The force constant katr of a backbone Ca – -C bond in a peptide is 250.0 kcal/mol/Angstrom² and the equilibrium bond distance (ro) is 1.49 Angstrom. What is the energy required to stretch this bond so that the bond distance is 1.6 Angstrom? Is such a stretching possible at typical room temperature? (Typical thermal energy at room temperature is 2.5 kJ/mol) Select one or more: O A. 12.7 kJ/mol, No thermal energy at room temperature is not enough to cause the molecule to stretch O B. 1-32 kJ/mol, No thermal energy at room temperature can not cause the bond to stretch O . 250 kJ/mol, yes the thermal energy at room temperature is enough to cause the bond to stretch O D. 0.35 kJ/mol, Yes thermal energy at room temperature can cause the bond to stretch
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.
