Textbook Question
Chapter 5, Problem 9P
A mutant form of polypeptide hormone angiotensin Il has the amino acid composition (Asp, Arg, Ile, Met, Phe, Pro, Tyr, Val)
The following observations are made.
• Trypsin yields a dipeptide containing Asp and Arg and a hexapeptide with all the rest.
• Cyanogen bromide cleavage yields a dipeptide containing Phe and Pro and a hexapeptide containing all others.
• Chymotrypsin cleaves the hormone into two tetrapeptides, of composition (Asp, Arg, Tyr, Val) and (Ile, Met, Phe, Pro)
• The dipeptide of composition (Pro, Phe) cannot be cleaved by either chymotrypsin or carboxypeptidase
What is the sequence of angiotensin II?

Can koch's postulates of disease causation be applied to non-microorganism disease pathogens (such as molecules)?
Here is my literature Beta Carotene HPLC analysis graph.
Can you help me explain what each peak is at each retention time?
Thank You :D
I have a literature B-Carotene HPLC graph in which showcases a retention time of roughly 23.6 and 25.1.
Please help me compare my two different Anti-Oxidant Juice graphs. (Attached)
The juices provided are: V8 Carrot Ginger Blend and V8 Original Blend
Noticing the HPLC graphs I saw no peaks for the Original Blend for B-Carotene.
However the Carrot Ginger Blend showed similar peaks --> Why is this reason?
Please explain in terms of Retention time and Area (Under Curve).
Thank You!
