In vitro, poorly iodinated thyroglobulin (Tg) is hydrolysed at the same rate whether it is enclosed in thyroid or in liver lysosomes, while fully iodinated Tg is degraded faster inside liver lysosomes. After in vivo TSH administration, thyroid lysosomes hydrolyse fully iodinated Tg as fast as do liver lysosomes.
