Why is gelatin liquefied in the presence of gelatinase?
Gelatinase is an enzyme that breaks down gelatin by cleaving its protein bonds, leading to liquefaction of the gelatin. The enzyme hydrolyzes the gelatin molecules into smaller components, causing the gelatin to lose its gel-like structure and become liquid.
How does the dessert gelatin solidify?
it solidfy by the temperature
After the gelatin sat in the refrigerator for hours it started to CONGEAL?
To solidify
Can be added in place of cold water to make gelatin mixture congeal more rapidly?
Ice can be added in place of cold water to help the gelatin mixture congeal more rapidly. The lower temperature of the ice helps to solidify the gelatin faster.
Use context clues to determine the best definition of the term shown in all capital letters. After the gelatin sat in the refrigerator for hours it started to CONGEAL.?
The term "CONGEAL" likely means to thicken or solidify, as gelatin does when it cools.
Why does pineapple not work in gelatin?
The proteins in the pineapple called bromelain will break down the strands of protein in gelatin that forms jello. Hence, the effect of a fresh piece of pineapple on gelatin is able to keep the gelatin liquidfied.
Why did you refrigerate the gelatin cultures before observing them for liquefaction?
Refrigerating the gelatin cultures helps to solidify the gelatin, making it easier to observe any changes in the consistency (liquefaction) of the gelatin. It also slows down any enzymatic activity that may occur at higher temperatures, allowing for a more controlled observation period.
What is the product of p-aminobenzoic acid and ethanol?
p-aminobenzoic acid and ethanol in the presence of sulfuric acid yields benzocaine.
What happens when ethanol is heated in presence of concentrated H2SO4?
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
Will reheating your set jello still solidify?
Gelatin is a reversible colloid, so yes, if you melt a set jello, it should set again when chilled. However, other ingredients, such as pineapple, may alter the gelatin so that it does not set.
Is ethanol saturated?
No, ethanol is not considered a saturated compound. It is classified as an unsaturated compound due to the presence of a double bond in its chemical structure.
How do you make ethanol?
simply hydrate an alkene, that is addind water to it with the presence of a catalyst
