Bromelain separates the amino acids in the enzymes that cause browning by breaking the peptide bonds.
Explanation:
Enzymes speed up chemical reactions by lowering activation energy.
An enzyme from the stem of pineapple is called Bromelain also known as cysteine protease. It is obtained by cutting pineapple and filtering the juice of it.
Bromelain extract is a mixture of protein-digesting enzymes and several other substances in smaller quantities.
The monomers in Bromelain are numerous sub units of Sulfhydryl proteases. A free sulfyhydryl group of a cysteine amino acid side chain is required for function. By seperating proteins from amino acids the reaction that breaks up enzymes occurs.
Answer:
The molecules absorb heat and acquire more kinetic energy.
Explanation:
In a solid, the solids only vibrate about their mean positions but do not translate. When energy is supplied to the molecule in the form of heat, the molecules vibrate faster. Eventually, they acquire sufficient energy to leave their mean positions and translate. Hence the solid crystal collapses.
When ice is heated, water molecules acquire sufficient kinetic energy to translate. The intermolecular bonds are gradually broken in the solid framework as heat is absorbed. The heat required for this is known as the latent heat of fusion.
The temperature remains constant until phase transition is over, then temperature rise resumes.
TMS has 12 protons which are all equivalent and four carbons, which are also all equivalent. This means that it gives a single, strong signal in the spectrum, which turns out to be outside the range of most other signals, especially from organic compounds.
