Lipid polyesters constitute the structural components of two cell wall modifications, the plant cuticle and suberin-containing diffusion barriers. In this video, we describe a method to depolymerize cutin from whole delipidated leaves. The method can be applied to investigating mutants compromised in either cutin or suberin biosynthesis.

Detecting Reactive Oxygen Species

Reactive oxygen species are chemically active, oxygen-derived molecules capable of oxidizing other molecules. Because of their reactive nature, there are many deleterious effects associated with unchecked ROS production, including structural damage to DNA and other biological molecules. However, ROS can also be mediators of physiological signaling. There is accumulating evidence that ROS play significant roles in everything from activation of transcription factors to the mediation of...

Reactivity of Enols

2023
Enols are a class of compounds where a hydroxyl group is attached to a carbon–carbon double bond, which implies that it is a vinyl alcohol. A carbonyl compound with an α hydrogen undergoes keto–enol tautomerism and remains in equilibrium with its tautomer, the enol form. Usually, the keto tautomer is present in a higher concentration than the enol tautomer due to the higher bond energy of C=O compared to C=C. Moreover, the direction of the keto–enol equilibrium is governed by factors like...

Cross-reactivity

Overview The ability of a single antibody to recognize multiple structurally similar epitopes is an important immune defense strategy that enables the host to efficiently defend against many potentially threatening pathogens. However, cross-reactivity also elicits allergy symptoms against related allergens. It is increasingly important to understand the principles of cross-reactivity, as antibodies are actively being developed as therapeutic modalities for diverse diseases, including cancer.
FAQs
Molecular structure influences how readily a monomer enters a growing polymer chain or reacts through step-growth pathways. Functional groups determine the available reaction sites, while electronic properties affect the behavior of those sites and any reactive intermediates. Comparing these features helps chemists anticipate reaction rates and select monomers that produce desired polymer structures and properties.
Steric effects describe how the size and arrangement of groups around a reactive site can influence its accessibility. Crowded structures may change how readily the monomer participates in polymer-forming reactions, which can affect reaction rate and molecular-weight development. This factor must therefore be considered alongside functional groups and electronic properties rather than evaluated independently.
Temperature, solvent, and catalyst conditions can modify the environment in which monomers react and can alter the behavior of reactive species. Their effects may change polymerization rate, the development of molecular weight, and the relative participation of different monomers. Controlling these variables is important when chemists seek reproducible polymer formation and targeted material properties.
The stability of a reactive intermediate helps determine how a polymer-forming reaction proceeds. Depending on the system, the intermediate may be a radical, ion, or active coordination complex, and its stability can influence reaction rate and which monomer reacts preferentially. These differences help explain changes in copolymer composition and sequence distribution.
Chemists compare monomers by considering their molecular structures, functional groups, steric effects, electronic properties, and behavior under specified reaction conditions. The relevant interpretation depends on whether polymer formation follows chain-growth or step-growth chemistry. Such comparisons support predictions about relative reaction rates, copolymer composition, sequence distribution, and molecular-weight development.
Monomer reactivity can help predict how different monomers contribute to a copolymer and how their sequence distribution may develop. Those predictions are useful for connecting chemical composition with the resulting polymer's mechanical, thermal, and chemical properties. This information supports the design of materials for plastics, elastomers, coatings, adhesives, and specialty polymer applications.
Reactivity affects how quickly polymerization proceeds and how molecular weight develops, both of which influence the material obtained and its processing behavior. By accounting for structure and reaction conditions, chemists can design polymers with targeted mechanical, thermal, and chemical properties. These relationships are relevant when developing plastics, elastomers, coatings, adhesives, and specialty polymers.
Monomer reactivity connects molecular-scale factors with polymer-scale outcomes. Studying it can reveal how functional groups, electronic properties, steric effects, temperature, solvent, and catalysts influence composition, sequence distribution, and molecular-weight development. In chemistry research, these relationships provide a basis for designing polymer systems whose performance matches the requirements of a specific application.
