Cytoplasmic Proteins
● Surrounded by water● Polar amino acids side chains fold to
the outside of the structure● Non-polar amino acid side chains are
protected on the inside of the structure

Membrane Proteins● How does the structure of the cell
membrane affect transmembrane proteins?
● Predict: Label hydrophilic heads of phospholipids, hydrophobic tails of phospholipids, polar amino acid region, and non-polar amino acid region.

Membrane Proteins● Within the amphipathic membrane● Polar amino acids in hydrophilic
region (inner/outer surface)● Nonpolar amino acids in hydrophobic
core● Polar amino acids lining channels so
charged/polar molecules can pass through
