In order for mucles to provide energy, what has to be present?
What happens when we don't get enough carbs?
We starve our body and too many ketones are produced. Ketosis results
If a person has fruity breath, you might suspect that they are suffering from.....

Give an example of some of the natural sugars

What are polysaccharides?
Complex carbs; sugars containing over 12 carbon atoms

What is lipogenisis?
The process of converting glucose to fats
What is hyperglycemia?
Elevated blood sugar
What is hypoglycemia?
Low blood sugar
What is phenylketonuria?
A genetic disorder characterized by the inability to metabolize the amino acid phenylalanine
Carbs are made by all plants from what?
carbon, hydrogen, and oxygen
These type of sugars contribute to the palatability of a food because of their sweetness?
MOno and dissacharides
Name the monosaccharides of greatest significance in the foods and body metabolism are?
Glucose, fructose, and galactose
Which monosaccharide is the sweetest?
what is another name for glucose?
Dextrose or corn syrup. Naturally abundant in many fruits.
The principal product formed by the digestion of dissacharides and polysacharides. It provides energy for cells via the bloodstream.
Another name for fructose?
Levulose. Found naturally in honey anf fruits. A product of the digestion of sucrose
Product of lactose digestion (milk sugar). Legumes can also contain lactose
Sugar alcohols?

What does sugar alcohol do?
Adds about the same amount of sweetness as glucose and the same amount of calories. Their advantage is that they do not contribute to tooth decay

Because they contribute to body function only after they have been digested
