Big science, small words.
Here's how peptides work, why they're so tricky to get into the body, and what scientists are exploring next — written so anyone can follow along. See a hard word? Hover, tap, or focus it for a plain-English meaning.
Try it hereNice. That's a tooltip. Every dotted word on this page has one. — the dotted words explain themselves.
What is a peptide?
Your body is built from tiny building blocks. A peptidePeptide — a very small chain of building blocks called amino acids. Too small to see. is a short chain of amino acidsAmino acids — the little "beads" that link together to build peptides and proteins., the same pieces that make up proteinsProtein — a long chain of amino acids. A peptide is like a short protein..
Think of amino acids like beads on a string. A few beads together make a peptide. A whole lot of beads make a protein. A peptide is so small that you could never spot one, even with the microscope in your classroom.
What "Research Use Only" means
Dissolv makes Research Use OnlyResearch Use Only (RUO) — made for scientists to study in a lab. Not food, not medicine, and not for people or animals to eat. peptides. That's a grown-up way of saying they are made for scientists to study in a lab.
They are not food, not medicine, and not for people or animals to eat. A good way to picture it: a chemistry set is great for learning and experiments, but it isn't a snack. Same idea here.
Why can't you just swallow a peptide?
Here's the puzzle scientists have to solve. Your stomachStomach — the pouch inside you that breaks food down using acid. is a bit like a super-strong washing machine full of acid. Its job is to smash food into tiny pieces so your body can use them.
That's perfect for lunch — but terrible for a peptide. If a peptide lands in your stomach, the stomach acidStomach acid — a strong liquid in your stomach that breaks food apart. and tiny helpers called enzymesEnzymes — tiny tools in the body that cut things into smaller pieces, like scissors. chop it up before it can do anything. This whole break-down process is called digestionDigestion — how the body breaks food (and peptides) into tiny pieces.. So for most peptides, swallowing simply doesn't work well.
A secret door under your tongue.
So how do you get a peptide into the body without the stomach smashing it? You use a different door.
The soft skin under your tongue and inside your cheek is called the mucosaMucosa — the soft, moist skin inside your mouth. It's thin and full of tiny blood vessels.. It's thin and packed with tiny blood vessels. Scientists study whether a peptide placed there can slip straight into the bloodstreamBloodstream — the blood moving around your body, like a delivery highway. and skip the stomach completely.
There are two science words for this special spot: sublingualSublingual — "under the tongue." (sub = under, lingual = tongue) means under the tongue, and buccalBuccal — "inside the cheek." means inside the cheek.
What's a dissolving strip?
A dissolving stripDissolve — to melt away into liquid, like sugar in water. is a thin sheet — a bit like a breath-freshening strip — that melts away when it gets wet.
Making one that carries a peptide is surprisingly hard. The strip has to protect the peptide, melt at just the right speed, and taste okay. Getting that recipe right is called formulationFormulation — the recipe science of what goes into a product and how it's made.. The extra helper ingredients that hold the strip together are called excipientsExcipients — the helper ingredients in a strip that aren't the main peptide (like the flour and eggs in a cake, not the flavor)..
What scientists measure
To find out if a strip works, researchers watch a few important things very closely.
BioavailabilityBioavailability — how much of something actually makes it into the body and can be used.
How much of the peptide actually makes it into the body — not just how much you started with.
StabilityStability — whether something stays in good shape over time instead of falling apart.
Whether the peptide stays in good shape over time, instead of breaking down while it sits on a shelf.
DissolutionDissolution — how fast something melts or dissolves.
How fast the strip melts. Too fast or too slow can both cause problems.
AbsorptionAbsorption — how the body takes something in, like a sponge soaking up water.
How well the mouth's soft skin can take the peptide in, like a sponge soaking up water.
Fewer needles. More questions worth asking.
Today, many peptides are given with a needle. Needles work — but a lot of people really don't like them. If scientists can perfect a strip that carries a peptide across the mucosa, then one day peptides could be far easier to study and work with. No needle needed.
That's the future Dissolv is working toward: needle-free peptide deliveryPeptide delivery — the science of getting a peptide into the body in a useful way., built on real biotechnologyBiotechnology — using living things and their tiny parts to build helpful new tools and products..
