What characterizes amino acid hormones compared to other hormone types?
Understand the Problem
The question is asking about the characteristics of amino acid hormones in comparison to other types of hormones. The focus is on understanding the unique properties of amino acid hormones and how they differ from peptide hormones and other hormone types.
Answer
Amino acid hormones are water-soluble, not lipid-soluble, and bind to surface receptors.
The final answer is that amino acid hormones are water-soluble and insoluble in lipids, located on the surface of target cell receptors, and examples include hormones derived from tyrosine and tryptophan.
Answer for screen readers
The final answer is that amino acid hormones are water-soluble and insoluble in lipids, located on the surface of target cell receptors, and examples include hormones derived from tyrosine and tryptophan.
More Information
Amino acid hormones are typically synthesized from amino acids such as tyrosine and tryptophan, which dictate their solubility and receptor location. Examples include epinephrine and norepinephrine.
Tips
Common mistakes include confusing amino acid hormones with steroid hormones, which are lipid-soluble and pass through plasma membranes. Always check solubility and receptor location.
