FDSC 1049 Lecture : Protein Chemistry Student Notes 2014
Document Summary
Physical properties: polymers (links) of amino acids joined by peptide bonds, referred to as polypeptides, 4 calories/gram, conjugated or unconjugated. Unconjugated = not bound to any other substances and contain only amino acids. Phosphoproteins: contain phosphate groups in their structure (milk casein) Denaturation the unfolding of a protein structure, usually due to acid or heat. Fdsc 1049: the normal spatial arrangements and the proteins functional properties are altered or lost when this occurs, examples, ______________ is made by adding acid and high temperature which causes coagulation to occur. Protein-protein interaction takes: scrambled eggs change by heat. place. Food proteins are typically one of two shapes: globular spherical like a ball, most are soluble in water, ex: _________________, fibrous elongated like a twisted rope, generally insoluble in water, ex: __________________ Emulsification : since protein molecules contain both ____________ and ___________ regions, they can situate themselves between the two phases to stabilize them, ex.
