General Structure of an Amino Acid General Structure of a Lipid Structure of Lactose Structure of Calcium Phosphate 1. Separating the Components of Milk The four components of milk are proteins, fats, lactose, and phosphates. Proteins The main components of a protein are amino acids, which are made up of a carboxylic acid, an amine, and an R group. Amino acids are joined together by peptide bonds. In an aqueous solution, proteins fold and form into a tertiary structure. Acetic acid speeds up this process, making the protein’s solubility decrease. A precipitate forms, and the protein denatures. Fats Fats are made up of glycerol and fatty acid hydrocarbon chains. They are hydrophobic

Acetate, an organic solvent, extracts the fat from the protein. Lactose Lactose is a carbohydrate and a disaccharide composed of glucose and galactose. Lactose is very soluble because of hydroxyl groups. As protein and fat are participated out, lactose remains soluble. Phosphates Phosphate can be isolated from lactose by adding calcium ions, which forms the precipitate calcium phosphate because calcium is insoluble. This is a single displacement reaction....
