描述：

Sucrose

Cell Culture Reagent
Crystalline

Structure:


 

Molecular Formula: C₁₂H₂₂O₁₁
 

Synonyms: Beet sugar; Cane sugar; b-D-Fructofuranosyl-a-D-glucopyranoside; D-(+)-Saccharose; Sugar; a-D-Glucopyranosyl-b-D-fructofuranoside

Physical Appearance: White crystalline powder

Solubility: Soluble in water (1 g/0.5 ml @ 25°C; 1 g/0.2 ml boiling water), ethanol (1 g/170 ml) or methanol (1 g/100 ml); moderately soluble in glycerol or pyridine.¹

Note:¹ Sucrose is hydrolyzed to glucose and fructose by dilute acids and by invertase, a yeast enzyme. Upon hydrolysis the optical rotation falls and is negative when the hydrolysis is complete. The mixture of glucose and fructose is known as "invert sugar."

Description: A simple carbohydrate. Its use in density gradients has been described.^4,8,15,17

Physiological Impact of Dietary Carbohydrate Source: Diets which are high in simple carbohydrates, e.g., sucrose, can cause fatty liver^2,18 and Hepatic lipid levels can increase up to 6 fold over normal controls.² Serum triglycerides are also increased. Substitution of corn starch for sucrose can reverse these effects.¹⁴ Intestinal flora are also affected by the simple vs. complex carbohydrate ratio in the diet.^5,19,20

The toxicity of some drugs is markedly affected by the simple/complex carbohydrate ratio of the diets used in the study.^6,9,12,13Intestinal secretion of lipids and lipoproteins is also effected by the simple/complex ratio of the diet.¹⁶ For these reasons, Bacon, et al.², concludes that "The AIN-76A Diet is not suitable for toxicological studies which depend on normal hepatocellular structure." In a few cases, such as in riboflavin deficient diets, sucrose is preferred over corn starch due to its interactions in the gut to decrease intestinal synthesis of riboflavin, whereas corn starch has the opposite effect.³
