Choose any/all that apply to lipids. Farnesyl and palmitoyl can act as anchors for proteins that function at the cell membrane. Steroids like cholesterol that function as membrane lipids have a rather unique structure when compared to the circulating steroid hormones such as testosterone. Phosphoglycerides contain a phosphorylated alcohol that is buried deep within the hydrophobic core of the plasma membrane. A fatty acid that has 16 carbons and two cisdouble-bonds would have a higher melting point than a fatty acid that has 16 carbons and three cis double-bonds. Fatty acids are stored as glycolipids in adipose tissue. Omega-3 fatty acids such as alpha-linolenate are precursors to important hormones and are constantly being synthesized in the pancreas.

Which of the following is true of sphingolipids? They always contain glycerol and fatty acids. They may be charged, but are never amphipathic. They contain two esterified fatty acids. Phosphatidylcholine is a typical sphingolipid. The sphingosine backbone is O-linked to a head group.
Which of the following statements is incorrect? The rigidity of a saturated fatty acid is based on the strong bonding between sp3-hybridized carbon chains. Glycerophospholipids are the most abundant lipids in cellular membranes. In delta notation of fatty acid nomenclature, the numbering starts at the α-carbon from the carboxylic acid end. Hormones, such as testosterone, estradiol and progesterone are examples of steroidal lipids.
Which of the following functions is NOT or cannot be performed by lipids? They can serve as chemical messengers. They can help in the selective permeability of membranes. They can form pores for the thermodynamically favored passage of ions across membranes. They can bind to DNA response elements to control gene expression.
