Assignment Help Biology
Reference no: EM132931560

a) Proteins A and B have isoelectric points (pI) of 8 and 11, respectively, but the same molecular mass.

i) What is the difference in the amino acid composition between protein A and protein B, which makes protein B have a higher isoelectric point?

ii) Briefly describe a method that can be used to separate the two proteins from each other.

b) Pick the proteins from the following molecules, and say something about function: Glycogen, phospholipid, hemoglobin, receptor tyrosine kinase, rRNA, cholesterol, alcohol dehydrogenase, ATP, cellulose, DNA ligase, pyruvate, enolase, NADPH
