Question

name the type of bond formed between two polypeptide s​

Answer 1

Answer:

Amino acids are joined together by a special type of covalent bond (peptide bond) to form linear structures called polypeptides. The polypeptides are then folded into specific structures to form the functional conformation of the protein.

Answer 2

Polypetide chains can be linked together by :

Explanation:

• Hydrogen bonds,
• Ionic bonds,
• Covalent bonds.

• By linking amino acids to each other using peptide bonds, polypeptide chains are formed.
• Peptide bonds are formed between the carboxylic group and amino group of two successive amino acids respectively.
• Two polypeptide chains can be linked together by:

1. Hydrogen bonds between the functional groups of the polar amino acids (like tyrosine and serine).
2. Ionic bonds between positively and negatively charged amino acids (like arginine and aspartic acid).
3. Covalent disulphide bond between two cysteines to form a cystine dimer.
