It is one of the two components of starch, the other being amylose. It is insoluble in water. Glucose units are linked in a linear way with α(1→4) bonds. Branching takes place with α(1→6) bonds occurring every 24 to 30 glucose units. Its counterpart in animals is glycogen which has the same composition and structure, but with more extensive branching that occurs every 8 to 12 glucose units. Starch is made of about 80% amylopectin. Amylopectin is highly branched, being formed of 2,000 to 200,000 glucose units. Its inner chains are formed of 20-24 glucose subunits. The glucose residues are linked through alpha-1,4 glycosidic linkages. -- Wikipedia [HMDB] Amylopectine C30H52O26 828.7183 828.274681836 (2R,3R,4S,5S,6R)-2-{[(2R,3S,4R,5R,6S)-6-{[(2R,3S,4R,5R,6R)-4,5-dihydroxy-6-{[(2R,3S,4R,5R,6S)-4,5,6-trihydroxy-2-(hydroxymethyl)oxan-3-yl]oxy}-3-{[(2R,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}oxan-2-yl]methoxy}-4,5-dihydroxy-2-(hydroxymethyl)oxan-3-yl]oxy}-6-(hydroxymethyl)oxane-3,4,5-triol amylopectin 9037-22-3 OC[C@H]1O[C@H](O[C@H]2[C@H](O)[C@@H](O)[C@@H](OC[C@H]3O[C@H](O[C@H]4[C@H](O)[C@@H](O)[C@@H](O)O[C@@H]4CO)[C@H](O)[C@@H](O)[C@@H]3O[C@H]3O[C@H](CO)[C@@H](O)[C@H](O)[C@H]3O)O[C@@H]2CO)[C@H](O)[C@@H](O)[C@@H]1O InChI=1S/C30H52O26/c31-1-6-11(35)13(37)19(43)28(50-6)55-24-9(4-34)52-27(21(45)16(24)40)48-5-10-25(56-29-20(44)14(38)12(36)7(2-32)51-29)17(41)22(46)30(53-10)54-23-8(3-33)49-26(47)18(42)15(23)39/h6-47H,1-5H2/t6-,7-,8-,9-,10-,11-,12-,13+,14+,15-,16-,17-,18-,19-,20-,21-,22-,23-,24-,25-,26+,27+,28-,29-,30-/m1/s1 WMGFVAGNIYUEEP-WUYNJSITSA-N belongs to the class of organic compounds known as oligosaccharides.
