The smell that first hits you when you open a bag of popcorn is perhaps one of the most satisfying, but it may be harmful to your health.
Chemical Nature of Hormones. Chemically, hormones may be classified as either proteins or steroids. All of the hormones in the human body, except the sex hormones and those from the adrenal cortex, are proteins or protein derivatives.ome endocrine glands secrete hormones in response to other hormones. The hormones that cause secretion of other hormones are called tropic hormones. A hormone from gland A causes gland B to secrete its hormone.
There are two major chemical classes of hormones, peptides (proteins) and steroid hormones. Protein based hormones can be divided into three categories: proteins, peptides and amines. Their differences are essential with their size and what they are synthesized from. Peptides are compounds that consist of two or more amino acids; proteins are compounds that consist of 50 or more amino acids; amines are synthesized from the amino acid tyrosine.
