Peptide
Peptides are short polymers of amino acid monomers linked by peptide bonds. They are distinguished from proteins on the basis of size, typically containing less than 50 monomer units. The shortest peptides are dipeptides, consisting of two amino acids joined by a single peptide bond...

TLR 1
TLR 1 is a member of the Toll-like receptor family of pattern recognition receptors of the innate immune system. TLR1 recognizes pathogen-associated molecular pattern with a specificity for gram-positive bacteria...
