  1. Trace element
    An element that is present in small quantities in a living organism
  2. Amino acids
    (alpha amino acid) A compound consisiting of a carbon atom to which are attached a primary amino group, a carboxylate group, a side chain (R group), and an H atom
  3. Carbohydrate
    A compound with the formula (CH2O)n where n is greater than or equal to three. Also called a sacchardie
  4. Monosaccharide
    A carbohydrate consisting of a single sugar molecule
  5. Nucleotide
    A compound consisting of a nucleoside esterified to one or more phosphate groups.  Nucleotides are the monomeric units units of nucleic acid
  6. Lipid
    Any membrer of a broad class of macromolecules that are largely or wholly hydrophobic and therefore tend to be insoluble in water but soluble in organic solvents.
  7. Monomer
    A structural unit from which a polymer is built up.
  8. Polymer
    A molecule consisting of numerous smaller units that are linked together in an organized manner.
  9. Residue
    A term for a monomeric unit after it has been incorporated into a polymer
  10. Peptide bond
    An amide linkage between the alpha-amino group of one amino acid and the alpha-carboxylate group of another.  Peptide bonds link the amino acid reidues in a polypeptide.
  11. Phosphodiester bond
    The linkage in which a phosphate group is esterified to two alcohol groups (eg. two ribose units that join the adjacent nucleotide residues in a polynucleotide)
  12. Glycosidic bond
    The covalent linkage between two monosacchrides units in a polysaccharide, or the linkage between the anomeric carbon of a saccharide and an alcohol or amine.
