Viral infections are common in babies and children and often cause a minor rash of the skin. These rashes are usually harmless and will go away on their own. Different viruses can cause different rashes, and sometimes different viruses can cause rashes that look the same.
receptors for both lipid-soluble and lipid-insoluble hormones are found within the cell and usually within the nucleus. receptors for lipid-soluble hormones are on or in the cell membrane, whereas receptors for lipid-insoluble hormones are inside the cell.
Structures dictate if the hormone prefers to be surrounded by water or fat (water or fat soluble), which determines: Three general structures are known. back to top Water vs. Fat Soluble. Most water-soluble hormones, like the amino acid derivatives and peptides, can travel freely in the blood because they like water. However, they are repelled by lipid or fatty structures such as the membranes that surround the cell and nucleus.
