The interface formed between two hydrophobic molecules in the context of the aqueous environment of the cell cytoplasm is formed mostly through:   A. Hydrogen bonds   B. Covalent bonds   C. Van der Waals interactions   D. Ionic bonds   E. None of the above

    Different bonds are present in a biological system. They are generally subdivided into 2 categories non-covalent and covalent bonds. Non-covalent bonds are weak bonds whereas covalent bonds are strong bonds. A total of 300 amino acids are present in the biological system out of that 20 are part of protein remaining are non-standard amino acids. depending upon the side-chain amino acid are categorized into polar, nonpolar, basic, and acidic. and these groups of amino acid plays important role in forming different Intra and intermolecular forces between R-groups of amino acid, the peptide bond, resulting in a particular shape of the polypeptide.
