A peptide bond is a covalent linkage between the carboxyl group of one amino acid and the amino group of another. Formed during protein synthesis […]
Proteoglycans are macromolecules composed of a core protein linked to long chains of glycosaminoglycans (GAGs). Abundant in extracellular matrices, they provide structural support, regulate cell […]
Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen, typically in a 1:2:1 ratio. They serve as a primary source of energy for living […]
Cyclic AMP (cAMP) is a signaling molecule involved in intracellular communication. It is derived from adenosine triphosphate (ATP) and functions as a second messenger, activating […]
Guanosine Triphosphate (GTP) is a nucleotide involved in cellular energy transfer and signal transduction. Similar to ATP, it serves as a high-energy molecule, contributing to […]
Adenosine Triphosphate (ATP) is a nucleotide that serves as the primary energy currency in cells. It stores and releases energy through the transfer of its […]
Zinc finger DNA-binding domains are protein motifs that recognize and bind specific DNA sequences. Comprising zinc ions and amino acids, these structures enable targeted gene […]
A leucine zipper is a structural motif in proteins involved in DNA binding and protein-protein interactions. It consists of repeated leucine residues at regular intervals, […]
