Amino acid

dimension over which a hypothetical monopolist could initiate ‘a small but significant and non-transitory increase in the price of its goods’ (ACCC v Metcash Trading). Prima facie, the product dimension of the market in this scenario consisted of the amino acid lysine, which is commonly added as a nutritional supplement in poultry and swine feed. From the perspective of feed manufacturers, there is no viable substitute for factory synthesised Lysine. Lysine occurs naturally in plant matter,…

Cell penetrating peptides are proteins or peptides that typically consist of 5-30 amino acids. These peptides are unique in that they are able to cross cell membranes and other barriers throughout the body such as the blood brain barrier, intestinal and nasal mucosa, and even skin. Using CPPs, scientists are now able to explore their potential as a means of transporting cargo into cells and across bio barriers. With their ease of preparation and generally nontoxic nature, CPPs have gained a…

Proteins are important to human physiology and play an essential role in bodily function. Isoforms of proteins can result in increased susceptibility to many diseases. One such isoform can be observed in the polymorphic protein APO-E, which exists in the ApoE2, ApoE3, and ApoE4 isoforms (Mahley and Rall, 2000). The most common isoform is ApoE3, which is considered the normal isoform for the known physiology of APOE. APOE plays a role in transporting and metabolizing plasma cholesterol and…

Ubiquitin-conjugating partners of CHIP: In section 3, after " fate of substrates": E2’s are the family of enzymes, having highly conserved ubiquitin conjugating domains. These enzymes, in combination with E3s, play an important role in determining the fate of substrate proteins by selecting a lysine residue on which ubiquitin moiety must be added. In section 3, after Murata, et al. 2003: An in vitro study has shown that CHIP, with the aid of UbcH5 and UbcH6, two other E2s, can efficiently…

of Macromolecules Using Benedict’s, Biuret’s, Sudan III, and Lugol’s Solution Betty Ngo Introduction Macromolecules are the critically important large molecules that fall into four main classes: carbohydrates, lipids, proteins and nucleic acids. Macromolecules are polymers which are built up by monomers. Monomers become polymers from the process dehydration reaction and polymers are broken apart by the process hydrolysis. Macromolecules are critically important to all living organisms…

My type of molecule, Proteins should be the MVP because they protect the body, help to create new molecules, give structure to many parts of the body, send messages, and they transport and store molecules and cells. The first characteristic of my molecule is its solubility. Keratin is insoluble to water this is why keratin waterproofs the skin. The second property of Keratin is it’s luster, keratin is shiny. The third characteristic of keratin is it’s texture, the texture of keratin is hard…

bonded sequences of amino acids and this happens through dehydration synthesis where complex molecules are broken down to simple components. Secondary structure happens within the protein and can repeat multiple times and this happens from the folds by the Hydrogen bonds. Finally, you reach tertiary structure where the final 3-dimensional shape is shown by the complete polypeptide chain. This is also where the R group interactions take place and with Huntington’s, the amino acid glutamine is…

for both microassays and standard solutions. The analysis provides a linear response with concentrations of Bovine Serum Albumin (BSA) from 1 to 140 microliters. The reagent used was the combination of Bradford Reagent-Brilliant Blue G in phosphoric acid and methanol. The dye molecule is mostly deprotonated and converted on the process to a reddish colored species that have the potential to bind to other proteins. Once this red colored species bind to a protein the bound dye molecule transforms…

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…
