DIGESTION AND ABSORPTION 2 Flashcards
monosaccharides
glucose, fructose, galactose
dextrose, has a 6 carbon ring structure
converted to glycogen, lactic acid
glucose
6 carbon ring structrure
converted to glucose in liver or stored as glycogen
galactose
used in genetic material
ribose
2 mol of glucose
production of alcohol
maltose
glucose + fructose
table sugar
sucrose
glucose + galactose
primary sugar found in milk
lactose
aplha 1,4 glucosidic bond
stains blue in iodine
amylose
alpha 1,6 glucosidic bond
stains reddish to brown in iodine
amylopectin
animal storage of polysaccharide
storage form of glucose in humab body
glycogen
initially digests starch, dextrins, isomaltose, maltose, lactose, sucrose celulose in the mouth
alpha salivary amylase
acts on sucrose breaking it to become glucose and fructose
isomaltase
hydrolyzed to maltose which is then hydrolyzed 2 molecules of glucose
maltase
acts on lactose to become glucose and galactose
lactase
absence of lactase
lactase splits lactose into Glu and Gal because of absense of lactase
lactose cant be broken down goes to directly large intestine
normal flora would ferment the lactose
lactose intolerance
