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 ...

MCAT Study Setcovalent bond formed via the sharing of electrons between two elements of similar EN bond order refers to whether a covalent bond is a single, double, or triple bond. As bond order increases, bond strength increases, bond energy increases, bond length decreases ionic bonds formed via the transfer of one or more electrons from an element with a relatively low IE to an element with a relatively high electron affinity - cation: postiive - anion: negative

MCAT 2023Phase Diagram - correct answer a graph showing the conditions at which a substance exists as a solid, liquid, or vapor a line separates the regions that correspond to the solid and liquid phases. For most substances, since the solid phase is denser than the liquid, this line has a positive slope. This indicates that it is possible to convert the liquid substance into solid by increasing pressure. Since the opposite is true for water, however, the line between these regions has a nega...
