L-arabinose, also known as aldose and pectinose, is a kind of aldose with the chemical formula C5H10O5. In nature, L-arabinose rarely exists in the form of monosaccharides, and is usually combined with other monosaccharides, and exists in the form of heteropolysaccharides in gums, hemicelluloses, pectic acid, bacterial polysaccharides and certain glycosides. Its stability to heat and acid is high.
L-arabinose, as a low-calorie sweetener, is widely found in the skins of fruits and whole grains. Because it can inhibit the activity of invertase in the human intestines, it has the effect of inhibiting the absorption of sucrose; in addition, L-arab Sugar can also inhibit body fat accumulation, so it can be used to prevent and treat diseases such as obesity, high blood pressure, and hyperlipidemia. In Japan, the Ministry of Health and Welfare listed L-arabinose as a "special health food additive for blood sugar regulation"; the American Medical Association listed L-arabinose as an "anti-obesity nutritional supplement or over-the-counter drug"; after that, the Chinese Ministry of Health announced in 2008 The formal approval of L-arabinose as a new resource food confirms its important position in the field of functional sugars.

1. Inhibit metabolism and absorption
The most representative physiological role of L-arabinose is to selectively affect the invertase in the small intestine, thereby inhibiting the absorption of sucrose. According to reports, adding 3.5% L-arabinose to sucrose can inhibit the absorption of 60-70% sucrose, and at the same time reduce the blood sugar level by about 50%.
2. Inhibit blood sugar and fat
As a low-calorie sugar, L-arabinose inhibits the increase in blood sugar caused by the intake of sucrose, so it can inhibit obesity, prevent and treat diseases related to hyperglycemia.
3. Prevent constipation
The results of a Japanese study show that women who are prone to constipation add sucrose with 3% L-arabinose to black tea and other beverages for continuous consumption, and the number of bowel movements per week has increased significantly. According to the experiment of Sanhe Starch Co., Ltd., the intake of sucrose supplemented with 5% arabinose can also effectively promote the growth of Bifidobacterium. L-arabinose itself is a sugar that is difficult to be absorbed by the digestive tract, and the unused part in the body can be excreted in the urine.
4. Influence on skeletal muscle composition
A study in Japan in 2005 demonstrated the effect of L-arabinose on energy expenditure and muscle fiber composition. Obese rats were fed a diet containing 20% sucrose (group C) and 20 with 1.5% L-arabinose. % Sucrose diet (group A) for 21 weeks. The abdominal adipose tissue weight and cell size of rats in group C increased significantly, while the fat weight and cell size of rats in group A were significantly suppressed. L-arabinose significantly inhibited the increase in blood sugar 2 hours after the administration of glucose. When evaluated by respiratory quotient, the percentage of energy consumed by fat in group A rats increased by 12.8%. The number of type I fibers in the rectus abdominis muscle increased significantly. Like other skeletal muscles, the rectus abdominis muscle is composed of type I and type II muscle fibers. These results suggest that L-arabinose has the effect of changing the composition of skeletal muscle fibers, and influences the growth of abdominal adipose tissue by controlling glycolysis to sugar oxidation. This change in the ratio of muscle fibers may have the effect of improving type 2 diabetes.
1. The application of L-arabinose in bakery products.
L-arabinose has a stable molecular structure and is not decomposed at high temperatures, so it can be used in bakery products. s color.
2. The application of L-arabinose in beverages.
With the improvement of people's living standards, consumers' health awareness has gradually strengthened, and the structure of people's beverages has also undergone significant changes. The market for high-calorie beverages has declined year by year. Protein beverages, fruit and vegetable juice beverages and other nutritional, health-care, and functional beverages have gradually become the mainstream of the market. The addition of L-arabinose products in various beverages is in line with people's needs.
3. The application of L-arabinose in biomedicine.
Nucleoside analogues derived from L-arabinose have the characteristics of being able to specifically inhibit hepatotropic DNA virus, not affecting DNA polymerase and mitochondrial function, high selectivity, and low toxicity. They are widely used and have broad market prospects.
4. The application of L-arabinose in other fields.
Using L-arabinose as raw material, through hydrogenation synthesis reaction, a rare sugar alcohol-arabitol can be prepared, which can be used in microbial fermentation and genetic improvement experiments; it can also be used to synthesize anti-AIDS, anti-virus, and anti-cancer drugs An important pharmaceutical intermediate-L-ribose; it can also produce arabinose-reactive flavor that can produce a soft and rich aroma.
