Determine whether a salt bridge interaction can occur between the side-chains of each of the amino acid residue pairs listed below. Assume that the protein is at physiological pH. a) aspartic acid and lysine b) aspartic acid and glutamic acid c) aspartic acid and arginine d) aspartic acid and alanine HINT: A salt bridge is an attractive force between the positive formal charge on a polar basic amino acid residue's side-chain and a negative formal charge on a polar acidic residue's side-chain. For more help: See chapter 13 part 4 and part 5 videos or chapter 13 section 4 in the textbook.
Neutral Amino Acids
Amino acids which do not have any charge on them are neutral amino acids.
Globular Protein
The globular proteins refer to the shape of protein specifically spherical in nature apart from spherical form fibrous, disordered and membrane-bound proteins exist. These globular proteins are miscible in water and form a colloidal solution rather than other types which might not exhibit solubility. Many classes of the fold are found in globular proteins, which render them a sphere shape. Globular fold containing proteins usually are referred to by the term globin.
Dimer
Dimers are basic organic compounds, which are derivates of oligomers. It is formed by the combination of two monomers which could potentially be strong or weak and in most cases covalent or intermolecular in nature. Identical monomers are called homodimer, the non-identical dimers are called heterodimer. The method by which dimers are formed is known as “dimerization”.
Dipeptide
A dipeptide is considered a mixture of two distinct amino acids. Since the amino acids are distinct, based on their composition, two dipeptide's isomers can be produced. Various dipeptides are biologically essential and are therefore crucial to industry.
I don't get it at all. Can you help me?
