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.
A monomer is the basic unit that binds chemically to other molecules to form a polymer. For lipids, the monomers are glycerol and fatty acids. For proteins, the monomers are amino acids. For nucleic acids, the monomers are nucleotides which is made of a pentose sugar, a nitrogenous base and a phosphate group.
