1. Sudden Death and Sickle Cell Trait: How Knowing Your Genes Can Save Your Life Dale Lloyd II, No. 39. (The Rice Football Webletter) 2006 After running 16 consecutive sprints of 100 yards each, he collapsed. He died the next day from acute exertional rhabdomyolysis (ER) associated with a genetic condition called sickle cell trait. Learning Set 4 : Lesson 1 : Slide 1

20. Charge –Positive and negative charged amino acids attract each other –Amino acids with the same kind of charge repel each other Hydrophobicity –Hydrophilic amino acids attract water –Hydrophobic amino acids repel water and hydrophilic amino acids –Hydrophobic amino acids attract other hydrophobic amino acids. Cysteines –Cysteines are a type of amino acid. When two Cysteines are next to each other they attract and form a strong bond. These strong bonds contribute to protein shape formation. Red = positive charge (+) K, R, H Yellow = negative charge (-) D, E Green = hydrophobic A, V, L, I, P, M, F, W Blue = hydrophilic G, S, T, N, Q, Y White = cystine C Learning Set 4 : Lesson 2 : Slide 12 “Rules” that amino acids follow
