    therapy agents, including others based around porphyrin, absorb between 650-850 nm, thus allowing for deeper penetration of activating radiation into tissues.4 According to a study by Wormald et al.,5 another 3 porphyrin-based compound, known commercially as verteporfin, also shows promise in the treatment of macular degeneration by selectively halting the growth of harmful blood vessels under the retina. The photochemical and optical properties of porphyrin compounds have also made them a target of

  • Congenital Erythropoeitic Porphyria ( Cep )

    1581 Words  | 7 Pages

    URO-synthase is an enzyme involved in the metabolism of the tetrapyrrole compound porphyrin, which composes heme. Heme performs a variety of biological functions but is most commonly known for being a component of hemoglobin, helping it to provide oxygen to tissues throughout the body. Specifically, URO-synthase functions to convert a linear

  • Porphyria is a Disease in which the Body does not Produce Porphyrins

    the body. In particular, there is an insufficiency of the body to process porphyrins which are a metal-containing pigment. However, porphyria is actually a group of diseases with the commonality of the accumulation of porphyrins or porphyrin precursors. Porphyria is derived from the Greek word porphyrous meaning reddish-purple. Urine from patients display a reddish-purple hue due to the presence of excess amounts of porphyrins. This is a rare disease with the most common type porphyria cutanae tarda

  • What´s Supramolecular Chemistry Essay

    2001 Words  | 9 Pages

    Supramolecular chemistry actually represents a fairly simple concept.“In contrast to molecular chemistry, which is predominantly based on the covalent bonding of the atoms, supramolecular chemistry is based up on intermolecular interactions, i.e on the association of two or more building blocks, which are held together by intermolecular forces”. When molecules get larger, they have the ability to stick together and that allows the formation of larger assemblies of molecules that are not bonded to

  • Electronic Devices And The Human Central Nervous System

    1417 Words  | 6 Pages

    Electricity in both everyday electronic devices and in the human Central Nervous System is created through the flow of charged particles. However, in electric circuits, charge is carried by moving electrons through a conductive wire, whereas in the brain, impulses are carried by ions, or charged molecules. Electrical signals in the brain mainly take place in neurons, which are nerve cells that specialize in transferring nerve impulses. Changes in the concentration of ions in a neuron cause changes

  • Importance Of Chemistry : The Citric Acid Cycle

    1814 Words  | 8 Pages

    Abstract The citric acid cycle (CAC), also known as the Krebs cycle and the tricarboxylic acid cycle, is a stage of cellular respiration. The role of the cycle is to oxidise fuel molecules and to provide precursors in the form of carbon skeletons for other metabolic pathways (e.g. fatty acid synthesis, amino acid synthesis etc.). The CAC is described as amphibolic, as it has both catabolic and anabolic functions. Catabolism is the breaking down of substances to provide chemically available energy

    Metallobiomolecules METALLOBIOMOLECULES CONTENTS 1. Introduction Metallobiomolecules 2. Classification Metallobiomolecules 2.1. Transport and of to Storage Proteins 2.2. Oxygen binding Today scientists try to explore the chemistry basis behind the biological processes. As a result of this, new areas have evolved such as bioinorganic chemistry and bioorganic chemistry. In this section we will talk about an important concept in bioinorganic chemistry called “Metallobiomolecules”. Metallobiomolecules

  • Function and Structure of Hemoglobin and Myoglobin Essay

    822 Words  | 4 Pages

    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

  • Polymer Coatings With Radiation Detection Functionality

    Polymer Coatings with radiation detection functionality. Mritunjay Sharma Zhuo Yang Supervised by Professor Steve Yeates & Prof. Francis Livens 1. Introduction Nuclear conversion of an atomic nucleus from one form to another is known as radioactivity. These conversions are accompanied by nuclear radiations, major nuclear radiations are alpha, beta and gamma radiations these are ionisations radiations and hence are dangerous to living beings these radiations
