Detailed explanation-1: -Thus, cell protein occupies 20-30% of cell volume in most cells in a range of organisms which are evolutionally widely separated.
Detailed explanation-2: -The human body uses just 21 amino acids to make all the proteins it needs to function and grow. 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-3: -Protein is evaluated at ≈55% of the cell dry weight, followed by RNA at ≈20%, Lipid at ≈10% and DNA at ≈3% (the rest being polysaccharides, metabolites, ions etc.).
Detailed explanation-4: -How Many Amino Acids Do Help Build Proteins? Roughly 500 amino acids have been identified in nature, but just 20 amino acids make up the proteins found in the human body.
