These bonds hold proteins together
Webb25 jan. 2024 · The amino acids are held together by peptide bonds to form polypeptide chains. A peptide bond is an amide bond (-CONH) formed by the –NH 2 and –COOH groups of neighbouring amino acids. The molecule that results is known as an amide. An amide group, or peptide group, is a four-atom functional group with the formula C (=O)NH. Webb20 jan. 2024 · Hydrogen bonding is applicable in these biomolecules because of functional groups present. Some such are the carboxylic acid, alcohol or even amine groups. These provide either an hydrogen, oxygen or nitrogen for possible hydrogen bonds. Hydrogen bond in proteins [edit edit source] Hydrogen bonding within the "green fluorescent …
