proteicas

Proteicas is a term used to denote substances that are composed primarily of proteins or that have a protein-rich composition. In English, the more common descriptor is proteinaceous, but proteicas appears in multilingual or technical contexts to emphasize the proteic basis of a material or product. The concept is used across food science, biomaterials, and industrial biotechnology to classify materials whose main functional components are proteins rather than carbohydrates or lipids.

Proteicas can be single proteins, such as albumin, collagen, or casein, or complex mixtures such as gluten or milk protein blends. Their functional properties—solubility, gelation, emulsification, foaming, and water-binding capacity—depend on amino acid composition, protein structure, concentration, and environmental conditions including pH, temperature, and ionic strength.

In foods, proteicas contribute texture, mouthfeel, and nutrition; in biomaterials, they form hydrogels, scaffolds, and adhesives; in industrial applications, proteic formulations can serve as coatings or binders. The study of proteicas intersects proteomics, food technology, and materials science, focusing on how protein networks develop and respond to processing or biological cues.

Analytical methods used to study proteicas include protein assays (Bradford, BCA), electrophoresis (SDS-PAGE), and proteomic techniques (mass spectrometry) to determine composition and structure. Characterization often seeks to relate protein content to functional performance in a given context, such as texture in a food product or biocompatibility in a medical scaffold.

Examples of proteicas encompass dairy proteins like casein and whey, egg white proteins such as ovalbumin and ovomucin, plant proteins like soy and gluten, and animal-derived collagens. Notable proteic materials include gelatin, fibrin, and keratin-based products.
