Vasopressin: CYFQNCPRG Oxytocin: CYIQNCPLG Calculate the pI of each peptide. How could the differences affect their function.
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.

Calculate the pI of each peptide.
How could the differences affect their function.
Vasopressin is a antidiuretic hormone and regulates the water homeostasis, its major function are - increase the amount of solute-free water reabsorbed back into the circulation from the filtrate in the kidney tubules. it constricts the arterioles, increase the vascular resistance and raises the arterial blood pressure.
Oxytocin is a hormone and neuropeptide involved in reproduction, childbirth, etc. It stimulates the uterine contractions during labor and childbirth and also stimulates the contractions of breast tissue for lactation after the childbirth.
