered the carbohydrate. The mayonnaise is the lipid. The turkey is of course considered the protein. Although the body takes in these three different forms one way‚ the way the body breaks it down is in three ways. First is the break-down of the carbohydrates(bread). The polysaccharide form of this is too big for the body to simply break down directly. So‚ instead the body uses multiple forms of procedures

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

Biuret test. Introduction The purpose of this experiment was to identify the presence of macromolecules by using various positive and negative controls. The principle building blocks of living organisms are essentially constructed by carbon-containing molecules in cells. (Alberts‚ 2009) The macromolecules including lipids‚ carbohydrates‚ proteins‚ and nucleic acids contribute to the most distinctive properties on living organisms. Macromolecules are known as polymers which are constructed by small
