- Q: Compare And Contrast The Structure Of Collagen And Cellulose
The monomer of collagen is an amino acid whereas the monomer of cellulose is beta-glucose. The monomers in collagen are linked by peptide bonds whereas those of cellulose are beta (1,4)-glycosidic bonds. Collagen is an alpha helix polypeptide with a turn...
- The Polypeptide Chain Is Transferred To Aminoacyl-trna
KEY TERMS:Peptidyl transferase is the activity of the ribosomal 50S subunit that synthesizes a peptide bond when an amino acid is added to a growing polypeptide chain. The actual catalytic activity is a property of the rRNA. Puromycin is an antibiotic...
