Proteins

Vocabulary for Proteins & Amino Acids

TermDefinition
Proteins large molecules required in the diet to help form muscle fibers as well as carry out numerous other vital functions in the body
Structural Proteins proteins which help to form and maintain the objects which form the structure of the body, including muscle tendons and ligaments
Contractile Proteins work closely with structural proteins; these allow for movement to occur and include actin and myosin
Storage Proteins act as biological reserves of necessary items such as amino acids and metal ions
Defensive Proteins protect the body from various threats; include antioxidants
Transport Proteins help to move items within the body; include hemoglobin
Signal Proteins proteins responsible for communication between cells; many hormones are in this category
Enzymes chemical catalysts which promote and regulate almost all chemical reactions occurring on the cellular level
Amino Acids the building blocks of proteins
Alpha Carbon central carbon atom of an amino acid, covalently bonded to the amino and carboxyl groups
Denaturation the process through which proteins lose their shape and function, often occurring due to an outside stimulant such as heat
Caseins hydrophobic protein found in milk that are vital to forming the curds used in cheese making
Whey by-product of cheese production that looks like a watery milk and is mainly composed of a group of water-soluble proteins, lactose, and minerals
Oxidation chemical reaction that adds oxygen to a compound
Coagulation type of permanent denaturation that results when a liquid or semiliquid protein forms solid or semisoft clots
Collagen protein in connective tissue that begins to soften and break down into gelatin when cooked in a moist heat
Millard Reaction reaction between proteins and carbohydrates that causes food to brown when cooked
Complete Proteins food that contains all the indispensable amino acids
Incomplete Proteins protein that is lacking one or more of the indispensable amino acids needed for human growth
Myoglobin iron-binding protein pigment in muscle tissue that provides color and holds oxygen in muscle tissue until it is needed
Reduction chemical reaction that removes oxygen from a compound
Gluten network of elastic protein strands that give bread dough its structure
Protein gel mixture of mostly fluids locked in a tangled three dimensional mesh made of denatured and coagulated proteins
Albumin protein found in egg whites and milk that act as a good foaming agent
Peptid Bond bond formed between two amino acids when an amine group combines with a carboxyl group and a water molecule is released
Polypeptide chain of multiple amino acids bound together by peptide bonds
Hydrophobic water repelling
Amine Group part of the amino acid acid structure that contains one nitrogen and two hydrogen atoms bonded to a carbon atom, represented by the symbol -NH2
