is catecholamine a steroid
Basics of Hormone Classification There are two types of tyrosine derived hormones: thyroid hormone and catecholamines. Thyroid hormone is one of the most important in the body because it regulates the development of organs and metabolism. Norepinephrine and epinephrine are catecholamines. Both are stress hormones and are also neurotransmitters.ther examples include LH (lutenizing hormone) and FSH (follicle stimulating hormone). LH acts on the gonads to produce eggs and sperm while FSH stimulates the gonads to produce steroids. Non-tropic hormones behave in an opposite manner.
