What are two stereoisomers called when they have multiple stereocenters and are *not* mirror images of each other?
What is the charge and chemical folmula of the polyatomic ion carbonate?
CO3, with a charge of -2.
What are the four basic polymers we primarily study in biochemistry, and can you name their individual repeating units and give an example of each?
Nucleic Acids, a monomer of which is a nucleotide, such as adenine. Proteins, or polypeptides, a monomer of which is an amino acid, such as proline. Carbohydrates, or polysaccharides, a monomer of which is a monosaccharide, such as glucose. Finally Lipids, which do not actually typically form polymers, but are nonetheless ubiquitous to life, such as cholesterol, steroids, or triglycerols.
