Monomer - Monosaccharides: Glucose, galactose, and fructose are all examples of the monomer – monosaccharides.


Monomer – Amino acids: Glycine, tryptophan, and lysine are all examples of the monomer - amino acids.


Oligopeptide: Oligopeptide is a protein composed of 3-10 amino acids. Oligos are classified as a short stretch (10 or so) of monomers.


Peptide Bonds: Peptide bonds are a component of proteins. Peptide bonds are associated with protein macromolecules. Peptide bonds link amino acids together in the formation of proteins. Peptide bonds are not a part of nucleotide composition.


Polar Covalent Bonds: Polar covalent bonds are created between oxygen and hydrogen when they bond to form a water molecule. The unequal sharing of their electrons (polarity) is a requirement for the formation of Hydrogen bonds, that hold water molecules together (through ionic attraction).
