Any compound consisting of two or more amino acids, the building blocks of proteins. Peptides are combined to make proteins.
Two or more amino acids covalently joined by peptide bonds. An oligomer component of a polypeptide. A dipeptide, for example, consists of two (di) amino acids joined together by a peptide bond or linkage. By analogy, this structure would correspond to two joined links of a chain.
A class of chemicals that form the basis of proteins.
Compound formed of two or more amino acids.
Compounds formed when amino acids are linked together through the —CO—NH— (peptide) linkage. Two amino acids so linked form a dipeptide, three a tripeptide, etc.
Compounds of two or more amino acids linked by a peptide bond.
Two amino acids linked together by a peptide bond.
Single chains of amino acids joined together by peptide bonds.
A peptide is more than one amino acid linked together by a peptide bond. A dipeptide contains two amino acids, while a tripeptide contains three. Polypeptides are often defined as having more than three peptides. Some references consider a polypeptide to have up to 100 amino acids, while others limit the definition to only 50. Molecules with greater than these numbers of amino acids linked by peptide bonds are considered proteins. The potential metabolic influences of certain short peptides found in foods or produced from proteins during the digestive process is beginning to receive much attention in research and may some day prove to have implications for health or performance of athletes.
Compound formed of two or more amino acids linked by peptide bonds. Proteins are made up of chains of polypeptides.
A molecule consisting of two or more amino acids linked by bonds between the amino group (-NH) and the carboxyl group (-CO). This bond is known as a peptide bond.
A peptide is a portion of a protein composed of two or more amino acids. When peptides contain a large number of interconnected amino acids, they’re referred to as polypeptides, and groups of polypeptides form proteins. Within the body, peptides take on roles as hormones and endorphins, among other forms.
