Cheat Sheet
- Protein Hormones -
Proteins are the primary macromolecule that makes hormones in the body, as peptide hormones like insulin and glucagon are chains of amino acids linked by peptide bonds. Many hormone names end with "-in," which is a handy mnemonic for protein-based hormones (think insulin, oxytocin, prolactin). Understanding their primary to quaternary structures helps you grasp how they fold and bind to specific receptors, as covered in most university biochemistry curricula.
- Steroid Hormones (Lipids) -
Steroid hormones like cortisol, estrogen, and testosterone are derived from the lipid macromolecule cholesterol and play critical roles in metabolism, stress response, and reproduction. Lipids are not polymers, which is a key exception when answering "all of the following macromolecules are polymers except…," making lipids the odd one out. A neat mnemonic is "ster checked out from cholesterol," linking steroid with sterol structure.
- Carbohydrate Polymers -
Carbohydrates are polymers made of monosaccharide units, such as glucose in starch and glycogen, serving mainly for energy storage and structural support rather than hormone function. A classic true statement about macromolecules is that they're built via dehydration synthesis, joining monomers by glycosidic bonds and releasing water. When studying for a macromolecules quiz, remember the general formula (CH2O)n and visualize ring structures in sugars to anchor your understanding.
- Nucleic Acids and Information Flow -
Nucleic acids - DNA and RNA - are macromolecules tasked with storing and transmitting genetic information, not producing hormones. Their monomers, nucleotides, join via phosphodiester bonds, forming long chains that guide protein synthesis, including hormone proteins. When learning functions of macromolecules, slot nucleic acids under "information molecules" to keep the four biomolecule roles straight.
- Four Macromolecule Types Mnemonic -
Remember the four major macromolecule classes - Carbohydrates, Lipids, Proteins, and Nucleic acids - using the mnemonic "CHOP" to ace your functions of macromolecules review. Carbs provide energy, lipids store energy and form membranes, proteins catalyze reactions and include hormones, while nucleic acids handle genetic code. This quick recall trick is a lifesaver during a macromolecules quiz or when checking "which statement is true about macromolecules" under exam pressure.
