Detailed explanation-1: -The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries. The largest group of amino acids have nonpolar side chains.
Detailed explanation-2: -Primary Structure (1˚) The primary structure of a peptide or protein is the linear sequence of its amino acids (AAs). By convention, the primary structure of a protein is read and written from the amino-terminal (N) to the carboxyl-terminal (C) end. Each amino acid is connected to the next by a peptide bond.
Detailed explanation-3: -The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
Detailed explanation-4: -Methionine is the first amino acid of the chain.
