Chemicals and services for the Biochemistry / Peptides
Basic Structure
Amino Acids: The building blocks of peptides, each consisting of an amino group (-NH₂), a carboxyl group (-COOH), and a unique side chain.
Peptide Bond: A covalent bond formed between the amino group of one amino acid and the carboxyl group of another, releasing a molecule of water (dehydration synthesis).
Classification
Dipeptides: Consist of two amino acids.
Tripeptides: Three amino acids.
Oligopeptides: Typically between 4 and 20 amino acids.
Polypeptides: Longer chains, often considered proteins when they fold into functional structures.
Functions
Hormones: Some peptides act as hormones, such as insulin, which regulates glucose levels.
Neurotransmitters: Peptides like endorphins and substance P play roles in the nervous system.
Enzymes: Many enzymes are peptides or proteins with catalytic functions.
Antimicrobial Peptides: These are involved in immune responses, such as defensins.
Synthesis and Degradation
Synthesis: Peptides are synthesized in cells through processes involving ribosomes (translation) or chemical synthesis methods.
Degradation: They are broken down by proteases, which are enzymes that hydrolyze peptide bonds.
Applications
Medicine: Peptides are used in therapeutics for their specificity and low side effects, such as in hormone replacement therapy or targeted cancer treatments.
Biotechnology: Peptides can be used as probes, in vaccines, or as tools for studying protein interactions.
