Cheat Sheet
- Enzyme Classification & Specificity -
Enzymes which can speed up reactions belong in the biological catalyst category and are classified into six main groups by the IUBMB: oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases. A handy mnemonic "O-T-H-L-I-Lyases" helps you recall the order, and consulting official IUBMB resources (iubmb.org) ensures accurate enzyme class definitions. Mastering this classification is crucial for any biomolecules test or biochemistry enzymes test.
- Carbohydrate Structure & Glycosidic Bonds -
Monosaccharides like glucose (C₆H₂O₆) can cyclize into alpha or beta anomers, and they link via glycosidic bonds (e.g., α-1,4 in maltose, β-1,4 in cellobiose) to form polysaccharides. Remember "Alpha straight chains, Beta bent bridges" as a mnemonic to distinguish bond orientation, a tip endorsed by many university biochemistry curricula (see PubChem entries on carbohydrates).
- Lipid Classification & Functions -
Lipids include fatty acids, triacylglycerols, phospholipids, and steroids, each serving roles from energy storage to membrane structure and signaling. Use the mnemonic "FATS" (Fats store energy, Act as membranes, Thermal insulation, Steroids as hormones) referenced in the Lipid Metabolism section of Lehninger Principles to lock in these functions.
- Amino Acids & Protein Structures -
Amino acids link via peptide bonds in dehydration reactions to build proteins with hierarchical structures: primary, secondary (α-helix/β-sheet), tertiary, and quaternary (e.g., hemoglobin). To memorize essential amino acids, recall "PVT TIM HALL," a classic student mnemonic found in many biochemistry exam prep guides.
- Enzyme Kinetics & Michaelis-Menten -
The Michaelis-Menten equation (v = (Vmax·[S])/(Km + [S])) describes how reaction velocity depends on substrate concentration, with Km equal to the [S] at half Vmax. Visualize a Lineweaver-Burk double reciprocal plot to linearize data - "Y-intercept is 1/Vmax, X-intercept is -1/Km" - a strategy commonly taught in NCBI tutorials on enzyme kinetics.
