Maltose (/ˈmɔːltoʊs/ or /ˈmɔːltoʊz/), also known as maltobiose or malt sugar, is a disaccharide formed from two units of glucose joined with an α(1→4) bond. Maltose is the two-unit member of the amylose homologous series, the key structural motif of starch.

Maltose consists of two molecules of glucose that are linked by an α-(1,4′) glycosidic bond. Maltose results from the enzymatic hydrolysis of amylose, a homopolysaccharide (Section 28.9), by the enzyme amylase. Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond.

In maltose, two glucose units are joined by an α-1,4 glycosidic linkage, as stated earlier. Maltose comes from the hydrolysis of starch and is in turn hydrolyzed to glucose by maltase. Sucrase, lactase, and maltase are located on the outer surfaces of epithelial cells lining the small intestine (Figure 11.12).

It is useful in making hard candies and an inexpensive sweetener. Summary: Maltose is found in starchy grains, vegetables and fruits. It is useful as a low-cost sugar source in the form of high-maltose corn syrup.

So, maltose is a disaccharide that is made up of two glucose units. It has a slightly sweet taste, but it’s most important function is in digestion. Since most carbohydrates are in a form that cannot be absorbed, it is important for these carbohydrates to be broken into smaller pieces.

Maltose undergoes mutarotation at its hemiacetal anomeric center. Recall that the process occurs via an open-chain structure containing an aldehyde. The free aldehyde formed by ring opening can react with Fehling’s solution, so maltose is a reducing sugar.

Carbohydrate Structure Maltose (or malt sugar) is an intermediate in the intestinal digestion (i.e., hydrolysis) of glycogen and starch, and is found in germinating grains (and other plants and vegetables). It consists of two molecules of glucose in an α-(1,4) glycosidic linkage.

Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form. Glucose is naturally occurring and is found in fruits and other parts of plants in its free state.

A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours indicates diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) indicates prediabetes.

Less than 140 mg/dL (7.8 mmol/L) is normal. 140 to 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) is diagnosed as prediabetes. 200 mg/dL (11.1 mmol/L) or higher after two hours suggests diabetes.

What Are Normal Blood Sugar Levels? They’re less than 100 mg/dL after not eating (fasting) for at least 8 hours. And they’re less than 140 mg/dL 2 hours after eating. During the day, levels tend to be at their lowest just before meals.

What is high blood sugar? Blood glucose is commonly considered too high if it is higher than 130 mg/dl before a meal or higher than 180 mg/dl two hours after the first bite of a meal. However, most of the signs and symptoms of high blood glucose don’t appear until the blood glucose level is higher than 250 mg/dl.

Persistently high blood sugar usually means you have diabetes. If HbA1c is more than 48 mmol/mol or fasting blood glucose is more than 11 mmol/L, your blood sugar is high. For most people without diabetes, normal blood sugar levels are: between 4 and to 6 mmol/L before meals.

For most people with diabetes, fruits (including bananas) are a healthy choice. Although, if you’re following a low carb diet to manage your diabetes, even a small banana contains around 22 grams of carbs, which may be too much for your eating plan.

If you have diabetes, eating a variety of fruits — including oranges — is good for your health. Whole oranges may keep your blood sugar levels steady due to their low GI, fiber content, and other nutrients.

Worst Fruit for Weight Loss

• Bananas. Bananas are a great replacement for a pre-workout energy bar which is why you often see professional tennis players snacking on them in between games.
• Mango. Mangos are one of the most commonly consumed fruits in the world.
• Grapes.
• Pomegranate.
• Apples.
• Blueberries.
• Watermelon.
• Lemon.

The 12 most dangerous fruits and vegetables are:

• Apples, peaches, nectarines, strawberries, grapes, celery, spinach, sweet bell peppers, cucumbers, cherry tomatoes, imported snap peas and potatoes.
• On a better note, the EWG also produced a list of “Clean Fruit and Vegetables”

Here are 20 foods that are generally unhealthy — although most people can eat them in moderation on special occasions without any permanent damage to their health.

1. Sugary drinks.
2. Most pizzas.
3. White bread.
4. Most fruit juices.
5. Sweetened breakfast cereals.
6. Fried, grilled, or broiled food.
7. Pastries, cookies, and cakes.
