Hydrogen bonds - Study guides, Class notes & Summaries

True or false: Generally, the total number of nonpolar amino acids has a greater affect on protein structure than the exact order of amino acids in a polypeptide chain. - CORRECT ANSWER-False. The order in which amino acids are linked is unique for each protein and is the most important factor in determining the overall protein factor. True or False: The "polypeptide backbone" refers to all atoms in a polypeptide chain, except for those that form the peptide bonds. - CORRECT ANSWER-False...

The attractions between atoms within a molecule of NH3 are best characterized as A. hydrogen bonds B. ionic bonds C. polar covalent bonds D. London (dispersion) forces E. ion-dipole forces Correct Answer-polar covalent bonds R(g) + 2T(g) ⇌ 2X(g) + Z(g) The reaction mixture above is at equilibrium at 298 K. The value of the equilibrium constant for the reaction is 16 at 298K. If R(g) , X(g) and Z(g) each have an equilibrium concentration of 2.0 M, what is the equilibrium concentrati...

Chem 219 Unit 5 Exam with Correct Solutions Generic formula for alcohols - Answer -R-OH phenol - Answer -hydroxy-substituted aromatic molecules (any compound with an -OH attached to a benzene ring) IUPAC system rules for naming organic alcohols - Answer -- organic alcohols are named by replacing the suffix of the parent chain of the molecule with the suffix -ol - The parent chain is numbered so as to give the hydroxyl group the lowest possible number. (examples: 1-propanol, and cyclohexan...

MetabolismAnabolism+catabolism. the chemical processes that occur within a living organism in order to maintain life. Enzymatic Reactions inside a living organism CarbonCarbon is an element with the atomic number 6, meaning it has four electrons in its outer shell. These electrons can form covalent bonds with carbon atoms or atoms of other elements. This allows a diversity of stable compounds to exist. LipidsA diverse group of Carbon containing macromolecules made up of carbon, hydroge...
