![]() (Milio, Frank R, no year) Proteins that provide all the essential amino acids in about the right proportions for human nutrition are called complete proteins. Amino acids incorporated into proteins are covalently linked by peptide bonds. Picture 4.1 The structure of Amino Acid (Milio, Frank R, 1995) For classified, chains with fewer than 50 amino acids are often called peptides, while the term protein is generally used for longer chains. Note that all amino acids contain carboxylic acid groups (-COOH), amino groups (-NH2), and substituent, or replaceable, side chains (-R) (Milio, Frank R, 1995) ![]() Reaction 4.1 Hydrolysis of protein (Fessenden, 1982) The general structure from amino acid is shown in Figure below. When protein hydrolized formed amino acid. Regardless of their function, all proteins have fundamentally similar srtucture and are made up of many amino acids linked together in a long chain. To understand causes precipitation in protein with colour reactionīasic Theory Definition of protein Protein are essential compound of animal organism. To differentiate denaturation reaction of protein its caused by acid, salt and salt from heavy metals, and heating based on observation. To differentiate the characteristic solubility of protein’s reversibly and irreversibly : Learn the characteristic and colour reaction from Protein
