He also writes, I know nothing to indicate that. Nixon was aware in advance of the plan to break into the Democratic headquarters.. Documents and tapes available at the National Archives also contradict Mr. Magruder's reported statements.
All Enzymes are basically proteins. Amino acids are building blocks of proteins.   Another Answer   No enzyme 'turns' a protein into multiple amino acids. What an enzyme â¦ may do is split a protein down to its substituent amino acids. (Proteins are inherently long stings of amino acids joined by peptide bonds.) The group of enzymes that split proteins (hydrolyse proteins) to their single amino acids are called proteases.   Pepsin is a protease released by the stomach.
Although the amino acid sequence (also known as the protein's primary structure) does not change, the protein's shape may change so much that it becomes dysfunctional, in which case the protein is considered denatured. Pepsin, the enzyme that breaks down protein in the stomach, only operates at a very low pH. At higher pHs pepsin's conformation, the way its polypeptide chain is folded up in three dimensions, begins to change. The stomach maintains a very low pH to ensure that pepsin continues to digest protein and does not denature.
