Myoglobin consist of single polypeptide chain that made up of 153 amino acid and ahs a size of 18 kDa. Its three-dimensional structure was first determined by X-ray crystallography by John Kendrew in 1957. Myoglobin is a typical globular protein in that it is a highly folded compact structure with most of the hydrophobic amino acid residues buried in the interior and many of the polar residues on the surface. X-ray crystallography revealed that the single polypeptide chain of myoglobin consist of
Marine organisms continue to amaze scientists with their physiological adaptations that allow them to live and thrive in the largest unexplored habitat known to man. Carl Zimmer argues that “most fish without lungs die” because “lungless fish pump their blood in a simple loop.” Therefore, fish are restrained by a lack of oxygenated blood flow that the heart can receive and will die if they exercise too hard because the heart simply won’t receive enough oxygen to sustain intense exercise. In order
Rhabdomyolysis is a disease that involves a rupture of skeletal muscle, causing myoglobin, along with electrolytes and other intracellular proteins to leak in to circular system (Bagley et al, 2007). It is the result from the destruction of muscle fibers that make their way into the bloodstream, which take over the renal system hindering the kidneys ability to remove waste resulting in kidney failure (Owens, 2013). Rhabdomyolysis is rare and has not been fully documented. According to Efstratiadis
Kidney Failure and Ultramarathoning Four days after winning the Seagate 100 km Ultramarathon in Toledo, Ohio, I was hospitalized for 11 days with Acute Kidney Failure, a direct consequence of the race, possibly exacerbated by the 2400 mg of ibuprofen that I took during the race. In this article, I will describe my race and my hospitalization, discuss similar experiences of two runners after the 1994 Western States (WS) 100 Mile Endurance Run, and tell what I have learned that might be of general
Physiological Adaptations of the Plesiosaur for ‘Holding its Breath’ One hundred and fifty million years ago, large aquatic species of reptile such as the Plesiosaur dominated the ocean, and were pre-eminent predators of the sea. The branch of now extinct Plesiosaurs, or ‘near lizards’, evolved into variant closely related species specialised to take different niches in the food chain. Such species of Plesiosaur include the phenotypically similar Plesiosauroid and Pliosauroid. The physiological
and sixth coordination sites. The fifth coordination site is bound by histidine while the sixth is unoccupied. Haem proteins carry out a range of biological functions, including oxygen transport and storage and electron transfer. Haemoglobin and myoglobin, the major oxygen
Myoglobin store increases when we exercise on regular basis this is because over a long period our bodies adapt itself so it can receive more oxygen so we can exercise over a longer period. Myoglobin is found in our cardiac and skeletal muscles and have adapted for endurance activities (that require oxygen). Increased number of mitochondria: Mitochondria’s
Opercular pumping is a mechanism utilized by certain fish for gas exchange. An opercular pump is used to pump water through the gills in an almost continuous unidirectional flow (SHSU). A dual pump is used in tandem in order to drive the unidirectional flow, both a buccal cavity and opercular cavity work simultaneously. The oral valve along the buccal cavity opens, allowing an influx of water. This influx of water causes an expansion of the opercular cavity, dropping the pressure (Hall). Water then
Deoxyribonucleic acid (DNA) is an acclaimed extraordinary discovery that has contributed great benefits in several fields throughout the world. DNA evidence is accounted for in the majority of cases presented in the criminal justice system. It is known as our very own unique genetic fingerprint; “a chromosome molecule which carries genetic coding unique to each person with the only exception of identical twins (that is why it is also called 'DNA fingerprinting ')” (Duhaime, n.d.). DNA is found in
1) Which of the following is used to distinguish the diagnosis of MI (Myocardial Infarction) from that of Unstable angina? a) Serum levels of Cardiac Biomarkers (Troponin, CK-MB) b) Electrocardiograph (ECG) test c) The presence of S4 Heart sound d) Pain lasts for less than 5 minutes in an MI Rationale The correct answer is A because serum levels of cardiac biomarkers such as troponin and CK-MB are used for the final diagnosis of Myocardial infarction (STEMI, NSTEMI). Electrocardiograph (ECG) testing
have not been implemented long enough to discern health effects. My research uses the mammalian muscle protein, myoglobin, to model the impact of ionic liquids on human tissue. I use visible light, circular dichroism, and fluorescence spectroscopy, as well as Förster resonance energy transfer (FRET) and kinetic absorbance assays developed by my lab to monitor the unfolding of myoglobin in ionic liquid environments. Using these data, I calculated the Gibb’s free energy of the functional protein in
Sodium Nitrates and Nitrites, are two of the most common food additives in America. Nitrites are compounds consisting of one nitrogen atom and two oxygen atoms, while nitrates contain one nitrogen atom, and 3 oxygen atoms. These additives are most commonly used in processed meat products in order to increase shelf life and give these processed meats their distinctive red color and flavor. (UK Food Guide) Nitrates, and Nitrites are in meats such as ham, bacon, corned beef, etc. These additives stop
Meat is Neat Eating meat has been a part of American culture since the day our country was founded. It is used as a means of gathering on holidays and special events, as well as being a source of nourishment for us. Eating meat simply makes us human beings. Although most Americans love to enjoy a juicy steak or a rack of ribs, some people strongly believe that killing animals to eat their meat is not ethical. Humans should eat meat because it has essential health benefits, we are designed to be able
simultaneously. The sarcoplasm is located inside the sarcolemma. Sarcoplasm is the cytoplasm of a muscle fiber, it contains a good amount of glycogen, which is used for ATP synthesis. The sarcoplasm also contains myoglobin, a red colored, oxygen binding-protein, that is found only in muscle fibers. The myoglobin binds oxygen molecules, which are needed for ATP production within the mitochondria. The Mitochondria lie in rows throughout the muscle fiber, strategically close to the proteins that use ATP during contraction
often is their basis for product selection or rejection (Deda et al., 2007). As shown in figure, the pleasing pink shade is the result of the chemical reaction between compounds derived from added nitrite/nitrate and the naturally occurring red myoglobin (MbFeII) leading to the simultaneous formation of the bright red nitrosylmyoglobin (MbFeII NO), in which an axial ligand nitric oxide (NO) is coordinated to the central FeII in heme (Møller and Skibsted, 2002). Nitrate is necessary in a long curing

I was born in one of the countries in Asia, and our staple food is rice. Rice is always at the center of the table, and the rest of the viand surrounds it. Here in the United States, my household still eat rice every day, accompanied by cooked vegetables and meat. My food choices are influenced by culture and family. Vegetables and fruits of my choice are abundant at the International Market and other Asian grocery stores. Vegetables are also available for a cheaper price at the farmers
her article. With these established sources, Wollan is able to use a more intellectual word choice to appeal to people of higher education. Her word choice at times is bland but makes up for it in intellectual superiority. Her usage of the word “myoglobin” to describe the origin of chickens’ meat color and “exorbitant” to describe feed costs suggests that her target audience possesses somewhat of a higher education. Wollan’s word are somewhat effective in that they portray the globalization issue
The trachea is reinforced by cartilage, which supports its structure during dives where the lungs collapse under pressure. This prevents the gas from being forced into the bloodstream, also preventing nitrogen from entering the blood. Increased myoglobin concentrations, increased blood volume, and decreased lung size relative to body size are also adaptations seen in diving mammals (Hooker et al., 2011). Lung collapse, which occurs with increasing pressure and depth during a dive, limits the absorption
Muscles. Unless you are a bodybuilder, you overlook them almost everyday, using them to walk, eat, and do other daily activities. Even though they seem small, muscles are probably one of the only things that help keep you alive. Let’s take a trip into muscles to see what they’re made of, different types, ways they can bend and flex, and what makes them so important in your body. First, let's talk about what muscles are made of. Muscles contain muscle fibers, which are the building blocks of the
