Hospital pharmacies and drug manufactures have various gelatin capsules that they can put drugs into, which will only dissolve in acidic or basic media, once they pass the mouth. This will be done to control where the drug will be introduced into the human digestive tract. We do not want things dissolving in the mouth or oral cavity. Additionally, most drugs will have several different functional groups in their structure, or we can consider them polyfunctional group molecules. With that said, please answer the following questions in order: a) Where will a capsule designed to dissolve in a basic environment dissolve, after it is swallowedwith a glass of water? b) What will happen (if anything) to a part of the drug molecule that is an amine salt, once the capsule dissolves? (Consider what will happen to it in the same location In the digestive tract where the capsule dissolves.) c) What will happen (if anything) to a part of the drug molecule that is a carboxylic acid, once the capsule dissolves? (Consider what will happen to it in the same location in the digestive tract where the capsule dissolves.)

One of your patients, a six-year-old girl who suffers from Sickle cell anemia, an inherited blood disorder in which red blood cells are abnormally shaped and fragile, leading to a short supply of red blood cells.  These abnormal cells can also get stuck in small vessels, which prevent blood flow, leading to fatigue, pain and other severe complications. What molecules make up each single peptide? Deoxynucleotides (dNTPs)   Nucleotides (NTPs)   Amino acids   DNA   RNA

A polypeptide has: many peptide bonds O 4 peptide bonds O 2 peptide bonds O 3 peptide bonds O 1 peptide bond

1- (True or False) Adjacent nucleotides are joined by covalent bonds that form between the –OH group on the 3` carbon of one nucleotide and the phosphate on the 5` carbon on the next.   2- (True or False) if a solute is in an aqueous solution, then by definition an hydration shell has formed around it.   3- (True or False) When exposed to water, phospholipids will self-organize into lipid bilayers, and spheres.
