- The following is a block diagram for a glycerophospholipid where the building blocks are labeled with letters and the linkages between building blocks are labeled with numbers. a. Which building blocks are fatty acid residues? b. Which building blocks are alcohol residues? c. Which linkages are ester linkages? d. Which linkages involve a phosphate residue?arrow_forwardGive numerical answers to the following questions about the structure of a cholesterol molecule. a. How many six-membered rings arc present? b. How many amide linkages are present? c. How many hydroxyl substituents are present? d. How many total functional groups are present?arrow_forward21-100 What are the functions of a cell membrane? To what extent is a bilayer that consists entirely of lipids able to carry out these functions?arrow_forward
- 21-101 Glycerophospholipids tend to have both a positive charge and a negative charge in their hydrophilic portions. Does this fact help or hinder lipid packing in membranes? Explain.arrow_forwardPlease explain eacharrow_forwardTake a look at this molecule, and then answer the questions in the table below it. CH₂OH CH₂OH H H H H OH H OH H OH OH H OH H OH Is this a reducing sugar? yes α no Does this molecule contain a glycosidic bond? If you said this molecule does contain a glycosidic bond, write the symbol describing it. yes no If you said this molecule does contain a glycosidic bond, write the common names (including anomer and enantiomer labels) of the molecules that would be released if that bond were hydrolyzed. If there's more than one molecule, separate each name with a comma. В G ローロarrow_forward
- e X 1. During the hydrogenation of a cis-linked unsaturated fat, it will always convert to a trans fat when using a catalyst such as Nickel. True or False 2. Triglycerides always have three fatty acid chains linked to a glycerol group, and these fatty acids always have to have the same number of carbons in theirarrow_forwardI don't understand it. Can you help me to explain this question with these answers?arrow_forwardThe melting points of oleic acid, C18:1 delta 9 cis, versus elaidic acid, C18:1 delta 9 trans, are 16.3 degrees Celsius and 44.8 degrees Celsius respectively. What do the data imply about the two fatty acids?arrow_forward
