background image Exam III Review Carbohydrates Saccharides are the smallest unit of carbohydrates (think about it being like a lego 
piece)
- Monosaccharides (1 lego piece): Glucose, galactose, and fructose - Disaccharides (2 lego pieces together) Glucose + glucose = Maltose 
Glucose + galactose = Lactose (
β-glycosidic bond; some people don’t  have the enzyme  (lactase)  to break this bond down (aka lactose  intolerance) Glucose + fructose = Sucrose - Oligosaccharide (3-10 lego pieces) - Polysaccharide ( >10 lego pieces): Stored form of glucose as Starch and 
Glycogen
Oligosaccharide (remember 3-10 units together) Raffinose  – galactose + glucose + fructose Stachyose  – galactose + galactose + glucose + fructose These two are indigestible starches (meaning we cannot breakdown, so it makes 
on its original form to the large intestine). Bacteria have the machinery to 
digest these carbohydrates, and they release gases in the process.
BEANO  – Digest the oligosaccharide before it makes to the large intestine;  Decreasing Gas production Polysaccharide: Stored form of glucose and source of energy Starch (Storage form of carbs in Plants) Starch have different names based on the alignment of the carbohydrate chain - Amylose: Straight chain of glucose units - Amylopectin: Branched chains of glucose units
background image Branching chains stabilize gels – retain water and resist seepage Glycogen (Storage form of carbs in Animals) It has more branches than starches It is important to noticed that Liver stores  glycogen  for maintaining blood  glucose homeostasis and muscle stores it for its own use Fiber – β- linkages (we cannot digest) There are two types of fiber Soluble and Insoluble Soluble Insoluble Characteristics This type of fiber forms a 
gel; think about your 
gooey oatmeal after being
cooked
Structural components. The
way the come in they go 
out. Ex: outer skin of the 
corn
Sources Jams, jellies, salad 
dressing, inexpensive ice 
creams, apples, bananas, 
oranges, carrots, barley, 
oats, kidney beans, and 
the skin and flesh of fruits 
and berries.
Wheat bran, brown rice, 
and whole grains
Health Benefits Slow gastric emptying, 
normalize blood glucose 
levels, lower blood 
cholesterol
Decreased risk for both 
colon cancer and 
diverticulitis
Fiber Overall Benefit - CHD -- by lowering cholesterol - Colon cancer -- by decreasing risk of initiation of cancer - Diabetes -- by stabilizing glucose levels - GI disfunction -- by maintaining normal GI function Best Sources: - Bran cereals, legumes, fruits, vegetables (with added benefit of 
vitamin A and C)
Recommendations:  20-30 g/day   - Insoluble to soluble ratio:  3:1
