Why there are different amounts of energy released for popcorn and peanuts Peanuts and Popcorn comprise of different molecular compounds which contribute to their different amounts of energy given off during what should have occured during the experiment. For example, Popcorn comprises mainly of simple carbohydrates, whereas the peanut is comprised of proteins and lipids which contain higher energy densities. The differing energy densities of lipids and carbohydrates ultimately come down to the…

The Portrait of Luther Burbank Do you know russet potato derives its name from Luther Burbank? The russet potato is one of Burbank creations, and is the most used potato by the MacDonald’s restaurants. The Portrait of Luther Burbank by Frida Kahlo, is a painting of oil and Masonite created during 1931, this portrait was inspired in the scientist and horticulturist Luther Burbank whom Kahlo represented as one of his own experiments. This Frida Kahlo’s painting shows a man whose feet are a tree…

III. RESULTS AND DISCUSSION III.1 A. dorsata and T. itama bee bread composition Laboratory analysis of A. dorsata bee bread showed that percentage of protein reached 13.82% (wet weight) and 19.96% (dry weight), lipid 7.80% (dry weight), fiber showed a value of 3.38% (dry weight) and 44.52% (wet weight). All of components in A. dorsata bee bread are placed in the range given by Compos et al., (2008) (Table 1). Table 1. Detailed composition of A. dorsatabee bread (dried mass). Main components…

1.10. Uses of Lactic acid Lactic acid and some of its derivatives (salts and esters) are used in three main applications: foods, polymers, and industrial. Figure 2: Uses of lactic acid [22] 1.10.1. Food The food industry is the traditional large consumer of lactic acid and lactate salts. It is mainly used as an acidulant and preservative. Lactic acid has a mild acid taste and does not overpower weaker aromatic flavors. Since it occurs naturally, it does not introduce a foreign element into…

1.2.3 Gelatin Gelatin is a translucent, colorless, brittle (when dry), flavorless food derived from collagenobtained from various animal raw materials. It is commonly used as a gellingagent in food, pharmaceutical drugs, photography, and cosmetic manufacturing. Substances containing gelatin or functioning in a similar way are called "gelatinous". Gelatin is an irreversibly hydrolyzed form of collagen, wherein the hydrolysis results in the reduction of protein fibrils into smaller peptides, which…

The purpose of this experiment was to discover if Crayola Washable Markers are really nontoxic, or even as safe as the dyes used in food. To answer this question, we used paper chromatography to identify the dyes in blue, orange, and green Skittles Sweets and Sours candy and Crayola Washable Markers. In this paper chromatography experiment, the mixture to be separated was spotted 1.5 centimeters from the bottom of chromatography paper, which was then dipped in the solvent, a 0.1 percent salt…

Sterols in plants are almost completely derived from acetyl-coenzyme A (acetyl-CoA). Acetyl-CoA is dimerized to acetoacetyl-CoA that then forms 3- hydroxy-3-methylglutaryl-CoA (HMG-CoA) by a condensation reaction. HMG-CoA is reduced to mevalonic acid by 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR), a rate-limiting step in human isoprenoid biosynthesis. HMGR over-expression in transgenic tobacco plants resulted in increased levels of total sterols, indicating that HMGR is a limiting enzyme…

3.3.3: Phytochemical analysis The leaves and bark extracts were tested for some secondary metabolites like-saponins, tannins, alkaloids, anthraquinones, phlobatannins, flavonoids, terpenoids, reducing sugar and poly phenols. Test for reducing sugar: Mixture of 1ml or 1gm of plant sample is taken in a test tube and 10ml deionized water is added in it after this a few drops Fehling solution (1ml Fehling solution A and B) is also mixed and heated at 1000C in a water bath. The Brick red…

Fausto B. Mariano L. Daniel E. Diego R. Ms. Gudiño Science 3B 27/OCT/15 Lab Report Osmosis -Research Question: How will uncovering the egg shell by exposing the egg to vinegar will make it possible to understand the osmosis process in action? -Background information Diffusion: It's the net movement of molecules down a concentration gradient. This process allows small molecules like water and carbon dioxide to cross the Plasma Membrane. (Movement of dense areas to less dense areas.)…

Protein Purification Practical Report Student Name : Noel Murphy Date : 28 February 2015 UF/DF Practical Question Report Ultrafiltration (UF) and Diafiltration (DF) steps are carried out prior to every chromatography step and post the final polishing chromatography step. These UF and DF steps are vitally important, the UF step concentrates the protein product into a smaller volume of buffer, while the DF step alters the conditions the protein product is sitting in i.e. Buffer exchange.…
