Etanercept

Although it is known that etanercept is a recombinant human soluble tumor necrosis factor-alpha (TNF? ) receptor fusion protein that decreases its role in disorders that involves excess inflammation in animals, mainly in humans, including autoimmune diseases such as ankylosing spondylitis, psoriasis, hepatitis C, rheumatoid and psoriatic arthritis, it obviously shows that the effect of… View Article

Understanding Enzymes and the Factors that Affect Them

Abstract The researcher conducted this experiment in order to investigate how various factors effected enzymes. Those factors were the concentration of the enzyme, the temperature it had to work in, and the pH level of the solutions as well. All three were hypothesized to speed up the rate at which the enzyme acted. A series… View Article

AP biology FRQ

A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino, carboxyl and R groups. These R groups that are in the amino acids are what determine… View Article

Biomolecules Case

1.What are macromolecules? Give examples. Macromolecules are large complex molecules that occur in colloidal state in intercellular fluid. They are formed by the polymerization of low molecular weight micromolecules. Polysaccharides, proteins, and nucleic acids are common examples of macromolecules. 2. Illustrate a glycosidic, peptide and a phospho-diester bond. (a) Glycosidic bond is formed normally between… View Article

Bradford Protein Case

The appearance of blue color showed the present of protein in the BSA dilutions. The more diluted the solution was, the less blue it was. The R2 value of the standard curve of BSA dilution was obtained to be 0.9972, which is close to 1. The closer to 1 the R2 value was, the more… View Article

Circular Dichroism and Secondary Structure of Proteins

Proteins are vital to an organism life; they are involved in nearly all cellular functions. It is an essential part of enzymes, the cellular membrane, active transport, protein synthesis and wound healing. Because one relies so heavily upon proteins and its function the structure of proteins is also very important. “The way a protein will… View Article

Protein Synthesis

Although the size of DNA maybe microscopic its purpose is omnipotent and crucial to humanity. Without deoxyribose nucleic acid our genes would cease to exist, and the characteristics of the individual would disappear too. As it wanders in the nucleus DNA is replicated and transmitted to assist other parts of the cell. DNA transfers RNA… View Article

Identification of food constituents in milk

Objective •To compare and analysis the composition of two different types of unknown milk, K1 and K2. •To determine the differences of the fat content in milk samples, K1 and K2. •To compare the reducing sugar in the both samples of milk, K1 and K2. •To compare the protein concentrations in the both samples of… View Article

Protein Purification

Protein purification is the series of processes to isolate a single type of protein from a complex mixture. This is vital to extract and characterize the protein of interest. However, before doing so, it is important to release the protein from the subcellular organelles. This step is also known as homogenization. This step can be… View Article

Diffusion and Osmosis

NGSSS: SC.912.L.14.2 Relate structure to function for the components of plant and animal cells. Explain the role of cell membranes as a highly selective barrier (passive and active transport). SC.912.L.14.3 Compare and contrast the general structures of plant and animal cells. Compare and contrast the general structures of prokaryotic and eukaryotic cells. AA Background: (Source:… View Article

Herbicide Resistance

Superweeds threaten to negatively impact U.S. soybean, cotton and corn production. These crops were previously controlled effectively by the herbicide glyphosate (Round up). Glyphosate works by stopping the enzyme EPSP synthase by gumming up the enzyme. This renders the EPSP incapable of production. If EPSP synthase is not present, plants stop producing necessary proteins. Without… View Article

As enzymes normally only catalyse one reaction the substrate has to fit in the specific shape (active site) and if it… View Article

Why Are Proteins Important

Proteins can easily be addressed as one of the most important molecules in animal cells. There are many varieties of protein molecules which allow a vast range of biological activities in the cell.( Williams, G.(2000))’Proteins are big compound with large molecular masses’’(Williams, G.(2000)) whose main chemical constituents are hydrogen, carbon ,oxygen and nitrogen. A protein… View Article

When I am upset, all I crave is bacon. It seems to bring out the good in everything. The sky is brighter when I eat bacon; the grass is greener; the glass is half full. Bacon just makes everything seem alright. I feel reenergized. Alert. Happy. Bacon is my substance of choice for mood-enhancement, as… View Article

Why are cells microscopic?

This research assignment will discuss why cells are usually microscopic in size, given that they need to be able to exchange material with their surrounding environment. The cell is highly organised with many functional units or organelles (Spurger).A membrane is a fluid mosaic which consists of proteins, lipids and carbohydrates which seperates the cell from… View Article
