Chapter 4 (Section A) Flashcards
A simple sugar made up of 6 carbons, 12 hydrogens, and 6 oxygens that provide energy for the body
glucose
Organic molecules used primarily for energy
carbohydrates
Carbs protect ______ _____ from being catabolized during exercise and they provide the main energy source for the _________ and __________ ___________.
muscle mass; brain and nervous system
One glucose molecule can produce how many molecules of ATP?
30
two types of carbohydrates
simple and complex
The four different types of carbohydrates based on the number of sugar units:
monosaccharides, disaccharides, oligosaccarides, and polysaccharides
consist of one sugar unit
monosaccharide
monosaccharide examples (4)
glucose, galactose, mannose, and fructose
consist of two sugar units
disaccharides
Disaccharide examples and composition
sucrose (one glucose and one fructose), and lactose (one glucose and one galactose)
a simple sugar found mostly in fruits
fructose
the energy source of plants; a polysaccharide consisting of multiple molecules of bonded glucose
starch
a polymer of fructose molecules found in some fruits, legumes, and vegetables
fructan
What explains the slower rise in blood sugar after eating fructose
fructose has to be further broken down by the liver into glucose before being used by most cells in the body
two main types of complex carbohydrate
oligosaccharises and polysaccharides
two types of simple carbohydrates
mono and di saccharides
complex carb with 3 to 10 sub-units of sugar; two examples
oligosaccharides; raffinose and statchyose
complex cabs that have 10 or more monosaccharide sub-units linked together; three examples
polysaccharides; amylose, amylopectin, and glycogen
composed of amylopectin and amylose
starch
special type of complex carb that is not digested and not absorbed in the small intestine (two terms)
fiber or non starchy roughage
Eight examples of fiber
cellulose, hemicellulose, pectin, fructans, beta-glucans, and a variety of gums, mucilage, and algal polysaccharides
Two functions of fiber
promotes intestinal function and aids in the absorption of nutrients into the bloodstream.
Two types of fiber
soluble and insoluble
type of fiber that dissolves in fluids in the stomach to form a thick gel like substance
soluble fiber
