Protein in life



PROTEIN AS A TRANSPORT TOOL IN LIFE

Protein Derived from the Greek word "Protos" meaning "most important", is a complex organic compounds of high molecular weight which are polymers of amino acid monomers are connected to each other by peptide bonds. Protein molecules containing carbon, hydrogen, oxygen, nitrogen and sometimes sulfur and phosphorus. Protein plays an important role in the structure and function of all living cells and viruses. Approximately 50% of the dry weight of living organisms is the protein carrier protein has the ability to bind to specific molecules and transporting various substances through the blood stream. The protein functions as a means of transportation have characteristics of spherical bodies contained in the tissue fluid. These proteins are soluble in saline solution and dilute, easily changed under the influence of temperature, salt concentration and easily denatured
A.Hemoglobin
Hemoglobin is a protein compound with iron (Fe) called conjugated proteins. As the core is Fe where the hemoglobin causes the red color of the blood due to the presence of Fe. The function of hemoglobin, red blood cells carry oxygen in the systemic arteries of the lungs to jaringa and back in venous blood with carbon dioxide (CO2) into the lungs. Hemoglobin serves as a carrier of oxygen and carbon dioxide. Hemoglobin molecule is mixed with oxygen to form oxy-hemoglobin. Oxy-hemoglobin formation as easily be reversed (revesibel), allowing hemoglobin and oxygen separation, oxygen levels become free. Thus oxygen biases into the network.
A.Ceruloplasmin
Ceruloplasmin is the major protein that contains copper minerals present in the plasma. Ceruloplasmin activity of the enzyme has ferrioxidase that converts ferrous iron in the form of the cells and in the form of store with transferrin and ultimately used by the bone marrow to the manufacturing process of erythrocytes. Ceruloplasmin is the main form of copper minerals are present in the circulation of the blood (plasma). Forms of Cu in the body bind to a protein complex that is 90% bound to globulin in the form of ceruloplasmin and 10% by albumin. Ceruloplasmin have activity as an enzyme capable of converting ferroksidase iron in the ferrous form of the cells and in the form of store with transferring and ultimately used by the bone marrow to the process of making erythrocytes (erytropoiesis). Ceruloplasmin is α-2-globulin. This protein is blue because it contains copper and carry 90% of copper present in the plasma. Myoglobin myoglobin is a protein that is a constituent of the blood that binds oxygen. Myoglobin unsuitable as an oxygen-carrying protein, but it is effective as an oxygen storage protein. Myoglobin in red muscle tissue that binds oxygen in a state of lack of oxygen to be released so that it can be used by the muscle mitochondria for ATP synthesis are dependent on oxygen.

  1. I have a question guys....would you help me please!

    High CO2 levels in the blood can reduce the binding affinity of Hb O2, is there any idea of us to maintain the affinity of Hb although there is lots of CO2 and CO

  2. hb when there o2 and Co or CO2 at the same time will tend to bind CO and CO2. chemically there is no way that can be done, maybe we could break the tie co or co2 at that time. how that might be done is reduce it by using a mask or use a more sophisticated

  3. I will try to answer. if we are indoors or circumstances full carbon, which we do first is to wear a mask. masks that have the main ingredients are high quality, lining-chip Crystal tourmaline made of nano particles are so fine, work on acupoints facial area. With a wave of bio-ionic, metabolic activation and style, can penetrate deep layers of the skin and will cause a 9 mm micro-frequencies in the area of ​​facial acupuncture points, which is good for
    1. Filtering harmful substances in udara
    2. Improve circulation pernafasan.
    3 Ward radiation and toxins
    as the function of mask above it probably that maintain the HB to bond the oxygen

  4. Excess CO2 in the blood diffuses into the central nervous system to reach the central chemoreceptors. Disistem set up a central nervous CO2 carbonic acid breaks down into hydrogen ions. Hydrogen ions stimulate the chemoreceptor
    Hydrogen ions stimulate the central chemoreceptors resulted in an increase in respiratory frequency and depth of ventilation. Increased frequency of respiratory CO2 perngeluaran reducing carbonic acid and increase pH.

    berdasarlkan explanation above, we can lure that hydrogen ions can stimulate the central chemoreceptors. resulting in increased frequency of CO2 spending.

  5. hemoglobi affinity for oxygen increases as succersive molecule bind oxygen. more binding molecules as oxygen partial pressure increas to the maximum amount that can be bound is reaches. as the limit is approached very little addition binding occurs and the level of curve as hemoglobin
