What is thermoplastic?
Thermoplastic is a polymer that can remelted and remolded many times.Thermoplastic is a polymer resin based plastic that softens/melts when heated.Thermoset-plastic is a polymer resin based plastic that polymerizes and/or crosslinks when heated, hardening it. If heated more it just chars.
Why is protein destroyed by heating?
Proteins break down when heated because the chemical bonds dissociate if they are heated sufficiently. This is how heat kills living things, like bacteria which are killed by the heat when sterilizing medical instruments.
What happens to plant cells when they are cooked?
Plant cells are made of long chains of protein which are made of long chains of amino acids. Each amino acid has an 'r' group which defines it's own special properties. It's the 'r' group attractions to each other that make them clump up and form these long strands of cell wall (fiber) which defines the plant cells. As they are heated, the 'r' group attractions break apart. Therefore denaturing it and forming new molecules. Hope I answered your question! :D -IB Biology Teacher
Can enzyme change?
Yes.VocabularyEnzymes- long linear chains of amino acids that can foldDenaturization- a process where enzymes move to their second structureMost enzymes can be denatured by heated or by certain chemicals. Some enzymes' denaturization is reversible, others is irreversible.
How is crude made into products?
Crude oil contains mixture of various types of hydrocarbons. The hydrocarbons are separated by fractional distillation. Different hydrocarbons have different boiling points and therefore after crude oil is heated, shorter chains of hydrocarbons which have lower boiling point will become gas and can be easily separated one by one from hydrocarbons with shorter chains to longer chains. The brief products are Petroleum Gas, Gasoline, Kerosone, Heating Oil, Lubricating Oil and Bitumen in order of increasing molecular size.
What happens to the albumin of an egg?
The protein coagulates when heated.
What happens when a protein is heated to 60 degrees Celsius?
it denatures
What will happen in a sealed bottle when the air is heated and then allowed to cool?
The bottle will collapse when the bottle has heated air
Does biuret's reagent turn lavender when heated?
No, it changes lavenderish when protein is present.
Why do you believe the Cold War conflicts became more heated in Korea?
It got heated because there was actually fighting allowed!
What does coagulation mean in cooking?
COAGULATION Individual protein molecules in raw meat are wound-up in coils, which are formed and held together by bonds. When meat is heated, the bonds break and the protein molecule unwinds. Heat also shrinks the muscle fibres both in diameter and in length as water is squeezed out and the protein molecules recombine, or "coagulate". This is the final stage of the denaturation process, which results in the setting of protein. As coagulation occurs the amino acid chains undergo changes during the process of coagulation. The peptide bonds are broken causing the amino acid chains to unravel, causing the meat to become more tender. It makes the food more pleasant to eat and easier to digest as it coagulates.
What are the best sources of protein in protein shakes recipes?
The primary source of protein in protein shake recipes is Whey Powder, which comes in many different flavors. Whey itself is the liquid formed during the production of cheese. It is heated and dried and then processed for consumption as a dietary supplement.
Why does the egg go in to the flask when heated?
When an egg is heated, the protein present within it(the egg white), called albumin gets denatured. This is because protein structures break at high temperatures. As a result, the liquid albumin forms a thick white mass.
Why does an enzyme become denatured when heated?
Heat breaks chemical bonds in protein molecule which distorts its structure and catalytic activity .

Why is it important not to heat the food substance which is being tested for protein?
Proteins that are heated to a very high temperature will become denatured, and inactive
What happens to albumin strands in an egg when heated?
the albumin is a protein, and the shape of this protein chanegs when it is heated (scientists call this the protein denaturing). You can think of it like this: If you have a strand of uncooked spaghetti, and you heat it, it changes shape and goes from being staight and hard to not being able to stand itself upright and able to be bent. Proteins are normally all jumbled up, and when they get denatured, they tend to straighten out, like the oppisate of what happened with the spaghetti.
