unstable

Question 7

stable form of d glucose

Answer 7

ring

Answer 12

hyaluronan

Question 13

hyaluronan is a blank derivative

Answer 13

glucose

Question 14

lactose is a blank sugar because the blank end is free

Answer 14

reducing, reducing hydroxyl

sucrose is a blank sugar because the blank is not free

Answer 15

non reducing, reducing hydroxyl

Question 16

starch digestion is accomplished by blank

salivary/pancreatic alpha amylase (endoglucosidase)

Question 17

starch is broken down to these four things from saliva

Answer 17

sucrase isomaltase complex breaks down these three glycosidic bonds

Answer 18

g alpha 1,2 f ; g alpha 1,6 g ; g alpha 1,4 g

Question 19

glucoamylase complex breaks down these glycosidic bonds

Answer 19

g alpha 1,4 g (from non reducing ends)

Question 20

adding trehalose to benedicts test produces this color

Answer 20

none

Question 21

trehalase complex breaks down these bonds

Answer 21

g alpha 1,1 glucose

Question 22

lactase complex breaks down these bonds and is rate limiting in lactose digesting

Answer 22

galactose beta 1,4 g

gas that is tested for in breath that can indicate a food intolerance or IBS

Answer 23

H2

Question 24

raffinose is in blank

Answer 24

Question 29

linear chain starch, poor solubility, slowly digested

Answer 29

amylose

Question 30

branch chain starch, good solubility, fast glucose release

Answer 30

amylopectin

Question 31

amylopectin excess can cause blank which leads to type 2 diabetes

amylopectin is a starch more in

Answer 33

corn starch, potatos

Question 34

amylopectin and amylose are what we look at in the blank index

Answer 34

glycemic

Question 35

high glycemic index means highly blank
