CARBOHYDRATE METABOLISM 451 METABOLIC INTERRELATIONSHIPS BETWEEN CARBOHYDRATE, FAT, AND PROTEIN Connections between the metabolic systems for carbohydrates, fats, and proteins have been mentioned in a number of earlier sections. These linkages involve aspartic and glutamic acids, alanine, glycerol, and acetyl coenzyme A. They are represented schematically in Figure 18-2.

Anabolism is the opposite aspect of metabolism and refers to the synthesis of the cellular components used for other purposes than solely as sources of energy. pentospphosphatc pathway Glycerol + fatty acids.

The relationships between the metabolisms of carbohydrates, proteins, and lipides. In most cases each arrow represents a complex system of reactions. These processes are outlined individually elsewhere in the book.
