Name common linkages in biological molecules

, Structural features of carbohydrates
Linear but most of the times forms rings. Sugars typically form
ring structures in aqueous solutions.
Structural features of amino acids
protein folding, binding to ligands, interaction with environment
Structural features of nucleotide
Nitrogenous Bases
Structural features of lipids
Membranes, evergy-rich fuel stores, pigments, and intracellular
signals
Monomers and linkages of polysaccharides
Simple sugars, linked together by glycosidic bonds
Monomers and linkages of polypeptides
Amino acids, forms peptide bonds
Monomers and linkages of nucleic acids
nucleotides, linked by phosphodiester links
Enthalpy application in biological systems
measure the heat absorbed or released during chemical
reactions
Entropy application in biological systems
