Intestinal Sucrase Activity

Intestinal sucrase activity of the rat varies with the age, but not the sex, of the animal. Sucrase activity of rats 23 days of age was approximately two-thirds that of adults.Sucrase activity of adult rats was significantly decreased by several days of fasting. The decrease was rapid during the first 2 to 4 days of the fast, but became negligible thereafter.Diets containing large (70%) amounts of sucrose, galactose, melizitose, or α-methyl-D-glucoside produced highly significant increases in intestinal sucrase levels (compared with a carbohydrate-free, high-casein control diet) when fed ad libitum for 24 hours to adult male rats previously fasted for 3 days. Similar diets containing fructose, fructose plus glucose in equimolar amounts, or maltose significantly increased sucrase activity, but diets containing glucose, mannose, xylose, or lactose were not stimulatory. A 70% raffinose diet significantly decreased sucrase activity. Normal male rats which were fed the 70% sucrose diet for 4 weeks had sucrase activities similar to those of controls fed Purina fox checkers, but animals fed the carbohydrate-free, high-casein diet for 1 day or longer had sucrase activities significantly lower than those of controls. The significance of these observations in regard to enzyme "adaptation" is discussed.

Intestinal Sucrase Activity

Increased efficiency of nutrient utilization can potentially be gained with increased starch digestion in the small intestine in ruminants. However, ruminants have quantitative limits in the extent of starch disappearance in the small intestine. The objective is to explore the nutritional and physiological constraints that contribute to limitations of carbohydrate assimilation in the ruminant small intestine. Altered digesta composition and passage rate in the small intestine, insufficient pancreatic α-amylase and/or small intestinal carbohydrase activity, and reduced glucose absorption could all be potentially limiting factors of intestinal starch assimilation. The absence of intestinal sucrase activity in ruminants may be related to quantitative limits in small intestinal starch hydrolysis. Multiple sequence alignment of the sucrase-isomaltase complex gives insight into potential molecular mechanisms that may be associated with the absence of intestinal sucrase activity, reduced capacity for intestinal starch digestion, and limitations in the efficiency of feed utilization in cattle and sheep. Future research efforts in these areas will aid in our understanding of small intestinal starch digestion and glucose absorption to optimize feeding strategies for increased meat and milk production efficiency.

Elephant foot yam (Amorphophallus paeoniifolius (Dennst.) Nicolson syn. Amorphophallus campanulatus) is a tuber vegetable used as an ingredient in ayurvedic preparations for various ailments. The present investigation deals with the effect of elephant foot yam extract on intestinal and renal disaccharidases in normal rats and streptozotocin induced diabetic rats. The specific activities of maltase, sucrase and lactase were measured in control and starch fed diabetic (SFD), elephant foot yam extract at 0.1% fed diabetic (YFD0.1), elephant foot yam extract at 0.25% fed diabetic (YFD0.25) and aminoguanidine fed diabetic (AFD) groups at the end of experimental period. Intestinal maltase, sucrase and lactase activities were high in SFD group compared to control, YFD0.1, YFD0.25 and AFD groups. Amelioration of intestinal maltase activities by 18% 26% and 48% was observed in YFD0.1, YFD0.25 and AFD groups respectively when compared to SFD group. Intestinal sucrase activity was ameliorated in YFD0.1, YFD0.25 and AFD groups to about 28%, 45% and 56% respectively. Lactase activity of intestine was improved by 36%, 52% and 64% in YFD0.1, YFD0.25 and AFD groups respectively. On the contrary, specific activities of renal maltase, sucrase and lactase were decreased in SFD group compared to control groups. Supplementation of elephant foot yam extract in diet significantly ameliorated renal disachharidases activities in YFD0.1 and YFD0.25 groups. The results demonstrate the potential use of elephant foot yam for the management of diabetes.
