Perhaps you have also wondered what the differences between proteins and peptides are.
Read the following article carefully to get the answer to your question.
Proteins and peptides are compounds that are responsible for regulating basic functions in living cells. The word protein is derived from the Greek word proteos meaning priority or first, and the word peptide is derived from pepsis meaning digestion or peptone meaning digestion products of proteins. However, if a protein is degraded or degraded by a specific enzyme, it is converted into different peptide fragments.
Peptides are sequences of amino acids that are connected to each other by peptide bonds (amide bonds) and are structurally very similar to proteins, but with the difference that proteins have a higher molecular weight. Molecules made of 50 or more amino acids are usually considered proteins, and those with fewer amino acids are considered peptides, but there is no clear boundary between these two groups of substances. Protein chemistry is clearly a large subfield of biochemistry. On the other hand, the chemistry of peptides is closer to the realm of organic chemistry due to its lower molecular weight.
