Protein structure

Hello friends, Proteins are polymers of amino acids covalently linked through peptide bonds into a chain. Within and outside of cells, proteins serve a myriad of functions, including structural roles (cytoskeleton), as catalysts (enzymes), ...

Re: how to memorize the amino acid

Proteins linear polymers built of amino acids. The sequence of the amino acids decide the three dimensional fold of the protein. The sequence of amino acid also defines the flexibility or rigidity of an protein. This structural property ...
