Addition to Alkenes

Markovnikov vs anti-Markovnikov - the regiochemistry rule and its exceptions.
Chemistry Simple

Common Functional Groups

Alcohol, aldehyde, ketone, ester, amine, carboxylic acid - the recurring building blocks.

Reaction Coordinate Diagram

Energy vs reaction progress - reactants, transition state, products, activation energy.
Chemistry Rich

Aldol Condensation

Enolate attacks carbonyl - C-C bond formation through a classic mechanism.
Chemistry Medium

Nucleophilic Addition to Carbonyls

Nucleophile attacks the electrophilic C of a C=O - the workhorse organic reaction.
Chemistry Medium

Sugar Anomers and Cyclization

Open-chain glucose cyclizes to alpha or beta hemiacetal - the anomeric carbon.
Chemistry Simple

Polymerization Types

Addition vs condensation - chain growth, by-products, and resulting polymer types.
Chemistry Medium

Spectroscopy Summary for Organic ID

IR, NMR, MS, UV-Vis - what each tells you about an unknown structure.
Chemistry Rich

Retrosynthetic Disconnection

Working backward from product to simpler starting materials - synthetic strategy in reverse.

Biochemistry 13 live

Enzymes, Michaelis-Menten, glycolysis, citric acid cycle.

Chemistry Medium

Michaelis-Menten Kinetics

Enzyme rate vs substrate concentration - hyperbolic with Vmax and Km.
Chemistry Rich

Michaelis-Menten Kinetics (Animated)

Walks through low [S], the Km point, saturating [S], and competitive inhibition; the curve, the active-site occupancy, and the algebraic form update in lockstep.
Chemistry Rich

Enzyme Inhibition Types

Competitive, non-competitive, uncompetitive - distinguishable by Lineweaver-Burk plots.
Chemistry Rich

Glycolysis Pathway

Glucose to pyruvate in 10 steps - net 2 ATP, 2 NADH, 2 pyruvate.
Chemistry Rich

Citric Acid (Krebs) Cycle

Animated 8-step ring grouped into 4 phases: acetyl-CoA entry, decarboxylation with CO2 release, energy harvest (NADH/FADH2/GTP), and OAA regeneration to close the cycle.
Chemistry Rich

Electron Transport Chain

NADH and FADH2 hand electrons through four complexes; protons pumped, ATP produced.
Chemistry Medium

Protein Structure Levels

Primary, secondary, tertiary, quaternary - sequence to fold to assembly.
Chemistry Medium

DNA Double Helix

Antiparallel strands, complementary base pairs (A-T, G-C), major and minor grooves.
Chemistry Simple
