A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. For many molecules, the sharing of electrons allows each atom to attain the.

For the synthesis of PU elastomers, the reaction of a diisocyanate (either aromatic or aliphatic), a macrodiol (a polymer diol), and a chain extender (ChEx; typically a small-molecule diol or a diamine) together results in a copolymer of the macrodiol sequence, termed the soft segment (SS), and the diisocyanate-ChEx sequence, termed the hard segment (HS) [].

Chemical compound – Functional groups: Chemists observed early in the study of organic compounds that certain groups of atoms and associated bonds, known as functional groups, confer specific reactivity patterns on the molecules of which they are a part. Although the properties of each of the several million organic molecules whose structure is known are unique in some way, all molecules that.

Note that a diene has two C=C bonds, a triene has three C=C bonds, a tetraene has four C=C bonds and these are alkene modifications. A simple straight chain hydrocarbon diene has a formula C n H 2n-2.Isoprene is the common name for 2-Methyl-1,3-butadiene which has a methyl (CH 3) group attached to the second carbon atom and a double bond attached to the first and third carbon atoms.

Polar covalent bonds. carry a partial charge. Peptide bonds are an example of a nonpolar covalent bond, which are important for making living cells. One atom has higher electronegativity than.

In the structure shown at the top of the page, R represents a side chain specific to each amino acid. The carbon atom next to the carboxyl group (which is therefore numbered 2 in the carbon chain starting from that functional group) is called the α–carbon.Amino acids containing an amino group bonded directly to the alpha carbon are referred to as alpha amino acids.

How does ferritin store iron? Ferritin has the shape of a hollow sphere. Inside the sphere, iron is stored in the Fe(III) oxidation state. It is incorporated in the mineral ferrihydrite, [FeO(OH)] 8 [FeO(H 2 PO 4)], which is attached to the inner wall of the sphere. To release iron when the body needs it, the iron must be changed from the Fe(III) to the Fe(II) oxidation state.
