Protein

biologically relevant molecules such as proteins, nucleic acids, carbohydrates, and lipids play a key role in signal transduction. Thus, the relative alignment of the two interacting proteins can affect the type of signal produced. Therefore, docking is used for predicting (assuming) both the strength and the type of signal produced. Molecular docking is one of the most frequently used methods in structure-based…

They are made within the nucleolus from 60% RNA and 40% protein, and consist of two subunits, one large and one small. When produced, the subunits stay separate to exit through the nuclear pores: it is only because of their miniscule size that they can fit through. Many ribosomes then bind themselves to the RER, although some stay free in the cytoplasm. Free and bound ribosomes both create polypeptide chains, which are used to make proteins. To create a polypeptide chain the large and small…

year 2009 in Northern England, for every 100,000 males, 16 had DMD (0.016%). DMD affects males before the age of 5 due to a gene mutation on the X chromosome, thus causing males to be more at risk. The gene mutation prevents the translation of the protein dystrophin…

Proteins are complex molecules that serve a variety of functions within the body. Proteins are made up of subunits called amino acids. There are several different types of amino acids such as lysine, aspartic acid, and histidine. Each type of amino acids have their own specific group called R-groups attached to them, this causes them to behave chemically different. The group on the amino acid histidine cause the amino acid to be basic; this feature of histidine makes it have a specific purpose…

2.1.2. Alkaline hydrolysis Alkaline hydrolysis is a simple process in which the protein is solubilized by heating followed by the addition of calcium, sodium or potassium hydroxide as alkaline agents and maintaining the temperature at a range between 25-55 °C (Pasupuleti & Braun, 2010). During alkaline hydrolysis of proteins, some amino acids like serine and threonine are damaged during alkaline hydrolysis, however, tryptophan remains intact. Also, this process causes racemization of amino acids…

the molecular weight of proteins within a sample. The protein sample was from the previous using anionic exchange chromatography to partially purify N-acetyl--D-hexosaminidase, Lab 3. The molecular weight was determined through the interpolation of a standard curve of proteins with a known molecular weight. The molecular weight of band 1 was determined to be 67,640 daltons and band 2 was 44,420 daltons, disproving the hypothesis that the molecular weight of the unknown protein sample was 28,000…

material - DNA that makes up the genes and chromosome. The Ribosome: ~Made of dozens of different proteins as well as RNA, also found in large numbers in the cytoplasm of living cells. Ribosome are typically composed of two subunits: • Large subunit • Small subunit “ Free” Ribosome makes proteins that remain inside the cell, “Bound’’ Ribosome make proteins that are exported from the cell. ~Protein Synthesis ~Chemical reactions is molecules that are brought into contact with one another.…

Illustrations of Macromolecules would be nucleic acids, proteins, and polysaccharides (2 or more sugars). These segments are starches, lipids, proteins, and nucleic acids. Starches consisit completely of glucose monomers and are joined by glycosidic linkages, just found in plants. Lipids are a vast gathering of natural particles that incorporate fats, phosholipids, and steriods that don't blend well in water or by any stretch of the imagination. Proteins are organically working atoms consisitng…

Retrieved from: http://www.bbc.co.uk/newsbeat/article/19449377/dieticians-say- extra-protein-can-do-more-harm-than-good. The article targets its general readership. It draws on statements by the British Dietetic Association (with no citation) to stress the side effects that may be developed by extra protein. It also adds that there is now scientific prove to show same. It gives an…

have essential functions like as source of energy, materials for building new body mass such as muscles, and other molecules with essential functions like hemoglobin, which carries oxygen in the blood. These biomolecules are carbohydrates, lipids, proteins and nuclei acids. Biomolecules are called polymers (large molecules) which are composed of smaller molecules known as monomers. 11.1 Elements Present in Biomolecules Biomolecules are organic compounds, thus they are composed primarily of…
