Carbohdrates are	major food source and energy supply of the body
what is glycogen?	a polysaccharide that is the principal storage form of glucose
Glycogen is stored in ?	liver
Glycogenesis-	converstion of glucose to glycogen for storage
Gluconeogenesis	formation of glucose-6-phophate from noncarbohydrate sources
Glycogen is used up in about ?	24-48 hours
Glucagon will?	Increase blood glucose by stimulating glycogenolysis and gluconegenesis
Glycogenolysis ?	breakdown of glycogen to glucose for use as enegry
Monosacchardies	simple sugars that cannot be hydrolgyzed to a simpler form EX- glucose, fructose, galactose
Disaccharides	two monosacharides jointed by a glycosidc linkage ex. Maltose, Lactose, sucrose
. Maltose	two glucose molecucles
Lactose	milk- glucose, galactose
sucrose	table sugar- glucose, fructose
Disaccharides must be converted to	monosaccharides hydrolyzed by enzyme from small intestines
Polysaccharides	chaining 2 to 10 sugar units Ex. Starch- long branching chain of glucose molecules
starch Digestion- being in ?	by salivary Amylase to breakdown to Dextrins, Maltose , pancreatic sercations
Stach is broken down to	maltose then to glucose
Nonredcuing carbohydrates do not	have en active ketone or aldehyde group
Salivary and amylase and pancreatic amylase are responsible for the digestion of these nonabsorbable polymers ?	Nonredcuing carbohydrates
When disaccharides are converted to monosaccharides	absorbed by the gut and transported to the liver by the hepatic portal venous blood supply
