on the basis of the 13c relaxation behavior ( t1 and noe ) the dynamics of the alpha-carbons appear to be unique to each amino acid type and glycosylation state , with alpha-carbon mobilities decreasing in the order gly greater than ala = ser greater than thr much greater than monoglycosylated ser/thr approximately greater than disaccharide linked ser/thr .
