The puromycin can then form a covalent link to the growing peptide chain allowing the mRNA to be physically linked to its translational product.
2.
Surprisingly, the heme appears to have two covalent links to the " C . elegans " protein despite the absence of a second conserved carboxyl group in the active site.
3.
Historically, products arising from the linkage of repeating units by covalent chemical bonds have been the primary focus of polymer science; emerging important areas of the science now focus on non-covalent links.
4.
If parylene is bonded to a printed circuit board ( PCB ) then often the mechanical tie-points allow parylene to exhibit good adhesion as opposed to bonding through covalent links ( chemical bonding ).
5.
ATP transports chemical energy within P i ( phosphate ), the breakdown of the last covalent link of phosphate ( a simple-PO 4 ) liberates energy that is used in reactions where it is needed.
6.
Sharpless and Fokin independently described it as a reliable catalytic process offering " an unprecedented level of selectivity, reliability, and scope for those organic synthesis endeavors which depend on the creation of covalent links between diverse building blocks ."
