All amino acids contain a central carbon, a side chain (R group), an amino group and a __________ group. - Carboxyl Amino acids can undergo a proton transfer, thus giving both a (+) and (-) charge. This molecular state is called the ________. - Zwitterion Amino acid that are unable to be synthesised from biochemical pathways within a cell have to be consumed through dietary intake. These are called _______ amino acids. - Essential When two amino acids join together, they are joined by an aide bond. This is also referred to as a _______ bond. - Peptide Which level of protein structure involves the amino acid sequence, but not the folding of the protein? - Primary Unfolding a protein using heat is a process called ________. This process does not affect the primary sequence of the protein. - Denaturation If a neutral amino acid is placed in a very basic environment (pH 10), it will lose a proton (H+) from the __________ functional group. - Carboxyl - COOH Disulphides bonds are covalent bonds between two _______ amino acids. - Cysteine The process of breaking the bonds between amino acids within a polypeptide is called a ______ reaction. - Hydrolysis All amino acids contain both an acidic carboxyl group and a basic ______ group. - Amino
