Non-steroid hormones are made of amino acids, so they are proteins. True or false

Non-steroid hormones are made of amino acids, so they are proteins.

The statement is true.

Non-steroid hormones are derived from amino acids. Along with norepinephrine and epinephrine, they are hormones called amines, since amino acids make up proteins; they are considered proteins which are synthesized in the inner part of adrenal gland or the adrenal medulla.

Non-steroid hormones are water soluble thus, they do not enter the cell, but instead, they bind to plasma membrane receptors, creating a second messenger or a chemical signal inside the target cell.
