Does the following contain Reducing Sugar and/or Starch? (one experiment for reducing sugar, another experiment for starch)
onion juice
lemon juice
potato juice
sucrose
glucose solution 1
glucose solution 2
glucose solution 3
water
reducing sugar
starch
artificial sweetener

Biuret test
Does the following contain proteins? If so, what would the relative concentration be? (1ml sample size)
Egg Albumen
Honey
Amino Acid Solution
Water
Protein Solution
Milk
Muscle Powder

Any help will be very helpful :D
Thanks in advance!
