#1
Front (Question)

wat doen proteasen?

Back (Answer)

Proteasen verbreken de peptidebindingen tussen twee aminozuren door middel van het toevoegen van een watermolecuul: hydrolyse. Hydrolyse van eiwitten wordt proteolyse genoemd.

#2
Front (Question)

hoe wordt de hydrolyse van een eiwit genoemd?

Back (Answer)

proteolyse

#3
Front (Question)

wat doet protease?

Back (Answer)

cuts the peptide bond

#4
Front (Question)

aminopeptidase cuts from

Back (Answer)

H2N

#5
Front (Question)

carboxypeptidase cuts from the

Back (Answer)

COOH

#6
Front (Question)

Chymosin (rennin) is added to milk during production of cheese and does two things:

Back (Answer)

• coagulation of milk protein • contributes to flavour and texture

#7
Front (Question)

other applicaition of proteases

Back (Answer)

• beer • baking • meat • protein hydrolysis/ modification

#8
Front (Question)

why is chymosin the preferred enzyme for cheese production?

Back (Answer)

Chymosin specifically cleaves κ-casein into para- κ-casein

#9
Front (Question)

what does lipase do?

Back (Answer)

converts triglyceride in –> glyceride + fatty acids

#10
Front (Question)

where is lipase active?

Back (Answer)

oil/ water interface

#11
Front (Question)

what does lipoxygenase do?

Back (Answer)

conversion of fatty acids with a cis, cis, 1-4-pentadiene system into instable hydroperoxides

#12
Front (Question)

what are the differences between lipas and lipoxygenase?

Back (Answer)

• Hydrolase versus oxidoreductase • Cleaving at glycerol-fatty acid ester-bond versus O2 addition to fatty acid chain forming instable hydroperoxides.
