Isoleucine (ile/i: phenylalanine (phe/f, tryptophan (trp/w, cysteine (csy/c, uncharged polar side chains, asparagine (asn/n, glutamine (gln/q, serine (ser/s, theronine (thr/t, tyrosine (tyr/y, optical isomers, alpha carbon is asymmetric allowing for two mirror image isomers, l and d. The principal types of weak noncovalent bonds: van der waals attractions: Yes, there are ions present, this is due to h+ ions spontaneously leaving their water molecule, creating h3o+ and oh- ions becoming present. Molecular weight of water is 18g/mol, 1l of water = 1kg of water, 1000/18 = 55. 6m of water molecules, (1 x 10-7) x (55. 6) = 1. 8 x 10-9 is the ratio (h3o+ to h2o). The d- forms of the amino acid may not be able to bond together to produce a protein or could make a dysfunctional protein. Q2-15 a. proteins are so remarkably diverse because each is made from a unique mixture of amino acids that are linked in random order.
