    多糖

    凡能水解成多个单糖分子或其衍生物的糖为多糖。它是由二十个至数万个单糖分子缩合、脱水而成的大分子化合物。多糖可以由一种单糖组成，如淀粉、纤维素等称为同聚多糖；也可以由不同单糖或其衍生物缩合而成，例如半纤维素，则被称为杂聚多糖。

    自然界中，植物、动物和微生物都含有丰富的多糖。除了以游离形式存在外，多糖也常与蛋白质结合形成复合物。植物多糖的共同特点是天然性、保健价值及独特的水溶性胶体特性，这赋予食品较高的营养价值、稳定的组织结构以及优良的外观和口感，并延长了其货架期。

    天然植物多糖对人体更为安全，吸收率更高。例如魔芋中的葡甘聚糖，这是一种极好的水溶性膳食纤维，具有饱腹感、降血脂、降血糖及通便等保健功能。尽管植物多糖本身不提供热量，但它对高热量、高脂肪和高蛋白的饮食结构有平衡营养的作用。

    因此，亲水性的植物多糖常被称为植物胶，它们能够为食品生产加工提供增稠剂、凝胶剂、成膜剂及乳化剂等多种稳定剂。有效开发和利用植物多糖将有助于提升人类的生活质量、改善健康水平，并丰富食物资源，从而创造更多的经济价值。

    淀粉是储存在植物体内的多糖，由直链淀粉和支链淀粉两种成分构成。在淀粉颗粒中，直链淀粉占比20～28%，其余为支链淀粉。直链淀粉由约250至300个D-葡萄糖分子通过α 1,4糖苷键连接而成，并卷曲成螺旋结构，具有一个非还原性末端和一个还原性末端，其分子量差异很大，从数千到150,000不等。直链淀粉遇碘呈蓝色反应，这是由于螺旋内部为分子碘占据所致。

    支链淀粉由24至30个D-葡萄糖分子通过α 1,4和α 1,6糖苷键连接而成，形成类似灌木丛的结构。动物消化道中的α淀粉酶（存在于唾液及胰液中）可以随机作用于α 1,4糖苷键，将直链淀粉水解成麦芽糖和葡萄糖；植物中的β淀粉酶则在直链淀粉非还原性末端起作用，生成麦芽糖。支链淀粉同样可被α和β淀粉酶作用，但靠近分枝点的α 1,4和α 1,6糖苷键不被这些酶水解，在α淀粉酶及1,6葡萄糖苷酶共同作用下，支链淀粉完全水解为葡萄糖和麦芽糖。

    琼脂糖是琼脂的重要组成部分，由D-半乳糖与3,6脱水半乳糖构成的单位重复缩合而成。琼脂糖在沸水中大量溶解，但当温度降至40℃以下时则成不溶性凝胶。这种琼脂糖凝胶常用作层析的支持体，通过氢键将半乳多糖链交联形成，因此在过于酸碱环境中不稳定。
