Question | Answer |
---|---|
Bonds that form amylose | α-1-4 |
Bonds that form Amylopectin | α-1-4 and α-1-6 |
Bond in Lactose | β-1-4 |
Sugars that make up Lactose | Glucose and galactose |
Sugars that make up Sucrose | Glucose and Fructose |
Bond in Sucrose | α-1-2 |
Bond cleavage by Salivary α-amylase | intrinsic α-1-4 |
Bond cleaved by Pancreatic α-amylase | intrinsic α-1-4 |
Pancreatic α-amylase creates these | Maltose, Isomaltose, maltotriose, and limit dextrins |
4 brush boarder complexes | Glucoamylase, Sucrase-isomaltase complex, β-glycosidase complex, Trehalase |
Glucoamylase cleavage site | α-1-4 bonds starting at reducing end |
Sucrase cleaves | sucrose, maltose, and maltotriose |
Isomaltase cleaves | α-1-6 bonds in isomaltose and α-1-4 in maltose/maltotriose |
Glucosyl-ceramidase cleaves | β-bonds between glucose and galactose and ceramide from lipids |
Lactase | β-1-4 bond between glucose and galactose |
Trehalase | α-1-1 bonds in trehalose |
3 insoluble fibers | cellulose, hemicellulose, lignins |
3 Soluble fibers | pectins, mucilages, gums |
Transporter with higher affinity for fructose than glucose | GLUT-5 |
Erythrocytes has this transporter | GLUT-1 |
Glucose transporter in the liver | GLUT-2 |
GLUT that is greatly stimulated by insulin | GLUT-4 |
GLUT that is greatly stimulated by insulin, where is it? | adipose tissue, skeletal and heart muscle |
High capacity low affinity GLUT | GLUT-2 |
In barrier function cells, High affinity, low Km GLUT | GLUT-1 |
CNS GLUT | GLUT-3 |
GLUT responsible for slow transport of glucose to the brain below 80mg/dL | GLUT-1 in blood-brain barrier |
