Disaccharide composition calculated from LC-MS peak integration (Fig. 5) using appropriate response factors

TriS, NS6S, NS2S, and NS disaccharides arise from the S-blocks, and 2S6S, 6S, 2S, and 0S disaccharides arise from the N-blocks. From these groups of disaccharides, the NS:NAc ratio in the resulting products can be calculated for: di-block NS, 28:72; di-block SN, 44:56; tri-block NSN, 31:69; tri-block SNS, 57:43.

	TriS	NS6S	NS2S	NS	2S6S	6S	2S	0S
NS	17.4	10.3	0.2	0.1	3.6	60.7	0.4	7.4
SN	30.2	13.1	0.4	0.2	3.9	32.3	0.3	19.6
NSN	19.0	11.5	0.3	0.3	2.0	30.3	0.7	35.9
SNS	33.1	23.9	0.7	0.7	1.3	22.2	0.2	19.9
