Biology math question! how many peptide bonds?

[B.Sweet.]

a question posed in lecture....

Each red blood cell has 3 x 10^8 hemoglobin molecules in it.
You make 2.5 x 10^8 red cells per day.
Each hemoglobin molecule has 2 alpha chains (146 amino acids) and 2 beta chains (144 amino acids)
How many peptide bond are we forming every second to make hemoglobin????

[Kunal Pandya]

2 alpha chain having 145 x 2 = 290 Peptide Bond
2 Beta Chain having 143 x 2 =286 Peptide Bond

one molecule of hemoglobin having total 576 Peptide bond

2.5 x 10^8 red cell per day, so in one second red cell production is 2.5 x 10^8 divided by 86400 (60 x60x24) and then multiply the result with 3 x 10^8 hemoglobin molecules and finally with 576 Peptide bond and that is answer.

Hope I include everything in calculation
