Alpha helix

1. Our experiment supported our hypothesis. The optimal temperature for the activity of the human amylase is 37°C. This suggest that enzymes have to adapt to the temperature of the organisms in order to develop work because the normal temperature of human is 37°C. It is important to understand that the enzyme amylase play a role to breakdown, so other enzymes can produce sugar of it. In humans, it is critical to develop work at human’s temperature to continue developing break down the molecules…

Bacteriorhodopsin. They discovered 3 identical units rotated by 120o. Each unit has seven closely packed alpha helical segments, with each alpha helix containing 20-25 predominantly hydrophobic residues with one covalently attached retinal molecule. (White, 1994). The seven transmembrane α-helices are typical of all G-protein coupled receptors. (Lanyi, 1998) The retinal molecule is covalently attached to Lys-216 on helix G by a protonated Schiff base. The location and positioning of the retinal…

protein. First is the primary structure, which is just amino acids linked together with peptide bonds. Next is the secondary structure, the specific geometric shape caused by intermolecular hydrogen bonding of amide groups. These may show in two shapes: alpha helices or beta-sheets. Finally, the protein displays as a fully functional 3-dimensional being in the tertiary structure. Protein Synthesis Numerous steps are taken in protein synthesis. The process begins when one…

Title: How Temperature Affects Protein Detection In Eggs Whites Introduction: Research Objective and Hypothesis The objective of this experiment is to gain a better understanding on how temperature affects how much protein is detected. Understanding how temperature affects the detection of protein can be used to more accurately measure the amount of protein in foods and supplements needed for life. This knowledge can benefit nutritionists and the general population. Hypothesis: If the egg…

The low-density lipoprotein (LDL) receptor is an important protein in human function. LDL receptor is the main protein that binds and carries cholesterol to maintain homeostasis in mammalian cells. In human plasma, it is also the most abundant cholesterol-carrying lipoprotein (Goldstein and Brown, 1987). It plays a major role in the development of atherosclerosis, a chronic disease caused by the accumulation of LDL-cholesterol in the blood. The LDL receptor is also the main protein that is…

OBJECTIVES - To understand protein intake better. - To understand how consuming too much or too little of certain food specifically protein can be unhealthy and do harm to our body over time. - To determine what foods are providing the right type of proteins INTRODUCTION The human body has thousands of different proteins all of which are necessary for staying alive and healthy. Protein is a very important substance that is needed by humans for protein is not just a structural material…

The structure of a protein is made of three-dimensional protein molecules. The first level is made of a linear arrangement of amino acids that creates the peptide chain. The second level is the hydrogen bonds that creates the pleated sheet or alpha helix, which is a coiled or spiral molecule (Mandal 65). The last level describes the overall structure of proteins, which are thin and…

The effect of temperature on the rate of reaction on Enzyme reaction Introduction: This experiment will investigate the effect of temperature on the rate of reaction of the enzyme catalase. The biological catalyst called enzymes increase the rate of reaction without themselves being chemically changed. Enzymes are globular proteins folded into a complex 3-dimensional shape that contains a special surface area called the active site where a specific substrate binds structurally and chemically.…

Marie’s father had a dream of becoming a chemist that he could not achieve because of social and financial obstacles. Marie achieved this goal for her father. During the 1940s, women in science career fields was a new and controversial topic. Marie Daly, with the disadvantage at the time of being African American and a woman, fought the stereotype that women should be “in the kitchen” and was the first African American to earn a Ph.D. in chemistry. Since then, Marie Daly has been a part of many…

Abstract : Proteins are vital components of all living cells and play a critical role in almost all biological processes. Protein structure identification is a significant challenging problem in computational biology. The Protein 's three-dimensional molecular structure (i.e., tertiary structure) reflects its proper function. Therefore, the identification of protein structure is a significant step towards understanding the protein 's function which is an important task to treat diseases,…
