add HCl n heat in to hydrolise starch.....then add NaHCO3 to neutrilize HCl added befre..then perfrm the normal reducing sugar test....



umm fungal amylase is protien?

the starch can be hydrolysed by the amylase no ? than why do we need to that :/ all so confusing

soo for fungal amylase were suppose to do protein test ryt?

dude cuz it may be denatured..or it may no hyrdolys it.... plus v also ve to test tht....

soo for fungal amylase were suppose to do protein test ryt?

yup...

thank u so oooooooooooooooo much u r a life saver

i think we r getting a monocot stem..not sure...but dats wot i heard...dont blame me afterwards,do learn everything, but ...yeah

Is plan diagram coming
I dont get question1 we have to perform proteintest on enzyme then we have to use the same enzyme.on starch to hyrdolyse it??
How do we do that add water and drops.on enzyme? Then do reducing sugar test
Also whst if they ask to add the.enzyme in sucrose!!? Then will the benedict result be oostive or negtive

dude u DONT ve to use the enzmy to hyrdolise the starch....!!!! there is another method for tht... come on guys...have not u studied tht??

Can somone please draw plan diagram of monocot stem must we show fibres?

 

[stareaj]

Yes ive done the other method but thats to hydrolyse sucrose is it the same forstarch the add hcl heat.......

[stareaj]

Do u have tge same for buirets test?
Thanks

 

[beeloooo]

for non reducing

 

[beeloooo]

Do u have tge same for buirets test?
Thanks

hey, these are some tips for plan drawing for slide qs

A plan diagram shows the distribution of tissues in a section. It also shows the proportions of the
different tissues. Although called a low power plan diagram you may use high power to identify
the different tissues and to be sure you are putting the boundaries of those tissues in the right
place. You do not draw any cells in a lower power plan diagram.
When you make a plan diagram, follow these simple rules:
o make the drawing fill most of the space provided; leave space around the drawing for
labels and annotations (if required by the question)
o use a sharp HB pencil (never use a pen)
o use thin, single, unbroken lines (often called ‘clear and continuous lines’)
o show the outlines of the tissues
o make the proportions of tissues in the diagram the same as in the section
o do not include drawings of cells
o do not use any shading or colouring
Add labels and annotations (notes) to your drawing only if you are asked for these in the
question. Use a pencil and a ruler to draw straight lines from the drawing to your labels and
notes. Write labels and notes in pencil in case you make a mistake and need to change them.
You may leave your labels and notes in pencil – do not write over them in ink.

Thank you

sary log q THAG rai ho....these are all simple tests.......jst follow the instructions and observe colour changes......

Guyx What you 're trying to say? :O It wouldn't be the Enzyme practical? In which we have to hydrolyse starch by Amylase? :O

 

[beeloooo]

^MALIK most probably no . from where did u here it will be ?

 

[Alool]

GUYS , HE MEANT THAT
for sucrose do the non reducing test
for glucose do the reducing test
for starch do the iodine test
and for fungal amylase do the biuret test for proteins

don't confuse urselves... and if theres anything extra it will be clear when u read the question and instructions

 

[Malik777]

But I heard it would be the enzyme practical? :S

hey friends need a gud website for microscopic images
