“Hydrophilic vs Hydrophobic Chemical Signals”

Hydrophobic/lipophilic -> Hormones (all steroid hormones, some of the amines)

-Non-polar molecules

-Able to pass through the membrane

-can bind to Internal Receptors

-Can't dissolve in the blood, but must be transported by proteins.

Hydrophobic/lipophilic

Not able to be stored in vesicles, but must be made as needed by the cell.

Hydrophobicity

Classification of chemical signals

hydrophilic/lipophobic

Hormones (all peptide hormones are there)

What is hydrophilic/lipophobic?

- Polar molecules

-Not able to pass through the molecules

-Must use external receptors

-Able to be dissolved in Blood

-Able to be stored in vesicles

-able to be made ahead of time and stored until needed

hydrophilic

water loving

Hydrophobic

Water fearing

lipophilic

fat loving
