We have peptide hormones that are formed from proteins, we have our steroid hormones that are formed from cholesterol and we have tyrosine derivative hormones that are formed from tyrosine amino acids. So let's discuss these three different types of hormones. Let's begin with our peptide hormone. So the peptide hormone is formed in the rough endoplasm reticulum of our cell and then moves on to the Golgi apparatus. Inside the Golgi complex, the peptide hormone can basically be modified in some way or form. For example, we can add a sugar component onto the peptide hormone.
