and Exam Review
Simple sugars - ANS ✔✔contain only one or two sugar units; include monosaccharides and
disaccharides
Complex sugars - ANS ✔✔may contain 1000 or more glucose units; polysaccharides
- chiefly found in grains, veggies and fruits
Most common monosaccharides - ANS ✔✔1. Glucose
2. Fructose
3. Galactose
Glucose - ANS ✔✔- main monosaccharide in the body
- called blood sugar in bloodstream
- breakdown of starches and sucrose
- source of fuel for cells
Fructose - ANS ✔✔- fruit sugar
- in fruit, honey, and high fructose corn syrup
- converted into glucose in the *liver*
Galactose - ANS ✔✔- found in lactose
- milk/dairy products
- converted into glucose in the *liver*
Most common disasscharides - ANS ✔✔1. Sucrose
, 2. Lactose
3. Maltose
Sucrose - ANS ✔✔Glucose + fructose
- sugar (table sugar)
Lactose - ANS ✔✔Glucose + galactose
- milk products
Maltose - ANS ✔✔Glucose + Glucose
- fermentation
- alcohol production
In what form do humans store glucose? Why is this an ideal storage form? - ANS ✔✔- as
glycogen
- idea because it has more sites for enzyme production
- found in liver and muscles
What is the structure of glyocgen - ANS ✔✔similar to amylopection
What is the functional difference between fiber and starches? - ANS ✔✔- fiber is juts
undigested starch
- the body cannot break the bonds of fiber
- this prevents the small intestine from absorbing sugars that make up various fibers
What is the adequate intake (AI) recommended for fiber? - ANS ✔✔25-38 g/day (14 g/1000
kcal/day)
