Identify the planar units present in the following generic protein chain.
Consider the following protein chain:
How many amino acids make the atoms in a planar unit? Why are the units planar?
Find the number of ways four different amino acids can be arranged so that each peptide formed is distinct from the others.
True or False: The chains of alternating peptide bonds and α-carbon atoms are the 'backbone' of a protein.
Enkephalin is a peptide responsible for regulating pain sensation in the body. There are two forms of enkephalin. One is met-enkephalin, which contains methionine and has the following primary structure: Tyr-Gly-Gly-Phe-Met. Provide the complete structural formula of met-enkephalin.
What is described by the primary structure of a protein? Identify the type of bonds or molecular interactions that stabilize the structure.
