Must know what an alpha helix is
Give this one a try later!
The carbonyl group of one peptide bond is hydrogen
bonded to the amino group of a peptide bond four amino
acids away. This gives rise to a helix making a complete turn
every 3.6 amino acids.
Describe the unique properties of water that make them particularly important to life.
Give this one a try later!
Water has polarity and can interact with other polar molecules due to its
asymmetric charge distribution. Can also do hydrogen bonds with other
water molecules. The electrical charge effects of water can partially shield
, charges between ions making it a universal solvent. polar molecules are
soluble in water
Be able to draw Serine and Cysteine

Describe the difference between pasteurization and sterilization
Give this one a try later!
Pasteurization is low heat treatment food preservation method that kills
microorganisms present in food. This does not change the nature of the
food and preserves the nutrient value of food.
Sterilization is high heat treatment that extends shelf life by a few months...
kills all microorganisms
Calculate the pH of a solution given a concentration of a strong acid or base.
Calculate the concentration of H+or OH-given a pH.

, pH = -log[H+] ex: what is the pH of a 0.1M HCl solution? [H+]=0.1 M so then
pH= -log[0.1] = pH= 1.
Describe the difference between prokaryotes and eukaryotes
Give this one a try later!
Prokaryotes- "before" not just bacteria also includes archaea.
NO nucleus
Eukaryotes- "true" includes plants, animals, fungi.
with nucleus and bigger than prokaryotes.
Explain how a protein's structure defines its function.
Give this one a try later!
Proteins fold up into specific shapes according to the sequence of amino
acids in the polymer, and the protein function is directly related to the
resulting 3D structure. Proteins may also interact with each other or other
macromolecules in the body to create complex assemblies.
Explain why covalent bonds are critical to biological systems.
Give this one a try later!
They are very strong and stable in aqeuous enviornment because they are
not charged like ionic bonds are.
