Question 1 Part A: State the name of a disaccharide that contains this molecule (structure B). Part B: A branched polysaccharide made up of many monomers of structure B bonded together is commonly a key component of cell surface membranes when attached to either a phospholipid or a protein. What is the name given to such a polysaccharide when it is attached to a protein in the cell membrane, and what is the function of this polysaccharide? ___ (Structure B attatched) Thank you kindly :)

Question 22: which of the following secondary structures would you expect to find on the surface of a globular protein? Alpha helix Beta sheet Loops between two alpha-helices None of the above because water would disrupt the hydrogen bonding that stabilizes these structures A,B and C as long as the polar and charged amino acid side chains face the surface of the protein.
Which statement about membrane lipids is TRUE? Question 7 options: Glycerophospholipids are found only in the membranes of plant cells. Lecithin (phosphatidylcholine), which is used as an emulsifier in margarine and chocolate, is a sphingolipid. Glycerophospholipids contain fatty acids linked to glycerol through amide bonds. Triacylglycerols are the principal components of erythrocyte membranes. Some sphingolipids include oligosaccharides in their structure.
Question 11. // Hint: Isoelectric focusing separates proteins based on their pI values, and can separate proteins that only differ by a net charge of ±1.±1. Recall that an amino acid residue with a negatively charged R group has a relatively low isoelectric point (pI) where it has zero net charge. Likewise, an amino acid residue with a positively charged R group has a relatively high isoelectric point (pI) where it has zero net charge. Order from Low pH to High pH
Question 21 Which of the following statements concerning unsaturated fats is correct? a They are more common in animals than plants b They contain fewer hydrogen atoms than do saturated fats with the same number of carbon atoms c They are solids at room temperature d They possess no double bonds in the carbon chains for their fatty acids Question 30 The 3’ end of a DNA molecule has a phosphate group hanging off. True False

Why are triacylglycerols not found as part of cellular membranes? Question 4 options: Triacylglycerols are not hydrophobic enough The lack of charge on the triacylglyercols reduces the strength of the interactions with other lipids The shape of many triacylglycerols packed together is incorrect for a lipid bilayer No reason, triacylglyercols are found as part of the cellular membranes
