In secondary structure, the interactions of the R groups give a protein its specific three-dimensional tertiary structure.

In secondary structure, the interactions of the R groups give a protein its specific three-dimensional tertiary structure. Correct Answer False

In the tertiary structure of a protein the interactions of the R groups give a protein its specific three-dimensional tertiary structure. Global but restricted to the amino acid polymer. Formed and stabilized by hydrogen bonding, covalent (e.g. disulfide) bonding, hydrophobic packing toward the core and hydrophilic exposure to solvent.

Phytase, an enzyme produced by Aspergillus niger can be adsorbed on microcrystalline cellulose powder (MCCP). The adsorption follows a Langmuir isotherm and the maximum concentration of the protein that can be obtained on the adsorbent is 70 mg cm-1. At a concentration of 50 mg L-1 of protein in the solution, the concentration of protein on the adsorbent reaches 35 mg cm-1. It is desired to recover 90% of the protein from 1.5 liter of the cell free culture filtrate containing 220 mg L-1 protein by addition of MCCP to the solution. The concentration of the protein adsorbed on the solid at equilibrium will be:
Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer :

Statements : About 50 per cent of the animal by-products - hair, skin, horns etc. is edible protein. American chemists have developed a method of isolating 45 per cent of this protein. They used an enzyme developed in Japan to break down soya protein.

Conclusions :
I. Americans have not been able to develop enzymes.
II. Animal by-products protein has the same composition as soya protein.
