What is the net charge on serine in basic solution at a pH above its isoelectric point? 2.Suppose you mix serine, arginine, proline and valine together and allow them to form tripeptides. Which of the following will form? Pro-Arg-Val Ser-Arg-Pro Val-Val-Arg Arg-Pro-Val None of the above 3.In the polypeptide Gln-Thr-Glu-His-Ser-Ile-Ser-Arg what is the N-terminal amino acid? 4.What is the C-terminal amino acid?
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.
