Answer:

the building blocks of proteins

Question 8: Complete Proteins

Answer:

food that contains all the indispensable amino acids

Question 9: Denaturation

Answer:

the process through which proteins lose their shape and function, often occurring due to an outside stimulant such as heat

Answer:

chemical reaction that adds oxygen to a compound

Question 14: Enzymes

Answer:

chemical catalysts which promote and regulate almost all chemical reactions occurring on the cellular level

Question 15: Caseins

Answer:

hydrophobic protein found in milk that are vital to forming the curds used in cheese making

Question 16: Myoglobin

Answer:

iron-binding protein pigment in muscle tissue that provides color and holds oxygen in muscle tissue until it is needed

Answer:

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

Question 18: Whey

Answer:

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

Question 19: Peptid Bond

Answer:

bond formed between two amino acids when an amine group combines with a carboxyl group and a water molecule is released

Question 20: Contractile Proteins

Answer:

work closely with structural proteins; these allow for movement to occur and include actin and myosin

Answer:

reaction between proteins and carbohydrates that causes food to brown when cooked

Question 23: Albumin

Answer:

protein found in egg whites and milk that act as a good foaming agent

Question 24: Coagulation

Answer:

type of permanent denaturation that results when a liquid or semiliquid protein forms solid or semisoft clots

Question 25: Polypeptide

Answer:

chain of multiple amino acids bound together by peptide bonds

Question 26: Alpha Carbon

Answer:

central carbon atom of an amino acid, covalently bonded to the amino and carboxyl groups

Question 27: Transport Proteins

Answer:

help to move items within the body; include hemoglobin
