Summary

The complete set of biochemical pathways for cholesterol synthesis (mevalonate pathway via HMGCR), uptake (LDLR-mediated endocytosis), efflux (ABCA1/ABCG1), esterification (ACAT/SOAT1), and catabolism (CYP46A1 to 24S-hydroxycholesterol). Brain cholesterol is synthesized locally and is essential for myelination, synaptic function, and membrane integrity. Dysregulation is linked to Alzheimer's and Niemann-Pick disease.
