∙ 14y agoIf a hormone is lipid soluable then it passes right through the phospholipid bilayer and does not need a receptor. It can dock directly with a transcription factor. Steriods, for instance.

Chemically hormones belong chiefly to two molecular groups called?
Chemically hormones belong chiefly to two molecular groups. The two groups are the steroids and the amino acid based molecules.
Are peptide bonds weak?
hydrophilic "water loving" Hormones 2 groups- -Peptides (short protein)- such as insulin - Catecholamines: hormones epinephrine and noreepinephrine Low lipid solubility, High water solubility Lipophilic "Fat Loving" Hormones 2 Groups - Thyroid hormones - Steroid Hormones --> sex hormones such as testosterone High lipid solubitilty, poorly soluble in water Cholesterol precusor (molecule is not a hormone)
Is AlPO4 soluble in water?
No, it is not water soluble.
Is Glutamine water soluble?
No it is not soluble in water it is soluble in chloroform, alcohol, methnol
Is dolomite water soluble?
Dolomite is not water soluble.
What type of hormones bind to receptors located on the membrane?
Water-soluble hormones. Insulin and epinephrine
What type of hormones bind to receptors located on cell membrane?
Water-soluble hormones. Insulin and epinephrine
What is the difference between protein hormones and steroid hormones and how they communicate with their target cells?
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.
Hormones in the body can be organized into two types fat-soluble and water-soluble what are fat-soluble?
Steroid
What are steroid hormones soluble in?
Lipids (fat-soluble), they can therefore be administered orally.
Are peptide hormones water soluble?
Both. Some amines such as epinephrine are water soluble while thyroxine is a fat soluble amine
Examples of water soluble and lipid soluble compounds in living organism?
Amino acid based hormones such as Human Growth Hormone is an example of water soluble compounds. Steroid hormones and thyroid hormone are examples of lipid soluble compounds in living humans.
Which hormone is water soluble and therefore binds extracellular receptors?
Insulin and epinephrine
It is impossible for water-soluble hormones to regulate gene expression since only lipid-soluble hormones can penetrate the cell membrane true or false?
false
Is calcitonin water soluble?
yes..but Other thyroid Hormones like T4, T3 are fat-soluble unlike calcitonin..
Chemically hormones belong chiefly to two molecular groups called?
Chemically hormones belong chiefly to two molecular groups. The two groups are the steroids and the amino acid based molecules.
What water-soluble hormone would most likely bind to what membrane proteins?
Channel linked receptors bind to neurotransmitters. (also called ion channels and ligand gated ion channels) A ligand is the signal molecule i.e the neurotransmitter. Hormones bind to intracellular receptors because hormones are non polar and can cross the cell's plasma membrane. (also called cytoplasmic receptors)
