What are proteins? Explain their different forms |
| Answer» Proteins are complex\xa0biomolecules\xa0that are made up of smaller units known as\xa0amino acids.\xa0Due to different rearrangement of amino acids, the\xa0structure of proteins divides into four types:\tPrimary- the covalent linkages of the proteins\tSecondary- the linear peptide chains fold either into an alpha-helical structure(coiled) or a beta-pleated structure(sheets) which contain\xa0hydrogen bonds.\tTertiary-\xa0The arrangement and interconnection of proteins into specific loops and bends forms the tertiary structures. This structure contains hydrogen,\xa0ionic\xa0and disulfide bonds.\tQuarternary- this structure is proteins containing more than one peptide chain. | |
