Flashcards in carb digestion Deck (17):
1

epimers

off on one carbon atom

2

isomers

same numbers and types of atoms, but not the same

3

dietary sources of carbs

startch, disaccharides, momosaccharides

4

how is glycogen similar to startch

glycogen in animal cessl, but less extensive branching in branch

5

disaccharides

sucros, trehalose, lactose

6

monosaccharides

fructose, glucose, raffinose

7

what kind of carb digestion occurs at mouth? by what?

break down oligo to mono saccharides. with salivary amylase

8

salivary amylase

alpha 1,4 glucosidase

9

two places of initial digestion

mouth and stomach

10

what is salivary amylase specific for?

internal bonds. doesn't break down alpha 1,6 glucosides or alpha 1,4 blonds at branch points

11

products of salivary amylase

oligosaccharides and some maltose

12

two compartments of small intesting carb digestion

lumen and brush border of mucosal epithelium

13

sucrose is

glucose, fructose

14

maltose

glucose, glucose

15

lactose

glucose, galactose

16

what do lower portion of SI metabolize things that are not hydrolized to?

SCFas;, lacate, H gas, methane, CO2, products which cause fluid secretion , increased intestinal motility, cramps

17

what increases rate of monos. absoprtion:

enhanced via microvili (inc surface area) and existence of specific transport proteins
