Protein

Macromolecules are large molecules that are composed of smaller units. The four major macromolecules are carbohydrates, lipids, nucleic acids, and proteins. Carbon is the primary component of the four macromolecules. Carbon's molecular structure allows it to bond in many different ways and with many different elements. A Monomer is an atom or small molecule that may bind chemically to other monomers to form a Polymer Different monomers make up a polymer. Polymers combine to make a molecule, and…

The study is aimed at the comparison of homologous protein BLOCKs using different diversity parameters (MDRs, DHPs and MCRs etc) that are formulated using positional frequencies of observed hetero-pairs and homo-pairs of BLOCKs. APBEST, written in AWK programming language, extracts these BLOCK specific parameters. How efficient is the program? Are these parameters correlate with already existing literature reports? To have resolution of these questions, we have implemented the program first on…

1.5. Enzyme-Polysaccharide Interactions Proteins and enzymes have become an integral part of many industrial processes as well as being applied both in cosmetics and in therapeutics. Due to advances in biotechnology and genetic engineering, mass production of protein and enzymes has become feasible. Use of enzymes is environmentally friendly as they catalyse reactions under mild conditions against polluting inorganic catalysts which works in the extremes of pH and temperature. However, this can…

About 20% volume of the mammalian central nervous system comprises of an extracellular matrix that includes proteins, proteoglycans, and glycosaminoglycans (Bignami A et.al 1993). Evolving evidence indicates that the organization and composition of this matrix change throughout the course of normal aging, during neurodegenerative diseases and following central nervous system injury and that these modifications influence a diverse range of cellular behaviors. The central nervous system…

of small proteins. Keratin is the main component of your hair, skin, and nails. Integrin acts a sort of messenger. Cadherin acts a binder, creating the structure of cells. So many different proteins help make the world turn waiting the human body, but they do different things. These are three important proteins. Keratin to is very important to the human body. Keratin is a big factor in making up your hair, nails, and skin. In fact, your hair is 95% keratin This protein works…

within its structure, in which enables it to operate. Within its structure it contains chromosomes, DNA, proteins, chromatin, nuclear membrane, . The nuclear membrane is a thin layer that surrounds the nucleus and it has pores to allow materials to enter in and out of the organelle. This part of the nucleus helps it to function because it allows the nucleus to allow important materials such as proteins, in and out of the organelle. The chromosomes are made up of DNA. These are vital elements in…

fibrosis affects ion transport in epithelial cells b) The CFTR protein regulates the transport of a number of ions; name 2 of these ions. (2 marks) The CFTR protein regulates the transport of Cl- and Na+ c) Explain why a defective CFTR gene could cause Dan to produce very salty sweat. (5 marks) The normal function of the CFTR gene provides instructions for making a protein channel called the cystic fibrosis transmembrane. This protein channel transports chloride ions across the semipermeable…

result for polysaccharides. After that, I preformed the Biuret test, which sees if a substance contains proteins. I first placed 5 drops of each stomach content into the appropriately labeled tube. Next, I added one drop of Biuret solution into each tube. Then, I recorded the result, if the substance changed purple then it contained proteins. Only stomach two and three had a positive trace of protein. With these results I was able to conclude that stomach content one belongs to Margaret…

substitution this is a mutation that exchanges one base for another. For example a change in a single molecule or switching an A to a G. Substitution can also change a codon to one that transmits a different amino acid and cause a small change in the protein. Insertion is another form of mutation which adds extra base pairs into a new place in the DNA. Deletions are mutations that are…

Transferrin is a protein that circulates in the plasma and is encoded by the transferrin (TF) gene. The protein contains 678 amino acid residues, 19 disulfide bonds and has a molecular mass of about 80 kDa. Transferrin has a combination of alpha helices and beta sheets that form an N-terminus and a C-terminus domain (1). The iron ion that binds to the protein binds to two tyrosine, one aspartic acid and one histidine residues. In humans, the major function of transferrin is to regulate the level…
