In this lab, we will use simple indicators to test for the presence of organic molecules. This will be done by using different compounds, indicator solutions. These indicator solutions include Benedict’s solution, Biuret’s solution, Ninhydrin, Iodine, and Amylase. Benedict’s solution is used to detect the presence of sugars, whether they are a monosaccharide or disaccharide. The resting substance is a blue color until it reacts, turning either a yellow, orange, red, or green color, indicating it’s

I chose this element because it’s very expensive and I wanted to know what makes it so expensive. Since its more expensive than Gold and I thought Gold was more expensive than any element. Also because I want to know why people say “an artist just went Platinum.” Platinum was discovered in 1735 by Julius Scaliger. The spanish term is Platina which means “little silver.” The atomic number for Platinum is 78. Platinum has 78 Protons, 117 Neutrons, and 78 Electrons. The atomic mass for this element

Introduction Although nutrient transfer from host to parasitic mistletoe has been thoroughly quantified, were these nutrients go afterward and the consequences of this parasitic relationship on the ecology of the ecosystem remains poorly known. Indeed, it has been suggested that parasitism alters nutrient cycling since nutrients from the host accumulate in the parasite’s tissues and remain concentrated following abscission. Moreover, mistletoe has a higher leaf turnover than its host, which results

Enzymes: Clinical Applications Enzymes mediate almost every single biochemical reaction, process or metabolic event in the body. Overall, enzymes are proteins whose primary function is to catalyze, increase the rate of the biochemical reactions (Champe et al., 2005). Enzymes are not only efficient in increasing the rate or velocity in a biological reaction, but also are incredibly accurate at recognizing other biochemical structures to create specific products. Taking into consideration how diverse

as being ‘the central compound for life’. (Moulton) An enzyme refers to a protein that folds into complex shapes, which allow smaller molecules to fit inside of them, this is known as the active site. Enzymes are biological catalysts that speed up chemical reactions in living organisms. (Abpischools.org.uk) Trypsin is an enzyme important to the digestion of proteins in the body. The protein is produced in the human body, within the pancreas, in the inactive form of trypsinogen, this is then converted

brown. Apples have apples cells. Inside an apple, there is a molecule named phenol. This molecule is the main reason why apples turn brown. Also there is an enzyme inside an apple cell named polyphenol oxidase. An enzyme accelerates, or catalyze, chemical reactions. So when an apple cell is damaged, it allows molecules of oxygen in the air, to react with phenols and polyphenol oxidase. The oxygen will combine with the polyphenol oxidase enzymes and turn phenol cells into a molecule of melanin. Melanin

Benzoin has a secondary alcohol as well as a ketone functional group which is oxidized into benzil with nitric acid. Oxidation of alpha-hydroxyketone occurs to form alpha-diketone. Hydroxyl group adds as a nucleophile on the carbonyl carbon of alcohol with nitric acid to form organic nitrate. Nitric acid is protonated to form benzil. Rearrangement of alpha-diketone benzil occurs. Hence, the addition of potassium hydroxide to benzil yields a carboxylic salt. Hydrochloric acid added to the potassium

amino acids. The secondary structure is based on the folding of the primary structure. Lastly, the tertiary structure is based on the folding of the secondary structure and its interactions of the side chains. The purpose of an enzyme is to speed up chemical reactions in a cell. Temperature is a factor that affects enzyme activity because as temperature increases the enzyme reaction increases too. Also, pH levels also play a role in affecting enzyme activity. Very high or very low pH levels can result

Title Acids, Bases, and Buffers Purpose: The purpose of this experiment is to increase our understanding of the existence of acids and bases in our everyday lives. Prelab: In this experiment we need to make qualitative observations and comparisons about the nature of solutions. Safety: Acetic Acid This is a weak acid, both in blend and also when present in marinade. As with any acid responsibility should be take when dealing with it and any blows should be treated with camel and drink. Exuberance

Discussion and Scientific Explanations During our first experiment we used blue, yellow and a mixture of blue and yellow to find their transmission using different wavelengths. The blue peaked at 630 nm, the yellow peaked at 410-430 nm and the mixture (green) peaked at 630 nm. Results on Tables 1-3 and Graph 1. We had to find the peak wavelength of each dye to identify the color of the solution. By using the Spec 20 machine the color or the dye that is seen depends on the wavelengths of light to
