The research outlined in this proposal involves two main areas of carbohydrate (sugar) chemistry. We plan to investigate the fundamental aspects of the biological reactions of carbohydrates and how they deviate from the corresponding reactions in water. Organisms are complex entities whose very existence depends on the ability to metabolize (breakdown) various dietary nutrients. Two distinct phases of metabolism exist: (1) energy-yielding catabolic processes that involve the degradation of complex food sources such as carbohydrates, proteins, and fats to produce simpler molecules; and (2) anabolism, that phase that is concerned with natural processes in which simple components, such as glucose are used to form more complex molecules that are required for the growth and survival of an organism. These two types of metabolic pathways employ enzymes that are either specific for degradation-type reactions, or that function in reactions which lead to the assembly of complex molecules.

该提案中概述的研究涉及碳水化合物（糖）化学的两个主要领域。我们计划研究碳水化合物生物反应的基本方面，以及它们如何偏离水中的相应反应。生物是复杂的实体，其存在的存在取决于代谢（分解）各种饮食营养素的能力。存在两个不同的代谢阶段：（1）能量赋予分解代谢过程，涉及复杂食品源的降解，例如碳水化合物，蛋白质和脂肪，以产生更简单的分子； （2）合成代谢，与自然过程有关的阶段，其中简单成分（例如葡萄糖）用于形成有机体生长和生存所需的更复杂的分子。这两种类型的代谢途径采用特定于降解型反应的酶，或者在导致复杂分子组装的反应中的功能。
