Abstract
New peptides are disclosed which have biological activity of the same type as known calcitonins and which do not have a leucine in position 19, a glutamine in position 20, a threonine in position 21, and a tyrosine in position 22. All four amino acids are omitted. Also resin peptides are disclosed which may be converted to peptides having such biological activity; and processes for producing said resin peptides and said calcitonin peptides.
