Correct me if I'm wrong: number of amino acids in human, gorilla, & horse hemoglobin

  1. Apr 12, 2012 #1
    I'm doing a lab and my biology teacher specifically told me to count the amino acids found in the hemoglobin of the aforementioned animals. Since I'm sure I'm not the only one who'd rather not count, and I cannot for the life of me find the numbers on the Internet, I figured I would post what numbers I have. I should mention that my mom helped me.

    DISCLAIMER: Whether or not this would be considered cheating depends entirely upon the cheating policies you have to follow.

    Number of alanine amino acids in humans, gorillas & horses: 15
    Number of valine amino acids in humans: 18

    Fellow PF members, feel free to correct the numbers I post, but please do not add the number of any other amino acids, otherwise I may just skip counting and I don't really know what my teacher would do if he ever found out I "cheated" and and looked it up - though he might be OK.

    1) You can find the amino acid sequences of these hemoglobins in various databases, such as Genbank (http://www.ncbi.nlm.nih.gov/genbank/).

    2) There are tools available that will count the numbers of each type of amino acid, for example, http://web.expasy.org/protparam/ or http://www.bioinformatics.org/sms2/protein_stats.html

    I'll also note that the question is a bit unclear since hemoglobin is composed of four molecules of two different polypeptides (α- and β-globulin).

    Yes. Oh, and PF members, please feel free to post the exact numbers of all the amino acids. I already turned in my lab this morning, but I still want these numbers to be posted in this thread because it is the only result on Google that anyone searching for "number of x amino acids in (human/horse/gorilla) hemoglobin" will care about.
