The word carbohydrate arose because molecular formulas of these compounds can be expressed as hydrates of carbons which yield a basic carbohydrate empiric formula of (CH2O)n. Carbohydrates consist mainly of the combination of two chemistry functional groups: the carbonyl and the hydroxyl group. Carbohydrates exist in different forms such as monosaccharides, oligosaccharides, and polysaccharides.



Oligosaccharides contain at least two monosaccharide units. Oligosaccharides may be referred to as disaccharides or trisaccharides depending on how many units of monosaccharides the compound contains. Maltose and sucrose (table sugar) are considered disaccharides.

Dietary carbohydrate digestion occurs mainly in the mouth and small intestine. During mastication (chewing) the salivary glands secrete the enzyme alpha-amylase which is referred to as ptyalin. Alpha-amylase briefly acts on dietary carbohydrates in the mouth to hydrolyze starch into simple sugars such as glucose. In fact, if you chew on a carbohydrate long enough you may taste sugar. This is a result of salivary amylase hydrolyzing the carbohydrate into a simpler sugar.

Once the chewed food has been swallowed into the stomach, carbohydrate digestion halts temporarily. This occurs because alpha-amylase is inactivated by the high acidic environment of the stomach. However, carbohydrate digestion will resume once the chyme (food mass and gastric juices of the stomach) enters the small intestine.

Now that we have a good understanding of what a carbohydrate is and the importance of the carbohydrate in the body, maybe an extreme low carb diet isn’t the answer for weight loss. Extreme diets whether they are low carb or high protein can put the body to the test. Carbohydrates may be a necessary evil, but the body relies heavily on carbohydrates for energy. Instead of testing one’s will power, using a weight loss supplement called a carb blocker may be a better option.

Phaseolus vulgaris is the active ingredient in carb blockers that comes from the white kidney bean. Phaseolus vulgaris interferes with the pancreas’ ability to secrete the enzyme alpha-amylase. Subsequent studies do prove that Phaseolus vulgaris does in fact inhibit the enzyme alpha-amylase.
