produce energy for the body
Components of a phospholipid - ✔✔One glycerol molecule, two fatty acid chains, one phosphate group
(water-soluble head).
Steroid composition - ✔✔lipids that take form of 4 interlocking hydrocarbon rings

Four levels of protein structure - ✔✔primary - sequence and number of amino acids that link together to
form the peptide chain
secondary - natural bend of parts of
the peptide chain. most common shapes are
oalpha helix (spring shape) and obeta-pleated sheet (accordion shape).
tertiary - overall shape of a single
molecule
quaternary - two or more protein chains join to form a macromolecule.
Define and give an example of a structural protein - ✔✔Long, stable, rigid, and water-insoluble. A fibrous
protein. i.e. collagen, keratin.
