41. Apotirucallol becomes a tetranortriterpenoid when the four terminal carbons from the side chain are cleaved off. 42. CCL2 is anchored in the plasma membrane of endothelial cells by glycosaminoglycan side chains of proteoglycans. 43. Common protein design programs use rotamer libraries to simplify the conformational space of protein side chains . 44. Tunicamycin homologues have varying molecular weights owing to the variability in fatty acids side chain conjugates. 45. The aromatic side chain of phenylalanine is hydroxylated by the enzyme phenylalanine hydroxylase to form tyrosine. 46. The enzyme therefore forms a binding tunnel around the substrate and side chain interactions control specificity. 47. Or maybe an-OH side chain for every 17. 48. The side chains of the modified version, which Bell Labs named F15, fill in the empty space. 49. These side chains contain three monosaccharide residues. 50. It has the shape of three Olympic rings with a side chain hanging off the middle ring.
