WebThe unchanged -COOH group is written at the right-hand end. The end of the peptide chain with the -NH 2 group is known as the N-terminal, and the end with the -COOH group is the C-terminal. A protein chain (with the N-terminal on the left) will therefore look like this: The "R" groups come from the 20 amino acids which occur in proteins. A protein's lifespan is measured in terms of its half-life and covers a wide range. They can exist for minutes or years with an average lifespan of 1–2 days in mammalian cells. Abnormal or misfolded proteins are degraded more rapidly either due to being targeted for destruction or due to being unstable. See more Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues.
