Transcript of Simple Carbohydrates

Simple Sugars Fructose, Glucose, Galactose, Mannose
Maltose, Sucrose, Lactose Simple sugars:
Carbohydrates that are quickly absorbed by the body to produce energy.
Classified as "simple"-contain only one or two units of sugar or saccharides.
Also referred to as simple carbohydrates
Found naturally in a variety of foods that we consume daily. What are Simple Sugars? what is it..? Fructose Websites: Works Cited In cooperating simple sugars
in a healthy lifestyle Lifestyle Functions
(Review) Your brain and nervous system utilize carbohydrates for energy.
In the body, carbohydrates are broken down into a molecule called glucose, which is either used for energy or stored for later use.
Simple sugars are broken down quickly, producing a rapid increase in blood sugar levels.
In contrast, complex carbohydrates take longer to break down and process in the body because of their structure. 4 Main Types Monosaccharides Glucose Fructose (fruit sugar) simple monosaccharide found in many plants absorbed into bloodstream
during digestion Maltose Sucrose Pure, dry fructose is a very sweet, white, odorless, crystalline solid and is the most water-soluble of all the sugars Fructose is the major carbohydrate present in fruit
Monosaccharide, which the body can use for energy
Does not cause blood sugar rise up tremendously FRUCTOSE Body and Fructose Sources Healthy Sources Unhealthy Sources honey, tree and vine fruits, flowers, berries, and most root vegetables. Sweet foods such as desserts, cakes,
chocolate, carbonated soft drinks, sports
drinks and so on, Fruit juice is also high in fructose. Exists in foods either as a monosaccharide (free fructose) or as a unit of a disaccharide (sucrose).
Free fructose is absorbed directly by the intestine.
The mechanism of fructose absorption in the small intestine is not completely understood.
Some evidence suggests active transport Eat plenty of vegetables, legumes and fruits•
Eat plenty of cereals, preferably wholegrain•
Limit saturated fat and moderate total fat intake•
Drink plenty of water •Limit your alcohol intake if you choose to drink•
Consume only moderate amounts of sugars and foods containing added sugars•
Prevent weight gain
Be physically active and eat according to your energy needs a disaccharide composed of two glucose residues
fundamental structural unit of glycogen
and starch
A white crystalline sugar formed during
the digestion of starch. Maltose what is it..? MALTOSE Maltose and the Body Sources Also known as malt sugar, maltose is formed by uniting two units of glucose that provide the first link in a process that eventually results in the creation of starch. (malt sugar) Not a substance that should be consumed as a separate sweetener in the same manner as table sugar

Serves as an excellent additive to many different types of packaged foods, including non-alcoholic beverages. Healthy Germinating grains, pistachios, sweet
potatoes and various fruits, including
kiwis, dates, cherries and blueberries beer, high-maltose corn syrup, candies, baked goods and soft drinks Unhealthy Maltose or malt sugar, is formed from two units of glucose. Maltose is not common in food, but can be formed from the digestion of starch, and is heavy in the sugar in malt, the juice of barley and other grains.
Serves as an important intermediate in the digestion of starch. When you digest starch, your body converts it to glucose to serve as a source of energy. Maltose can form from this starch when it is broken down, and it in turn can be readily digested into the glucose molecules and the preferred fuel of the brain and nervous system.
Through a process called fermentation, glucose, maltose and other sugars are converted to ethanol by yeast cells in the absence of oxygen. Muscle cells convert glucose into lactic acid to get energy.
Failure to break down maltose in the intestine will lead to diarrhea, excessive gases, and other symptoms. nonreducing crystalline disaccharide made up of glucose and fructose
found in many plants but extracted as ordinary sugar
used as a sweetener or preservative (table sugar) Sucrose what is it..? Sucrose and the body Sources SUCROSE Refined sugar was a luxury before the 18th century.
It became popular in 18th century, then graduated
to becoming a necessary food in the 19th century.
Sugar is an essential food ingredient that unleashed major economic and social changes. Eventually,table sugar became sufficiently cheap and common enough to influence standard cuisine
and flavored drinks. Sucrose forms a major element in confectionery and desserts.
Cooks use it for sweetening — its fructose component, which has almost double the sweetness of glucose, makes sucrose distinctively sweet in comparison to other carbohydrate foods. Healthy Unhealthy fruits, root vegetables (carrots,
onions), sugar beets, sugar cane sweets, cakes, juice crystals, pop, milkshakes, biscuits and fast food . Sucrose is a rich source of energy for your cells. While sucrose helps provide you with energy it's easy to over consume it, which can lead to change in blood sugar levels and excess storage of fat. When you consume sucrose, before you can use it for any cellular purposes, you have to digest it. The sucrose molecule is too large for your intestine to absorb whole. Instead, you use an enzyme in the small intestine called sucrase to break sucrose into its constituent glucose and fructose molecules. These are small enough that you can absorb them into the bloodstream.
One of the important uses of carbs such as sucrose is to provide for immediate energy. "Sucrose PlayV2('en/US/df/dfsgssddsdsgstd5hn');playV2('en/UK/df/dfsgssddsdsgstd5hn')."TheFreeDictionary.com. N.p., n.d. Web. 14 Oct. 2012. <http://medical-dictionary.thefreedictionary.com/sucrose>.

Any of a class of sugars whose molecules contain two monosaccharide residues. mon·o·sac·cha·ride
Any of the class of sugars (e.g., glucose) that cannot be hydrolyzed to give a simpler sugar. simple monosaccharide found in plants
absorbed directly into the bloodstream during digestion
cells use it as the primary source of energy and a metabolic intermediate. Glucose what is it..? Glucose and the Body Sources GLUCOSE The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. The body's homeostatic mechanism keeps blood glucose levels within a narrow range. It is composed of several interacting systems, of which hormone regulation is the most important.

There are two types of mutually antagonistic metabolic hormones affecting blood glucose levels:

catabolic hormones (such as glucagon, cortisol and catecholamines) which increase blood glucose;
and one anabolic hormone (insulin), which decreases blood glucose. Healthy Unhealthy squash, oranges, molasses, celery junk food, sweets, candy, fast food Galactose Found in animals and humans
