hydrogen double bond
Omega-3 fatty acids which are important in human nutrition are: alpha-linolenic acid (18:3, ALA), eicosapentaenoic acid (20:5, EPA), and docosahexaenoic acid (22:6, DHA). These three polyunsaturates have either 3, 5 or 6 double bonds in a carbon chain of 18, 20 or 22 carbon atoms, respectively.
All double bonds are in the cis-configuration, i.e. the two hydrogen atoms are on the same side of the double bond.
Known source of polyunsaturated fats is the cold-water fish including lake trout, mackerel, and salmon. These fishes are a rich source of omega-3 acid which is essential in preventing heart diseases through lowering blood clot and lowering triglycerides. Omega-3 acid is also known to lower high blood pressure.
(Triglycerides: The major form of fat. A triglyceride consists of three molecules of fatty acid combined with a molecule of the alcohol glycerol. Triglycerides serve as the backbone of many types of lipids (fats). Triglycerides come from the food we eat as well as from being produced by the body.) Omega-3 acid is particularly noted in help in weigh control because it contains EPA and DHA which is the long-chain that is only found in marine organisms. This acid is also responsible for the increasing the secretion of a hormone known as leptin which decreases appetite and burns body fat.
The omega-3 acid found in some polyunsaturated fats are also responsible for enabling the body to store carbohydrates in glycogen form so that it will not be stored as body fat. In addition, omega-3 acid prevents inflammation which is a condition that contributes to weight gain.

Which of the following is the type of bond holding Na+ and Cl- ions in a molecule of KI ?
a) ionic bond
b) polar covalent bond
c) nonpolar covalent bond
d) hydrogen bond
e) double bond
It would be an ionic bond, because an ionic bond is characterized by electron movement. In this case on electron from the Na is transferred to the molecule of Cl. Ionic bonds are typically much stronger than covalent bonds due to the strong attraction of opposite charges.

The Hydrogen Bond and the Water Molecule $195 The Hydrogen Bond and the Water Molecule offers a synthesis of what is known and currently being researched on the topic of hydrogen bonds and water molecules. The most simple water molecular, H2O, is a fascinating but poorly understood molecule. Its unique ability to attract an exceptionally large number of hydrogen bonds induces the formation of a dense "hydrogen bond network" that has the potential to modify the properties of the surrounding molecules and their reactivities. The crucial role that water molecules play is described in this book. The author begins by providing an overview of the thermodynamical and structural properties of H-bonds before examining their much less known dynamical properties, which makes them appear as centres of reactivity. Methods used to observe these components are also reviewed. In the second part of the book the role played by the dense H-bond network developed by H2O molecules is examined. First in ice, where it has important atmospheric consequences, then in liquid water, and finally in macromolecules where it sheds some original light on the fundamental question "How is it that without water and hydrogen bonds life would not exist?". This book will be of interest to researchers in the fields of physics, chemistry, biochemistry and molecular biology. It can also serve as a teaching aid for students attending course in chemical physics, chemistry or molecular biology. Engineers involved the water industry would benefit from reading this book, as would scientists working in pharmaceutics, cosmetics and materials. * overview of what is known and being researched on the topic of hydrogen bonds and water molecules * reviews methods used to observe interactions between water molecules and hydrogen bonds * examines role of H-bond network developed by H2O molecules |

The Nature of the Hydrogen Bond $130 Hydrogen bond (H-bond) effects are known: it makes sea water liquid, joins cellulose microfibrils in trees, shapes DNA into genes and polypeptide chains into wool, hair, muscles or enzymes. Its true nature is less known and we may still wonder why O-H...O bond energies range from less than 1 to more than 30 kcal/mol without apparent reason. This H-bond puzzle is re-examined here from its very beginning and presented as an inclusive compilation of experimental H-bond energies andgeometries.New concepts emerge from this analysis: new classes of systematically strong H-bonds (CAHBs and RAHBs: charge- and resonance-assisted H-bonds); full H-bond classification in six classes (the six chemical leitmotifs); and assessment of the covalent nature of strong H-bonds. This leads to three distinct but inter-consistent models able to rationalize the H-bond and predict its strength, based on classical VB theory, matching of donor-acceptor acid-base parameters (PA or pKa), or shape of theH-bond proton-transfer pathway. Applications survey a number of systems where strong H-bonds play an important functional role, namely drug-receptor binding, enzymatic catalysis, ion-transport through cell membranes, crystal design and molecular mechanisms of functional materials. |

Dihydrogen Bond $155 This definitive reference consolidates current knowledge on dihydrogen bonding, emphasizing its role in organizing interactions in different chemical reactions and molecular aggregations. After an overview, it analyzes the differences between dihydrogen bonds, classical hydrogen bonds, and covalent bonds. It describes dihydrogen bonds as intermediates in intramolecular and intermolecular proton transfer reactions. It describes dihydrogen bonding in the solid-state, the gas phase, and in solution. This is the premier reference for physical chemists, biochemists, biophysicists, and chemical engineers. |

Solid Bond $11.19 This rather odd double LP is a patchy, yet good assortment of '60s material that Bond did not put out during that decade, and which remains unavailable on any other release. Nine of the 12 tracks date from 1966, with Bond accompanied by Dick Heckstall-Smith on sax and Jon Hiseman on drums (Jack Bruce and Ginger Baker had by this time left to join Cream). Most of those nine songs are not on the two proper albums he issued in the '60s (The Sound of '65 and There's a Bond Between Us), and though a few did appear on those albums and non-LP singles, these recordings are different versions. While not up to the level of the best cuts waxed by the Bruce/Baker lineup, these Hiseman/Heckstall-Smith-backed numbers are still solid jazzy R&B with that aura of faint menace unique to Bond's mid-'60s work. His singing is particularly effective in its drawn-out anguish on "It's Not Goodbye" and "Springtime in the City" has those uneasy descending chord progressions and creepy R&B black-mass organ that were Bond specialties. "Neighbour Neighbour" and "Walkin' in the Park" aren't as good as the versions he did with Bond and Baker on the first two Graham Bond Organization LPs, but they're different enough to merit hearing. The three remaining songs were done in 1963 with Bruce, Baker, Heckstall-Smith, and John McLaughlin, and are long, straight jazz pieces that are much different in nature. Historically they're interesting, particularly in their documentation of the period in which McLaughlin (who solos well, though his free jazz style was a long way off in coming) was in the band. However, Bond's outfit became much more distinguished as an R&B group than they were as an average jazz one, making the 1963 material more of a curiosity than a highlight of his discography. ~ Richie Unterberger, Rovi Performers: Dick Heckstall Smith - Sax (Soprano), Sax (Alto); Dick Heckstall-Smith - Sax (Alto), Sax (Soprano), Saxophone; Ginger Baker - Drums; Graham Bond - Organ, Vocals, Saxophone, Keyboards; Jack Bruce - Bass; John McLaughlin - Guitar; Jon Hiseman - Drums |
