Two common proteins found in the hormones are angiotensin II and basic fibroblast growth factor-2 proteins. However, parathyroid hormone-related protein are also found in hormones.

hormones (peptides = protein)
Steroid hormones arelipid-soluble and can dissolve easily into the cell membrane of the target cell to connect with receptors. Protein hormones are water-soluble and connect with receptors at the membrane because it can't diffuse through the membrane.
Amino acids are the building blocks of all proteins, including hormones made of proteins.
