A C-terminal PEG-like brush polymer conjugate refers to a specific configuration of a polymer attached to the C-terminal end of a protein or peptide. Polyethylene glycol (PEG), a commonly used polymer, enhances the therapeutic performance of proteins/peptides by improving their solubility, stability, and half-life in the body, thereby reducing their immunogenicity. A "brush polymer" structure further optimizes these properties by creating a dense, brush-like arrangement of polymer chains, which can offer superior shielding and reduced aggregation compared to linear PEGylation. Attaching this brush polymer specifically at the C-terminal end helps maintain the protein's active site availability, crucial for therapeutic efficacy. Such conjugates are increasingly investigated for potential in drug delivery and bioconjugate therapeutics, aiming to create more effective and longer-lasting treatments.

Generally, thermoset plastics are not used in injection molding processes due to their unique characteristics. Unlike thermoplastics that melt when heated, thermoset plastics undergo a chemical change when subjected to heat, becoming rigid and permanently setting their shape. This irreversible process prevents thermoset plastics from being re-melted and reshaped, which is a fundamental aspect of injection molding. However, there are specialized injection molding techniques designed for thermosetting polymers, such as reaction injection molding (RIM), where the material is injected into the mold in a liquid state and then chemically hardens. These methods are less common and require specific equipment and molds to handle the chemical curing process.

When comparing an amino acid with water in terms of "lighter and warmer," we're looking at physical state, specific heat capacity, and thermal conductivity. Amino acids are organic compounds that are solid at room temperature, whereas water is a liquid. The term "lighter" can refer to density or mass - in a comparable volume, an amino acid might be denser than water, but this varies among the different amino acids. For "warmer," if we consider specific heat capacity (the amount of heat one gram of a substance must absorb to increase its temperature by 1°C), water has one of the highest specific heat capacities (about 4.18 J/g°C) among common substances, meaning it can absorb a lot of heat before it gets warmer. Most solids, including amino acids, typically have lower specific heat capacities, which means they would generally warm up faster than water when exposed to the same amount of heat. Thus, an amino acid might not necessarily be lighter in terms of density, but it could warm up more quickly than water due to its lower specific heat capacity.
