Title:
Identification of the Main Groups in Macromolecules- Carbohydrates
Objective:
To investigate and identify the different types of carbohydrates

Background:
Macromolecules are large molecules that are present in our body. There are four main types of macromolecules, namely carbohydrates, lipids, proteins, and nucleic acids. Each one of them plays specific and significant roles in our body and each one of them is extremely important. If we are lacking either one of them, our body would receive the consequences.
Carbohydrates are one of the most essential sources of energy for our body. They a composed of the three elements, carbon (C), hydrogen (H) oxygen (O), and in the ratio of 1:2:1. With the general formula Cn(H2O)n. There are three common groups under carbohydrates, which are monosaccharide (simple sugar), oligosaccharides and polysaccharides. All of these groups possess different carbon structural and function between one another. There are many types of experiments that can be conducted to identify and differentiate the group from each other. Thus, the alb activity can surely help to further understanding between the relationship of the groups’ structure and their function.

...Lab #1 “Who has the same solid that I have?” Abstract Different Physical and chemical tests were performed on 10 numbered unknown solids and the results of all tests were compared as a class to try and determine which groups had the same unknown solids based on similarities in properties. It was found that my given unknown solid #11 shared similar properties with the unknown solid #1. A side by side analysis of the reactivity test in which Hydrochloric acid (HCI), lead nitrate (Pb(NO3)2) and sodium hydroxide (NaOH) was added to three separate samples of the compounds unknown #1 and #11 aqueous solutions. The results for both unknowns were identical, leading to the conclusion that my unknown solid #11 was the same unknown solid as #1. Introduction When conducting research it is important to be comfortable communicating your results with other researchers so that they can be further analyzed and compared with the results of other research experiments. Another large part of conducting research is to be comfortable determining, describing and comparing chemical and physical properties of compounds. Many compounds can look very similar, but have drastically different chemical properties, so it is important to know which tests can be performed on a compound to help determine what it is, or what it is not. In this experiment 2 sets of six unknown solid compounds were put into small jars and labeled with the numbers 1-12, numbers 4, 6 and 8 were not used. Each lab group was given...

...Abstract Species diversity in Guam’s limestone forests is extremely limited. In order to account the number of species available in comparison to the Panama tropical rainforests, data gathered from of 20x20 plots were recorded. Throughout this study, factors for Guam’s limited species diversity may be generalized but not fully confirmed. Overall the main purpose is to get an idea of what type of species are available in the limestone forests, as well as provide data for researchers to pursue further studies as to why species are so limited here on this island. Introduction Tropical rainforests, along with temperate ones, are the most complex biomes on earth. This is due to the many ecosystems found within them. Although it is assumed that rainforest are fertile with plant species due to nutrient-rich soil, it is not. Most nutrients are either washed away from the soil due to heavy rainfall or recycled through the vegetation. Usually new growth within the forest greatly depends on decomposing organisms, such as bacteria and fungi (Tang et al.2011). Specie diversity varies within these rainforests depending on conditions surrounding and affecting each. Considering that species diversity is one of many crucial elements to nature conservation, thorough studies must be conducted to identify such conditions of limited rainforests. (Primack 1993). Categorized within Tropical forests are karst or limestone forests that consist of endemic plants and trees. Guam’s limestone...

EQUIPMENT: Three different geometric solids: 1 identified as white cylinder, 1 identified as brass-colored cylinder, 1 identified as silver-colored sphere. Meter stick (wooden, displaying measurements in cm) Analog scale (zero-ed prior to experiment) Manual caliper Digital caliper (zero-ed prior to each measurement) PRINCIPLE: This lab is intended to reinforce the importance of using proper techniques to attain precise measurements. It further demonstrates that reliability of results from different measuring devices. In this experiment, the most rudimentary measuring tool was the meter stick followed by the manual caliper and then the digital caliper. Measuring each object five times should reinforce the different interpretations of team members as well as the variance between the different tools used to measure the objects. In addition to measuring the length, width and height of each object, the mass was attained through the use of an analog scale. While a digital scale would have shown a more precise measurement, the analog scale was a more appropriate tool with the meter stick and manual caliper as the significant figures produced by each ...

...Figure 10 shows both frequencies superimposed together. It is observed that when one frequency is low, the other remains high. In other words, only one tone is generated at any point in time. With these simulations, it can be inferred that the Ltspice results were as expected. Since these results align to what is known in theory, it is considered to be accurate. The prototype is only then built and tested with an oscilloscope. The results is recorded and shown in the figures below. 4.2 Oscilloscope Readings Figure 11: Oscilloscope Waveform for A1 Figure 11 shows the square wave produced from A1. The frequency obtained was 1.14Hz. Figure 12: Oscilloscope Waveform for A2 Figure 12 above shows A2 producing a frequency of 440.51Hz. Figure 13: Oscilloscope Waveform for A3 Figure 11 shows A3 producing a frequency of 1.4439kHz. Figure 14: Oscilloscope Waveform for both frequencies The results obtained from the oscilloscope measurements were relatively accurate. This can be seen by the two distinct waveforms occurring at separate times. Since these measurements tally with the Ltspice simulations, it clearly shows that the prototype is fully functional. The slight difference in the frequency values could have been attributed from several factors. Simulations produce frequency values under perfect conditions. On the other hand, the practical approach is faced with imperfections such as noise, internal resistance from components and experimental inaccuracies...
