Intramolecular bond - Study guides, Class notes & Summaries

Molecule Unit of matter that results when two or more atoms are joined by covalent bonds Ionic Bond A bond resulting from the electrostatic attraction of a cation for an anion. Brainpower Read More Nonpolar Covalent Bond A bond characterized by an even distribution of charge; electrons in the bonds are shared equally by the two atoms Polar Covalent Bond A bond resulting from unequal sharing of bonding pairs of electrons between atoms Polyatomic Ions Charged g...

intermolecular forces - forces between molecules EX: HCl-HCl intramolecular forces - hold atoms together in a molecule Ex: H-Cl Types of intramolecular forces - 1. Ionic 2. Covalent - Polar covalent - nonpolar covalent nonpolar covalent bond - bond between atoms with same electronegativity polar covalent bond - bond with unequal sharing of electrons the lower the pka the - stronger the acid Buffers are ___ - solutions that resist changes in pH when strong acids or bases ...

MCAT Chem/PhysGenerally, how are proteins formed? The connecting of a string of amino acids via peptide bonds and the folding of this string to create a completed protein. The folding is determined primarily by the hydrophilic and/or hydrophobic nature of the amino acids. Stabilized by hydrogen bonds, disulfide bridges, and other intramolecular forces. Peptide (Amide) Bonds These are formed when the n-terminus of one amino acid attacks the carboxy terminus of another amino acid. Water is ...

Why would covalent bonds break in water? Why can they? - Because more stable or energetically favored bonds could be formed. They can break because the loss of energy by breaking hydrogen bonds in compensated for in the formation of new covalent bonds. Limitation to eukaryotic cells and photosynthesis - The sea slugs that live in symbiotic relationships with cyanobacteria or algae. The algae is not broken down or digested and absorbed into the slug's body. There is then a horizontal gene t...

Classifications of proteins are based on.... correct answer: - position in the cell (membrane/soluble/extracellular) - function (transporter/enzyme/structural/hormone) - other molecules associated w/ it (glycoprotein - sugar, lipoprotein - lipid) A salt bridge is an....bond and is an example of a.....interaction correct answer: ionic, non-covalent Are salt bridges easier to break in biochem? Why? correct answer: - Yes- Interacting w/ surrounding solvent (water) Is an O bonded to a ...
