Thyroxine T4: The Energy Source of the Body
What is Thyroxine T4?
Thyroxine T4 is an important hormone in the human body, synthesized by thyroid gland cells and composed of tyrosine and iodine atoms. T4 is a precursor hormone that can be converted into the more active triiodothyronine T3 when needed, which is directly involved in regulating the body’s metabolic processes. A decrease in thyroid hormone levels leads to symptoms such as decreased metabolic rate, fatigue, and weight gain; Elevated levels of thyroxine can lead to symptoms such as increased metabolic rate, palpitations, and weight loss. Thyroxine plays an important role in the formation and functional development of the brain, and is crucial for the normal growth and development of children and adolescents.
Thyroxine T4 Effects
T4 enters cells by binding to thyroxine receptors and activates or inhibits specific gene expression, thereby regulating cellular metabolic activity. T4 affects the basal metabolic rate, which is the speed at which the body expends energy in a resting state. It promotes protein synthesis, fat oxidation, and sugar breakdown, maintaining body temperature and energy balance. Eating iodine rich foods (such as seafood, kelp, etc.) helps maintain normal thyroid function. Long term mental stress may have a negative impact on thyroid health, so it is important to learn how to cope with stress and maintain mental health. Regular examination of thyroid function, including T4 and TSH levels, as well as other related indicators, can detect and treat potential problems early.
