Question: what is the difference between the structure of glycylserine and the structure of serylglycine?
Answer: 2. Glycylserine and Serylglycine are dipeptide molecules consisting of each of glycine and serine but in Glycylserine one H of NH2 group of serine is condensed with OH of COOH group of glycine, thus forming amide linkage. Similarly, in Serylglycine OH of COOH group of serine condenses with H of NH2 group of Glycine.
