AL-MED is a place to study medicine from the molecule to the patient: short lessons, practice questions that explain themselves, flashcards and a notebook, with your teachers a message away.

Hemoglobin about 6 nm
Four protein chains, each holding a heme with one iron atom. Oxygen binding at one heme makes the next one bind more easily, which is why the dissociation curve is S-shaped.

A short reading and three questions from Adrenergic receptors, the way they appear in the course. No account needed.
From Autonomic Pharmacology · Adrenergic receptors
Adrenaline and noradrenaline do different things in different tissues because the receptors differ. α₁ receptors on blood vessels constrict them. β₁ receptors on the heart raise its rate and the force of each beat. β₂ receptors in the airways relax the smooth muscle and open them up.
Pick a drug, find its receptor, and you can usually predict what it will do, and what it might do that you didn't want.
Read the full lesson1A patient's blood pressure is falling and phenylephrine is started. Which receptor does it act on to raise the pressure?
2Why can propranolol, a non-selective β-blocker, be dangerous for someone with asthma?
3In cardiogenic shock, dobutamine is chosen mainly for which effect?
Where to start
Every subject opens straight into its modules. Pick one and the first lesson is a tap away.
Medical ChemistryMaster biomedical chemistry for drug action and clinical application.2 modules: Electron Configuration, Enzyme Kinetics
PharmacologyLearn core drug classes, mechanisms, indications and key adverse effects.3 modules: Autonomic Pharmacology, Cardiovascular Pharmacology, Antimicrobials
Public HealthStudy population health, epidemiology and health system management.2 modules: Study Designs, Epidemiology Basics
PathologyWhy cells and tissues fail, and how disease shows itself in structure.7 modules: Cell Injury, Adaptation and Cell Death, Inflammation and Tissue Repair, Immunopathology, Water, Electrolytes, Acid–Base, and Hemodynamics, Genetic and Developmental Disorders, Environmental Pathology and Nutritional Disorders, Neoplasia
Human AnatomyStructure and function of the human body with clinical correlations.3 modules: Cranial Nerves, The Adult Skull, The Vertebral Column and Thoracic CageHow a study session goes
Most sessions follow the same four steps. Each one is a real part of AL-MED, not a promise.
