Forensic Chemistry and Forensic Chemist Forensic chemistry is becoming an increasingly popular topic. It is being used quite often in the real world with police investigations‚ cases‚ and is also being magnified in television shows including Forensic Files‚ CSI‚ and Bones (What is Forensic Chemistry?). Forensic chemistry is important because without it we wouldn’t know the outcome of a crime. The forensic chemist’s job is to examine evidence given to them from a crime scene‚ when it happened‚ and

Background: Lipid and protein composition varies in tissue types. Results: When comparing liver‚ muscle‚ and adipose tissue‚ adipose tissue had the highest percent lipid and liver tissue had the highest percent protein. Conclusion: Based on analysis of the gels‚ the liver appeared to have the most variety in proteins when comparing liver‚ muscle‚ and adipose tissue. Significance: In order to determine the composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed

Title: Testing For Macromolecules Objective: Introduction Proteins are complex molecules which consists of carbon‚ oxygen‚ hydrogen and nitrogen. All proteins are made up of one or more polymers‚ known as polypeptides. Its monomers are amino acids. Protein can be divided into primary structure‚ secondary structure‚ tertiary structure and quaternary structure. It is important for all living things in the world as they form enzymes‚ antibodies and hormones. Materials and Procedures:

Investigating the Biomolecules found in Gelatin Abstract: For this inquiry lab‚ the research team tested the gelatin solution for the presence of biomolecules. The team searched for the presence of starch‚ glucose‚ lipids‚ and proteins through the use of indicators: Sudan III‚ Lugol’s iodine‚ Benedict’s solution‚ and Biuret’s reagent. After testing the gelatin solution in the presence of the indicators‚ the results showed that Lugol’s reacted‚ turning orange-pink (oils) and the Biuret reagent (protein)

Unit 1 Questions. Total: 16 marks 1. How many electrons does Mg2+ have? (1 mark) 10 electrons 2. Given that the half-life of the radioisotope carbon-14 is 5730 years‚ how useful do you think this isotope would be for dating bones that are over a million years old? (2 marks) 3. Summarize the four major types of biochemical reactions studied in this lesson. For each type give its name‚ a word summary of what happens during the reaction‚ and an example of where the reaction might be biologically important

Organic compounds are very important to a body. They are help the body to do things and replenish it. The 4 organic compounds I will talk about are carbohydrates‚ lipids‚ proteins and nucleic acids. I will explain what they do and what they are made of. Carbohydrates are in foods‚ some examples are sugars and starch. The structure of a carb is ring shaped‚ it is an easy one to know. The monomer of a carb is monosaccharide‚ which means one sugar. A monosaccharide consists of glucose‚ fructose and

Title: Determining which organic molecules are present in a series of unknown dietary supplements ● Introduction: Our main objective was to find out if the dietary supplements that claimed to be providing high levels of proteins contained fillers such as starch and sugar. We developed and carried out tests to determine which organic molecules were present in a series of unknown supplements. This is important because it is important to know what is in the food you eat for yourself and not always reply

Are you weak‚ tired‚ and lazy all the time? With macromolecules‚ your body will be bigger‚ better‚ faster‚ stronger‚ and built to last longer! There are four major macromolecules that can give you more energy‚ strength‚ and enough fat to keep you warm and protected. In conclusion‚ the four major macromolecules are important to growth and development because they produce and store energy‚ create muscle to build a repair the body‚ create fat when it gets cold‚ and to tell when to release amino acid

Aim: To verify the buffering capacity of a phosphate solution using a pH meter and construct a titration curve of an amino acid to determine the pka values of its ionisable groups to identitfy an unknown amino acid. Method: The ratio of [HPO42-] to [H2PO4-] required to produce buffer solutions at pH values 5.9‚ 6.9 and 7.9 were calculated. 0.1M of H2PO4- and 0.1M HPO42- were used to mix appropriate volumes to 25mL of each of the buffer solutions. The calibrated pH meter was used to measure
