Hospital unit clerks play a vital role in managing communication and information in hospital nursing units, and are the first point of contact for patients. Learn medical terminology, how to process medical orders, communication skills, administrative procedures, and computer skills.
Protein Structure. Proteins are polymers of amino acids. The amino acids of a protein are linked by peptide bonds. Alpha helices and beta pleated sheets are characteristic of a protein's secondary structure. Electronegative oxygen and nitrogen atoms leave hydrogen atoms with partial positive charges. Peptide bonds link together the amino acids of a protein's primary structure.
Although R-groups of some amino acids contain amino and carboxyl groups, branched polypeptides or proteins do not occur. The sequence of monomer units in a macromolecule is called the PRIMARY STRUCTURE of that macromolecule.Each specific macromolecule has a unique primary structure.e will conclude this section of the course with a consideration of denaturation and renaturation -- the forces involved in loss of a macromolecule's native structure (that is, its normal 3-dimensional structure), and how that structure, once lost, can be regained.
