Thyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine ( T3) and thyroxine ( T4 ). They are tyrosine -based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [2] A deficiency of iodine leads to decreased production of T 3 and T 4, enlarges the thyroid tissue and ...

Specific dynamic action ( SDA ), also known as thermic effect of food ( TEF) or dietary induced thermogenesis ( DIT ), is the amount of energy expenditure above the basal metabolic rate due to the cost of processing food for use and storage. [1] Heat production by brown adipose tissue which is activated after consumption of a meal is an additional component of dietary induced thermogenesis. [2 ...
For an ideal absorber/emitter or black body, the Stefan–Boltzmann law states that the total energy radiated per unit surface area per unit time (also known as the radiant exitance) is directly proportional to the fourth power of the black body's temperature, T : The constant of proportionality, , is called the Stefan–Boltzmann constant.
Triiodothyronine, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate. [1]
