preprohormones
prohormones. These prohormones are inactive and need to be cleaved or modified to become biologically active peptide hormones.
peptide hormones and catecholamines (epinephrine and norepinephrine)
Hormones and vitamins are synthesized from various biochemical precursors, primarily involving proteins, carbohydrates, and lipids. For example, cholesterol serves as a precursor for steroid hormones, while amino acids are used to produce peptide hormones. Additionally, vitamins often derive from dietary sources or can be synthesized in the body from other compounds, such as vitamin D from cholesterol in response to sunlight. Overall, the synthesis of these essential biomolecules involves complex metabolic pathways and enzymatic reactions.
Amine hormones are derived from amino acids, such as epinephrine and dopamine, and are typically water-soluble. Peptide hormones are made up of short amino acid chains and are also water-soluble. Peptide hormones include insulin and growth hormone.
Peptide neurotransmitters are synthesized in the cell body of neurons in the endoplasmic reticulum and Golgi apparatus. Once synthesized, they are packaged into vesicles and transported down the axon to the nerve terminal for release.
The peptide hormone is used to include hormones that are peptides,proteins,glycoprotein,and modified amino acids. peptide hormones binds to a receptor protein in the target cell's plasma membrane; a realy system leads to conversion of ATP to cAMP(cyclic adenosine mono phosphate).peptide hormones are the first messenger and cAMP and calcium are the second messengers. peptide hormones does not enter the cell; second messenger sets an enzyme cascade in motion.

That question is not a full sentence. Please learn to speak before attempting to ask a scientific question on plant peptide hormones. Thank you!
Peptide based hormones exert their effects on a cell by way of second messengers (cAMP or PIP) pathways. Steroid based hormones exert their effects on a target cell via direct gene activation.
peptide hormones
There are three types. They are peptide,steroids and amines
