I need to be maintained at a normal level in your body for normal growth and development as well as for proper bodily function in you. My absence leads to delayed or arrested development.
My principal function is to stimulate oxygen consumption and thus metabolism in all cells and tissues in the body. I am one of the few hormones with general effects upon all tissues.
Without me, there will be a decrease in the general metabolism of all cells, most characteristically measured as a decrease in nucleic acid and protein synthesis, and a slowing down of all major metabolic processes.
As you can see, it's hard to understate the importance of the role that i play in biology. I am the ultimate metabolism regulator. My reactions and products influence carbohydrate metabolism, protein synthesis and breakdown, and cardiovascular, renal, and brain function.
Without me, an animal's functions and development come to a grinding halt. Tadpoles won't develop into frogs. Untreated human babies are doomed to cretinism, a condition marked by severe mental and physical retardation. Adult humans with low thyroxine levels or hypothyroidism suffer mental slowness, weight gain, depression, and fatigue.
So you reckon that you need me?
