Compare the four chemical classes of hormones with reference to hormones within each class.

To review:
Comparison of four chemical classes of hormones.
Introduction-:
Hormones are the molecules that are produced and secreted into the bloodstream by endocrine glands. These molecules are then taken by the blood stream to target cells where they carry out their actions. Endocrine glands are derived from the epithelial tissues and are ductless unlike exocrine glands.
Explanation of Solution
Based on the difference in chemical structure, hormones have been classified into four major classes:
1. Amines: These hormones are derived from amino acids namely tyrosine and tryptophan. Examples are the hormones released by adrenal medulla, thyroid, and pineal glands.
2. Polypeptides and proteins: These hormones consist of polypeptide chains (chain of amino acids). If the polypeptide chain has less than 100 amino acids, it is called polypeptide. Example is oxytocin. But if it has more than 100 amino acids like in case of growth hormone, it is called proteins.
3. Glycoproteins: In this, protein molecule is attached to one or more carbohydrate groups. Examples are follicle stimulating hormones (FSH).
4. Steroids: These hormones are derived from cholesterol. An enzyme is responsible for cleaving off the side chain which is attached to five-carbon ‘D’ ring in cholesterol molecule to form steroid hormones. Examples are estradiol, testosterone, and progesterone.
Following is the comparison of four classes of hormones:

Sucralfate comes as a 1 gm tablet, famotidine as 20 mg tablets, and doxycycline as 100mg tablets. All are in bottles of 100 tablets.How many total mg are needed for the patient and how many tablets of each would be needed to provide each dose?How many bottles of each would be needed to have available if this patient were to be on this drug regimen for 5 days?arrow_forwardThe patient needs a solution of 2.5% dextrose in Lactated Ringer’s solution to run at 75 ml/hr for at least the next 12hours.
