### organic amide:

Peptide
* Are fragments of a whole protein molecule.
* Many peptides occur in nature only in minute quantities.
* Most peptides are soluble in distilled water.
* Some peptides are very hygroscopic.
* Toxins from Amanita.
* also regulate various aspects of the nervous system.
* antagonists with the ability to modulate the activity of multiple chemokine receptors.
* are a diverse group of compounds that mediate communication among neurons and glia
  - absorbed into the mucosal cells by pinocytosis
  - active substances used by the pharmaceutical industry
  - also useful in the development of new diagnostic tools
  - amides
  - amino acids strung together very much like pearls strung along a necklace
* are among the more significant messengers in the body
  - most common chemical structures found in animals
  - chains of amino acids
  - expensive to produce, and they degrade quickly
  - important in countless areas of biomedical research
  - links of amino acids that boost collagen and elastin production
  - messenger molecules that have specific sites on cell surfaces to which they bind
  - polymers
  - powerful isolates of amino acids derived from much longer whole whey protein molecules
  - regulators of the activity of other molecules, like proteins
* are short chains of amino acids that can take on many structural forms
  - polymers of amino acids
* are small chains of amino acids still linked together
  - acids, the building blocks of protein
  - consisting of few amino acids
  - proteins that play a key role in body chemistry
  - smaller, low molecular weight compounds, sometimes as small as two amino acids
  - sources of amino acids and nitrogen for cells
* are the building blocks of proteins
  - long chains of amino acid residues that make up a protein subunit
  - therefore an important factor of neuronal plasticity
  - ubiquitous modulators of neural networks
  - usually too small to have extensive secondary or tertiary structures
  - what make up proteins
* based on the hydrophobic proteins are also effective inhibitors of adhesion.
* begin to fold into secondary structure even as they are being translated.
* bind to eosinophils in the rat stomach.
* binding cleft is open end.
* blockers to prevent culture agglutination.
* can serve as antigens capable of being recognized by the immune system.
* changes in the parabrachial nucleus following cervical vagal stimulation.
* consisting solely of glutamine residues can form insoluble complexes.
* contribute to the sensory quality of circumgenital scent marks in marmoset monkeys.
* enhance the fullness of beer.
* form the constituent parts of proteins.
* hormonesa e soluble in water.
* intermediates in the degradation of cellular proteins.
* is an amide
  - array class
  - produced in the laboratory, and is of known potency
* libraries to discover structural basis of protein protein interactions.
* ligands for a sugar-binding protein isolated from a random peptide library.
* mostly adjust or regulate metabolic events.
* oligomers for holographic data storage.
* reagents for research in physiology and other fields.
* regulate some aspects of protein expression.
* substrates for tyrosine kinases.
* transform themselves like tiny smart Legos into millions of essential substances.
