New strategy to treat brain bleeding

Subarachnoid hemorrhage (SAH)—bleeding from a ruptured aneurysm—leads to delayed cerebral vasospasm (blood vessel constriction) and stroke. SAH morbidity and mortality are high, and therapeutic options are limited.

Three peptides could be causing severe COVID-19 complications

A study published in July 2020 hypothesized a link between the presence of bradykinin, a well-known peptide, and severe cases of COVID-19. Vardan Karamyan, Ph.D., an associate professor and vice chair for the Texas Tech University ...

Peptide

Peptides (from the Greek πεπτίδια, "small digestibles") are short polymers formed from the linking, in a defined order, of α-amino acids. The link between one amino acid residue and the next is known as an amide bond or a peptide bond.

Proteins are polypeptide molecules (or consist of multiple polypeptide subunits). The distinction is that peptides are short and polypeptides/proteins are long. There are several different conventions to determine these, all of which have caveats and nuances.
