Detailed explanation-1: -Three key ideas that explain the huge range of possible polypeptides. The properties R-groups of amino acids can possess. The order/sequence of the amino acids of which the protein is composed. Formed by covalent peptide bonds between adjacent amino acids.
Detailed explanation-2: -Amino acids are linked together by condensation to form polypeptides. There are 20 different amino acids in polypeptides synthesised on ribosomes. Amino acids can be linked together in any sequence giving a huge range of possible polypeptides.
Detailed explanation-3: -Because amino acids can be arranged in many different combinations, it’s possible for your body to make thousands of different kinds of proteins from just the same 21 amino acids.
Detailed explanation-4: -As a general rule, a peptide contains two or more amino acids. And just to make it a little more complicated, you will often hear scientists refer to polypeptides – a chain of 10 or more amino acids.
