1 Free T4 (Free Thyroxine) â considered a precursor hormone, T4 is converted to T3 as required by cells throughout the body; levels of T4 are generally much higher than T3.  Total T4 (Total Thyroxine) - Most T4 in the blood is bound to carrier proteins which make it biologically inactive. Total T4 includes unbound (free) T4 plus T4 that is bound to carrier proteins in the blood.
For example, we know that Alzheimer's disease involves having too much of a chemical called beta-amyloid in the brain. The blood-brain barrier has two specific proteins involved in this process â one brings the beta-amyloid out of the bloodstream into the brain, while the other protein does the opposite.Perhaps keeping the beta amyloid out of the brain might be a prevention, or even a cure, for Alzheimer's disease.or example, we know that Alzheimer's disease involves having too much of a chemical called beta-amyloid in the brain.
