C1q is a 400kDa protein formed from 18 peptide chains in 3 subunits of 6.

For instance, a residue is an individual amino acid in a peptide chain.

This results in the migration of the peptide chain from the nitrogen to the sulfur.

These are added in sequence onto the growing peptide chain, which is attached to a solid resin support.

"I've got the antibodies, but there's a toxic peptide chain attached to it."

Just put it through twice, make sure you don't get any reversed peptide chains.

There is no chemical solution for macrocyclization of a peptide chain.

A polypeptide is a long, continuous, and unbranched peptide chain.

This cycle is repeated to form the desired peptide chain.

In another, she increased the magnesium levels and added a peptide chain.
