In biology, what does denatured mean? Rating Newest Oldest. Best Answer: Denaturation is a process in which proteins or nucleic acids lose their structure by application of some external stress or compound. If proteins in a living cell are denatured, this results in disruption of cell activity and possibly cell death. Source(s): http://en.wikipedia.org/wiki/Denaturatio...

What does denature mean? What happens to enzymes when they are denatured? Relevance. Rating Newest Oldest. Best Answer: denature means change shape. when enzymes are denatured, due to a severe increase in temperature, or a sudden change in pH, their active site (which is where the substrate enters to be broken down) changes shape, meaning that the enzyme will no longer work.hese changes include loss of activity (in the case of enzymes) and loss or (alteration) of antigenicity (in the case of antigens). When the enzymes (which are proteins) are denatured, they loose their structure and function. Source(s): Oxford Medical Dictionary. elena · 5 years ago.

Which of the following would be affected when a protein is denatured? How does denaturation affect the ability of a protein to function? Denaturation of a protein means loss of the protein's function due to structural change in the protein caused by some chemical or physical factor such as high temperature or u…nfavorable ph. The bonds that hold the structure together get affected which leads to the loss of structure and function.

What Does It Mean if an Enzyme Is Denatured? When an enzyme becomes denatured, it has lost some of its original properties. Denaturing can occur because of heat or from chemical reactions that have rendered the enzyme inactive. An enzyme is a biological protein molecule made up of thousands of amino acids. Enzymes have specific functions in the body, such as working to break down food or causing other chemical processes.

Denaturation (biochemistry) Denaturation is a process in which proteins or nucleic acids lose the quaternary structure, tertiary structure and secondary structure which is present in their native state, by application of some external stress or compound such as a strong acid or base, a concentrated inorganic salt, an organic solvent, radiation or heat. If proteins in a living cell are denatured, this results in disruption of cell activity and possibly cell death. Protein denaturation is also a consequence of cell death. De

Denaturation (biochemistry) If proteins in a living cell are denatured, this results in disruption of cell activity and possibly cell death. Denatured proteins can exhibit a wide range of characteristics, from conformational change and loss of solubility to aggregation due to the exposure of hydrophobic groups. Protein folding is key to whether a globular protein or a membrane protein can do its job correctly.

When enzymes are denatured, what type of bonds are broken? Trending Now. Answers. Best Answer: Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape.

Nitrogen cycle Denitrification is the reduction of nitrates back into nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such as Pseudomonas and Clostridium in anaerobic conditions. They use the nitrate as an electron acceptor in the place of oxygen during respiration.

Denaturation and Coagulation It is a permanent change in the structure of proteins. The functional property of protein, denaturation is useful in food preparation for example whisking eggs which is a component of many food products, the marinating a piece of meat where the acid tenderises the meat before cooking, making sour cream and yoghurt.

Decay development The boundary-setting process that resists loss of normal wood function and resists the spread of discoloration and decay has been referred to as compartmentalization. Discoloration is the orderly response of the tree to microorganisms resulting in darkened wood but no strength loss.

Denaturation (biochemistry) DNA denaturation occurs when hydrogen bonds between Watson and Crick base pairs are disturbed. The non-covalent interactions between antiparallel strands in DNA can be broken in order to open the double helix when biologically important mechanisms such as DNA replication, transcription, DNA repair or protein binding are set to occur.
