Be sure to answer all parts. Give the amino acid sequence of an octapeptide that contains the amino acids Lys, Pro, Tyr, Ile (2 equiv) , Gln, Trp, Phe, and forms the following fragments when partially hydrolyzed with HCl: Lys-Ile-Phe-Pro, Phe-Pro-Gln-Tyr, and Trp-Ile-Lys.

Activity: Write the line structure of each of the following peptide at pH7 and identify how many peptide bond in each number. 1. Glycyl-valyl-serine 2. Threonyl-cysteine 3. Isoleucyl-methionyl-aspartate

Need help, please. Answer choices are provided below for drop-down questions. 1. The overall charge of this protein at pH 7 is Drop-down answer choices are [positive, negative, or neutral] 2. In the first dimension of 2-D PAGE, this protein's isoelectric focusing point is  Drop-down answer choices are [between 4 and 6, between 6 and 8, or between 8 and 10] 5.  A mole of the above protein weighs ____ g. For 1 mL of a 3 mM solution of the above protein, you would need to weigh out ____ Drop-down answer choices are [g, mg, mcg, ng, or pg]  (number and unit, at least one non-zero integer to the left of the decimal point, don't round)

please answer

During  biological nitrogen fixation, microbial plant symbionts uptake_________and converted it to__________?

a. Suppose that you have the peptide Ala-Gly-Tyr-His-Leu and you treat it with FDNB and then 6M HCl. Draw the structures of all the products that you will have in solution (assume all reactions to go to completion).
