That would be the smallest possible peptide but then you could keep adding amino acids and form polypeptides. A fourth bond attaches a carbon to a side group that varies among different amino acids.

All attached to same carbon atom the acarbon or alpha carbon.
Amino acids linked by peptide bonds. The amino acids are linked by what are peptide bonds the order of amino acids is determined by the order of nucleotides the genetic alphabet in a gene of dna which in turn determine how the protein folds up and functions. The covalent chemical bonds are formed when the carboxyl group of one amino acid reacts with the amino group of another. When many amino acids are joined the product is called a polypeptide.
Proteins may have thousands of amino acid units. A polypeptide is a long continuous and unbranched peptide chain. A peptide bond is an amide type of covalent chemical bond linking two consecutive alpha amino acids from c1 carbon number one of one alpha amino acid and n2 nitrogen number two of another along a peptide or protein chain.
It can also be called an eupeptide bond to separate it from an isopeptide bond a different type of amide bond between two amino acids. The process of linking amino acids into proteins begins in the cell nucleus. Three amino acids can be joined by two peptide bonds to form a tripeptide.
What type of hormone that has 39 amino acid peptide synthesized by the pituitary gland. When a few amino acids are joined in this fashion the structure is called an oligopeptide. The shortest peptides are dipeptides consisting of 2 amino acids joined by a single peptide bond followed by tripeptides tetrapeptides etc.
These side groups are important as they affect the way a proteins amino acids interact with one another and how a protein interacts with other molecules. This bond is between the carboxylic acid group of one amino acid and the amino group of another react in a dehydration. A dipeptide would have two amino acids.
And a very high level overview of this reaction is that this nitrogen uses its lone pair to form a bond with this carbonyl carbon right over here. Amino acids are linked together by peptide bonds to form peptide chains. Similarly amino acids can be linked to form tetrapeptides and pentapeptides.
Adrenocorticotropic hormone acth a tropic hormone produced and secreted by the anterior pituitary that stimulates the production and secretion of steroid hormones by the adrenal cortex.
