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.
![The text reads:
"The net charge on the following amino acid is [x] at pH 10."
The image shows the chemical structure of the amino acid cysteine. The structure is depicted with the following components:
- A central carbon (C) atom.
- An amino group (NH₂) attached to the central carbon.
- A carboxyl group (COOH) with a double-bonded oxygen (O).
- A thiol group (SH) attached to the central carbon.
- The central carbon is also bonded to a hydrogen atom (not explicitly shown in the image).
For educational purposes, examine the ionizable groups at pH 10:
- The carboxyl group (COOH) is deprotonated to form COO⁻.
- The amino group (NH₂) remains neutral at this pH.
- The thiol group (SH) can be deprotonated to form S⁻ at higher pH levels, including around pH 10.
Considering these ionizations:
- The net charge at pH 10 would be calculated based on the COO⁻ and any other deprotonated groups.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F56b89a6c-6ca3-4f25-9a44-1409c69966fc%2F8a8b1abd-c84c-4239-ad5a-40b1a17194e8%2Fhmdf6vi_processed.png&w=3840&q=75)
