BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The primary structure of a protein-its amino acid sequence-drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein’s unique three-dimensional shape.

Detailed explanation-2: -Because amino acid sequence determines protein structure and structure dictates biochemical function, proteins that share a similar amino acid sequence usually perform similar biochemical functions, even when they are found in distantly related organisms.

Detailed explanation-3: -What is the primary structure of a protein? The linear sequence of amino acids within a protein is called the primary structure of the protein. A sequence of just twenty amino acids, each of which has a special side chain, is made up of proteins. The side chains of amino acids are chemically distinct.

Detailed explanation-4: -The primary structure of a biological polymer to a large extent determines the three-dimensional shape (tertiary structure). Protein sequence can be used to predict local features, such as segments of secondary structure, or trans-membrane regions.
