species can survive in temperatures approaching -2.5 °C (Bilyk and DeVries 2010) and hence, is well suited to meet the demands of cold temperature survival. The major adaptation of C. hamatus for survival in cold temperatures is the expression of antifreeze glycoproteins (AFGPs) (Bilyk and DeVries 2010) which are absent in most teleosts but necessary for survival in frigid waters (DeVries 1988). Further adaptations of the icefish clade relate to the distinguishing synapomorphy of the group (di Prisco

The need to keep the car radiator cool is to avoid gasket exploding and overheating issues. Overheating of car engine can cause various problems which can empty your wallet. Handling out your car in certain manner will yield good result. Follow of certain tips will help a lot in keeping the engine

Antifreeze There are hazards in and around every automotive shop across the world. Among these hazards are the chemicals used in or on the vehicles themselves. With proper training and information, the handler of these chemicals will be able to protect him/herself from experiencing the dangerous potential of these chemicals. Along with a lot of overseen hazardous chemicals is a chemical found in every liquid cooled engine, antifreeze. Over the years our engines inside of our automobiles have

determines the sequence of amino acids in protein. At first, DNA is decoded. After that, each sequence of bases on one of the chains of DNA molecule is transcribed into a sequence of mRNA, and then translated into the amino acids that build the protein as a combination of a triplet. 2/ The sequence of DNA that encodes a protein are amino acids. 3/ The process that produces RNA by reading DNA is the DNA transcription process. 4/ The process that produces protein by reading RNA is the translation process

temperature environment is made possible by a class of proteins called Antifreeze proteins. Antifreeze proteins (AFPs) and Antifreeze glycoproteins (AFGPs) are polypeptides that are biosynthesized in animals, plants and fungi that prevent ice crystal formation (Griffith & Ewart, 1995). The most widely accepted mechanism for the prevention of ice formation by AFPs and AFGPs is called the adsorption-inhibition mechanism, which describes that the protein binds to water molecules and separates water molecules

G Proteins Proteins play various important roles in inter-neuronal communication. Receptor sites are made up of proteins and the ion channels in the cell membranes are proteins. The link between the receptor sites and the protein channels sometimes is the guanine nucleotide-binding protein, better known as G Protein. (1) The basic structure and function of these shall be explored in the following. In order for neuron communication to occur, the post-synaptic neuron must have receptor sites

How life arose is a question that is fundamental to both philosophy and science. Responses to it enable one, in turn, to answer such questions as, “Who am I?”, “Why am I here?”, and “How do I make sense of this world?” This secondary set of questions can be answered in a myriad of ways for a variety of reasons, but the answer to the first question has only two responses. As Douglas Futuyuma says, “Creation and evolution, between them, exhaust the possible explanations for the origin of living things”

Analysis of Amino Acids by Paper Chromatography Introduction- Proteins may be thought of natural polymers of amino acids, as the composition of proteins is of amino acids. The technique known as paper chromatography is used to separate amino acids for analysis. In this technique small spots of amino acids are introduced to a piece of porous filter paper. The bottom of the paper is then placed in a small bath of an appropriate solvent. The solvent is allowed to rise up the paper. The

Then collect a cylinder of beetroot by pushing the corer into the beetroot and withdrawing it. The cylinder remains inside the corer- so push it out with the end of a pencil. · Collect 3 cylinders, and then cut them into 6 pieces

types of macromolecules that I am going to describe: Proteins, carbohydrates, lipids and nucleic acid. I will also describe the functions and why they are important in our bodies. Proteins ======== Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then folded into a three-dimensional structure unique to each type of protein. The covalent linkage between two adjacent amino acids in a protein (or polypeptide) chain is called a peptide bond.

The Nature of Proteins Proteins consist of carbon, hydrogen, oxygen and also nitrogen. Proteins are macromolecules. They are constructed from one or more unbranched chains of amino acids; that is, they are polymers ( Compound whose molecule consists of many repeated units linked together). A typical protein contains 200-300 amino acids but some are much smaller (the smallest are often called peptides) and some much larger. Amino Acids Amino acids are the building blocks (monomers)

The Transport of Substances Across the Plasma Membrane The plasma membrane or, the cell surface membrane, is made almost entirely of protein and lipid. The plasma membrane controls the movement of substances into and out of a cell. It is partially permeable so some substances cross more easily than others. The lipids found in the membrane are known as phospholipids. Phospholipids are fat derivatives in which one fatty acid has been replaced by a phosphate group and one of several nitrogen-containing

The Functions of Osmosis Osmosis is the passive transport of water through a selectively permeable membrane, a membrane that allows certain needed particles to pass through it more easily than others. Pores in this type of membrane are large enough for water to pass effortlessly through it. The flow of water during osmosis depends on the concentration of a solute either within a cell membrane or surrounding the membrane. Water naturally flows from a hypertonic solution, an area of high

and is bounded by a nuclear membrane, but since a prokaryotic cell doesn't have a nucleus and its DNA is a single, circular coiled molecule that floats freely within the cell and is not bounded by nuclear membrane nor is it complexed with any proteins. In addition to the circular DNA some bacteria also contain plasmids. Prokaryotic cells are far older and more diverse than eukaryotic cells. Prokaryotic cells have probably been around for 3.5 billion years, which is about 2.5 billion years

many different proteins found in food stains. These enzymes only need a low temperature of around 50ËšC, and this means a saving of energy, as less electricity is used by the appliance but the difficult stains are still removed. In the dairy industry, enzymes are used to remove lactose from milk as some people are allergic to lactose. The enzyme lactase is added ... ... middle of paper ... ... assay) are used in hospitals to diagnose certain diseases as specific proteins are detected in

Pepsin and Protein Question Is the rate at which Pepsin digests protein affected by temperature? Prediction I predict that it is affected by temperature. The optimum temperature will be between 30°C and 40°C. This is because the average human body temperature is 37°C. At 0-20°C (which includes the groups 0-10 and 10-20) the pepsin will not digest the protein for a long time. This is because it is a too cold environment for the enzyme to work most effectively and quickly. At 20-30°C

Membranes in Biological Systems Biology is never far from the headlines. You may not know it but biology affects our everyday lives in ways which would bore you! Have you ever wondered what a cell membrane or a cell was made of? Cells are surrounded by thin membranes; it is these cell membranes which separate inside from out, life from non-life. It is believed that a cell or plasma membrane similar those of today's cells defined the boundary of the first cell nearly 4 billion years ago

used to modify the dimensional and sequential data of the molecules. The data can be applied in various ways. Biochemists can rearrange and form amino acids to observe mutagenesis or functions of the proteins, it can also be useful to predict and understand catalytic mechanisms stimulated by proteins. VMD can be useful to a range of audience, molecular structural data obtained from VMD can be integrated with bioinformatics, which will then provide useful information to researchers of biological system

as, UBQLN2, VCP/CDC48 in the UPS and SQSTM1/p62, VAPB and some of the vesicular traffic proteins in autophagy have been suggesting a fragile capacity of proteostasis in vulnerable neurons (Bedford et al., 2008; Deng et al., 2011; Paine et al., 2013; Johnson et al., 2010). Recent genetic and biochemical study revealed that mutations in a unique PXX repeat region of UBQLN2 which is one of ubiquitin like protein family are causative in ALS. The different mutations of UBQLN2 are present in the typical
