MCAT Biochemistry - Macromolecules, Kinetics, Thermodynamics, & The Plasma Membrane
This MCAT Biochemistry Review Summary Page is by no means an exhaustive review of MCAT Biochemistry. Our summary is only meant to highlight key points that are most helpful for the current MCAT. For a detailed list of MCAT Biochemistry topics see our MCAT Topics List. We have placed a couple of MCAT Biochemistry practice questions at the bottom of this page, and you can access more practice questions in our Free MCAT Practice Test, or our many full-length MCAT Practice Tests. You may also be interested in Gold Standard's new, completely free premium app: MCAT Biochemistry for iPhone, MCAT Biochemistry for Android.
For MCAT Biochemistry, it helps to understand vocabulary, definitions, and relationships. In some respects, learning this "language" of biochemistry will decrease your need to memorize information and increase your understanding of MCAT Biochemistry content. Unlike most undergraduate Biochemistry exams, MCAT Biochemistry is far more likely to ask reasoning questions than to ask for the intermediate or enzyme in a pathway that you are expected to review.
||Polymerizes to form . . .
||Dimer, trimer, tetramer, oligomers, etc.
||Dipeptide, tripeptide, tetra/oligopeptide, etc.
|Monosaccharides ('simple sugars'**)
||Disaccharide, tri/tetra/oligosaccharide, etc.
||Nucleotide dimer, tri/tetra/oligomer, etc.
||Polynucleotides, nucleic acids
*There are exceptions. For example, in certain circumstances polypeptides are considered monomers and they may bond non-covalently to form dimers (i.e. higher orders of protein structure).
**Note that disaccharides are also sugars (i.e. sucrose is a glucose-fructose dimer known as 'table sugar'; lactose is a glucose-galactose known as 'milk sugar').
