They form starch
What are amylose and amylopectin?
alpha-amino carboxylic acid
What is an amino acid?
process that makes fats accessible to water-soluble lipases
What is emulsification?
requires bacterial digestion for breakdown and absorption
What is dietary fiber?
the 5 key receptors associated with nausea and vomiting
What are muscarinic (M1), dopaminergic (D2), histaminergic (H1), serotonin (5-HT), and substance P (NK1) receptors?
dietary disaccharides
What are sucrose and fructose?
acid causes autocatalytic conversion to the active form
What is pepsinogen?
Secreted by Chief cells
Breaks proteins into chunks at neutral AA's
converts triglycerides to diacylglycerides in the stomach
What is gastric lipase?
an enzyme that cleaves and activates all pancreatic peptidases
the 5 common triggers for nausea and vomiting
breaks down internal α-1,4 starch bonds
What is amylase? (salivary and pancreatic)
it cleaves tyrpsinogen
What is enterokinase?
What are lipase, phospholipase A2, and cholesterol esterase?
captures cholesterol, vasodilation, anti-inflammatory, anti-oxidation, anti-infectious, antithrombotic, antiapoptotic, and improves glucose metabolism
Why are HDL chylomicron remnants good for you?
Hafiane, Anouar & Genest, Jacques. (2013). HDL, Atherosclerosis, and Emerging Therapies. Cholesterol. 2013. 891403. 10.1155/2013/891403.
similar MOA as phenothiazines, is anti-emetic at higher doses
What is metoclopramide?
From Plumb: In the CNS, metoclopramide antagonizes dopamine D2 receptors, is a weak inhibitor of serotonin 5-HT3 receptors, and is an agonist of serotonin 5-HT4 receptors.
3 brush border carbohydrate hydrolases
What are sucrase, isomaltase, and glucoamylase? (+ lactase)
the three pancreatic endopeptidases
What are trypsin, chymotrypsin, and elastase?
trypsin cleaves proteins at basic AA's, so the C-terminal of its product is basic
the other two cleave at neutral AA's
Formed in the intestinal lumen by bile acids and lipids
What are micelles?
These speed lipid absorption and are essential for fat-soluble vitamin absorption
fats that enter the portal circulation directly
What are medium-chain triglyerides?
Wikipedia: A medium-chain triglyceride (MCT) is a triglyceride with two or three fatty acids having an aliphatic tail of 6–12 carbon atoms, i.e. a medium-chain fatty acid (MCFA). Rich food sources for commercial extraction of MCTs include palm kernel oil and coconut oil.
More effective than maropitant at reducing nausea behaviors in dogs following cisplatin therapy
What is ondansetron?
Kenward H, Elliott J, Lee T, Pelligand L. Anti-nausea effects and pharmacokinetics of ondansetron, maropitant and metoclopramide in a low-dose cisplatin model of nausea and vomiting in the dog: a blinded crossover study. BMC Vet Res. 2017 Aug 16;13(1):244. doi: 10.1186/s12917-017-1156-7. PMID: 28814338; PMCID: PMC5559813.
transporter required for absorption of glucose and galactose
What is SGLT1?
the two ectopeptidases
What are carboxypeptidase A and B?
B works at basic carboxy end after trypsin
A works at neutral carboxy end after elastase and chymotrypsin
Brush border/membrane/cytosolic oligopeptidases finish the job
formed in the enterocyte but does not enter the portal circulation following exocytosis
What are chylomicrons?
a protease inhibitor that prevents activation of trypsin within the pancreas
What is SPINK1 (serine protease inhibitor Kazal type 1)?
more effective than ondansetron at preventing nausea behaviors in dogs following premedication with hydromorphone, acepromazine, and glycopyrrolate
What is maropitant?
