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.
Primary Structure: The unique sequence of amino acids that makes up a protein or polypeptide chain. Peptide bonds are created by enzyme catalysed condensation reactions and broken down by enzyme catalysed hydrolysis reactions. Breaking down proteins is important in many areas of the body, not merely in digestion.
