Digestion Flashcards
______digests glycogen and starch, yielding branched and unbranched oligosaccharides called______
Salivary a-amylase
Dextrins
T/F no lipid digestion happens on oral cavity
T
But lingual lipase originates at the back of the tongue
T/F proteins are not changed in the oral cavity
Protein
In the stomach, ____ and ______ digest TAG, contain short and medium-chain fatty acids
Acid-stable emzymes important in neonates
Gastric and lingual lipase
In the sromach, Pepsinogen is converted to pepsin by _____ screted by _____
HCl
Parietal cells
Secretes pepsinogen
Chief cells
Enzymes in the small intestine for carb digestion
Pacreatic amylase
Disaccharidases
Results in disaccharidases
Pancreatic alpha amylase
Majority of carb digestion occurs where
Duodenum and upper jejunum
Emulsifies dietary lipids in small intestines
Bile salts
Small intestine
Digests TAG in to monoacyglycerols and 2 FA
Pancreatic lipase
Small intestine
Digests cholesterol esters into cholesterol and FA
Cholesteryl ester hydrolase
Pancreatic lipase requires —— to function
Colipase
Cellulose is mot digested because
It has Beta glycosidic bonds
Cannot be digested by alpha glycosidases
Transpoter used im facilitated diffusion of fructose
Glut 5
Transporter of glucose, galactose, fructose into portal circulation
Glut2
Transporter if glucose and galactose
SGLT
Lipid form from intestinal cell to lymphatics
Chylomicron
Lipid form
Intestinal lumen to cell
Micelle
Free AAs are taken to portal circulation via
Facilitated diffusion
Free AA are absorbed via
Secondary active transport
Di and tri peptides are absorbed via
H linked transport
Located in burch border
Releases free AA from dipeptides and oligopeptides
Aminopeptidases
