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.
Proteins are linear polymers formed by linking the a-carboxyl group of one amino acid to the a-amino group of another amino acid. This type of linkage is called a peptide bond or an amide bond. The formation of a dipeptide from two amino acids is accompanied by the loss of a water molecule.
