An amino acid is usually more soluble in aqueous solvent at pH extremes than it is at a pH near the isolelectric point of the amino acid. (Note that this does not mean that the amino acid is insoluble at a pH near its pl.) Which of the following statements correctly explains this phenomenon? (Select all that apply.) At very low or very high pH, the amino acid molecules have increased charge, thus form more salt bonds with water solvent molecules. The neutral charge of an amino acid molecule at its isoelectric point will make the molecule hydrophobic. At pH values far from the ispelectric point, individual amino acid molecules have greater kinetic energy, thus more readily stay in solution. At pH extremes, the amino acid molecules mostly carry a net charge, thus increasing their solubility in polar solvent. Submit Answer Try Another Version 3 item attempts remaining
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.
