Introduction

The kidneys refer to the organs that are involved with several important regulatory roles in vertebrate animals. Kidneys play a crucial role in the urinary system as well as in the homeostatic functions such as electrolyte regulation, maintaining a balance between the acids and bases, and in regulating blood pressure. Kidneys filter the blood removing wastes, which are then taken to the urinary bladder as urine. During urine production, wastes such as ammonia and urea are excreted while substances such as glucose, water and amino acids reabsorbed. The kidney is also responsible for the production of hormones such as erythropoietin and ...

The peptide hormones are proteinous in nature and may have 3 to 200 amino acids residues. This class of hormones includes all the hormones of the hypothalamus and pituitary, as well as insulin and glucagon of pancreas. Peptide hormones are named based on their endocrine activity rather than their chemical structure; for example, growth hormone is thus named because one of its effects is to stimulate growth. The structure of a particular peptide hormone can vary among different species, with some homology between close relatives. Some small peptides are identical; for example, GnRH is identical among mammals but different in ...
