Amino acids are joined together through dehydration synthesis to form a peptide bond. Many other proteins consist of two or more polypeptide chains that must assemble properly to form a functional complex. Amino acids have a central asymmetric carbon to which an amino group, a carboxyl group, a hydrogen atom, and a side chain (R group) are attached. Also provided are nucleic acids coding for the same, host cells expressing the same, and methods of use therefor. Proteins Carbs,lipid Polymer; a long chain of monomer. Tags: Question 18 . Protein polypeptide chain 8. A polypeptide is, very generally, seen as a molecule composed of 50 or more amino acids. These involve atoms in the polypeptide backbone, as well as atoms in the amino acid side chains. Unlike carbohydrates, proteins never show branches; they are just a chain of carboxyl groups joined to amino groups. Polypeptide chains have some flexibility but are restricted in . The synthesis of a polypeptide, however, is not equivalent to the production of a functional protein. Specifically it is a simple triol (alcohols with three hydroxyl groups). Tertiary. of a protein made up of more than one polypeptide chain Hydrogen and covalent bonds between side chains (R groups) of various amino acids contribute, as do hydrophobic interactions and van der Waals interactions. Polypeptide chains can form tightly coiled helical structures that are stabilized by hydrogen bonding between the NH proton of one amino acid and the C=O group of the amide bond of the fourth amino acid residue in the main chain.
