When a protein has lost its 3D structure it becomes polypeptide chain with some secondary structure elements are they may simply degraded to it primary structure which is polypeptide chain.
3D structure is a native structure of protein molecule where it can have the correct folding stabilized by its intra and inter molecular interactions among its residues.
Proteins can loose its structure when they are exposed to a denaturing condition which is change in buffer environment such as pH, temperature,ion salts, metals and detergents such as SDS can unravel the proteins structure. Reducing agents such as DTT or 2-mercaptoethanol or often used with heat (95 degrees) to denature the protein completely while resolving them on the gel.
What else can I help you with?
What is the effect of temperature on protein shape and give an example?
In most cases, extremes of temperature denature (alter the 3D structure of) proteins. In biological systems that denaturing temperature may be fairly mild. Another term for protein denaturing is coagulation which is what happens to the proteins of a boiled egg.
Does whey protein kill people?
No, whey protein does not kill people. Whey protein is a high-quality protein supplement that many people use to help meet their daily protein needs. However, like any supplement, it is important to use whey protein in moderation and as part of a balanced diet.
What can happen if there is one wrong amino acid in a protein?
I feel like there are conflicting answers to this, probably because both play a role...tertiary structure is the actual 3-D structure, which dictates how the protein interacts on a molecular level, but primary structure ultimately determines tertiary...a recent practice question said primary structure, but I've seen tertiary as the answer before...Does anyone have a clear answer/reasoning for that answer?? interesting question. what happens if you change an important catalytic residue but maintain tertiary structure? no function. what if you denature something and it loses shape? no function. both are right. a question like this on the MCAT would definitely be more explicit, examples: it is found that a patient has a single amino acid mutation resulting in the change in activity of phosphofructokinase. this mutation most directly affects? -answer: primary structure, its a single amino acid mutation, the rest of the protein is probably the same. urea, a denaturing agent and byproduct of amino acid metabolism is found abnormally in other parts of the body. enzymes in this part of the body are unable to function properly most likely due to a change in: -tertiary structure. overall shape has changed.
What is a carrier protein?
A carrier protein is a type of protein that helps transport specific molecules across cell membranes. These proteins bind to molecules on one side of the membrane and release them on the other side, facilitating their movement into or out of cells. Carrier proteins play a crucial role in maintaining cellular function by regulating the transport of essential molecules.
Why is it important that each receptor protein binds to only one signal molecule?
Specificity in binding helps ensure that signals are properly transmitted and received in cellular communication. If a receptor protein binds to multiple signal molecules, it can lead to inappropriate responses or interference with normal cell signaling pathways. This selectivity allows for more precise control and regulation of cellular processes.
What is it called when an enzymes active site loses its shape?
When this happens to a protein, it is said to denature.Denature is caused commonly by very high or low temperature,concentrated acids or bases.Denature by high temperature is irrevesible.
What is the natural form of a skinwalker?
A skinwalker is believed to be a shape-shifting witch or sorcerer in Navajo culture. In its natural form, a skinwalker is said to resemble a human, but with the ability to transform into different animals.
What happens when it loses electrons?
all elements want to have a full valence shell and when an atom loses electrons it is said to become a cation.
When an object is being squashed it is said to be in?
It is said to be in a soft shape or in compression.
How does too much protein affect a puppy?
Protein is needed for all dogs bit minimal amounts of protein is healthier for puppies. Protein is said to assist in growth... too much isn't good for joints etc. Encorouging a puppy to grow any faster than its natural growth rate is just silly and dangerous.
When a metal like silver loses its shiny appearance it is said to?
tarnish.
Does whey protein boost your metabolism?
No they dont, protein helps you increase muscle size, muscles arent linked to fat
Why are balancing things like temperature and acidity so important to living things?
Enzymes are protiens. If you get the balance of pH or temperature outof wack, you can change the shape of the enzyme. Changing the shape of the said enzyme damages the protein, so it cannot do its job. This is called denaturing.
Why are people saying goodbye john cena you will be missed?
because wade barret said if he loses he is fired but if he win he will not be a part of NEXUS anymore but wade barett loses
Is a square a plane shape or a solid shape?
it is a plane shape because you said its a square
What did Scrooges nephew say that Scrooge loses by not spending any time with him?
Scrooge loses money and

Substances which take the shape of a container are said to have an "Indefinite Shape" or fluids
