- Which of the following is false about cellulose?arrow_forwardChoose 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.arrow_forwardWhich statement about the glycoprotein shown below is true?
