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

How can IDPs can gain a stable conformation? Question 45 options: By interacting with other proteins. They already exist in their final structure due to protein folding. By interacting with partially folded intermediates. By testing multiple partially stable intermediate structures to find the most energetically favourable structure
Question 1Predicting Secondary Structure Which of the following peptides is more likely to take up an -helical structure, and why? (a) LKAENDEAARAMSEA (b) CRAGGFPWDQPGTSN
Suggest a reason why amino acids are usually more soluble at pH extremes than they are at neutral pH. (Note: This does not mean that they are insoluble at neutral pH).
Which statement is true regarding denaturation process? Question 21 options: Protein experiences hydrolysis as it denatures and alters its structure. Denaturation is the process of altering the shape of a protein that involves breaking the amide bonds. Denaturation is the process of altering the shape of a protein without breaking the amide bonds. As protein denatures, new peptide bonds form with the added amino acids.

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.
