1. A semi-solid viscous solution with a 3-D network where water molecules become trapped. Gelatine is used as a setting agent.






2. Chemical reaction when 2 amino acids join together with the elimination of water. Amino group of one amino acid combines with the carboxyl group of another amino acid.






3. Globular proteins linked with other non-protein molecules.






4. 230 - 250






5. A nutrient needed in large amounts (protein - carbohydrate - lipid)






6. Breaking down excess protein in the liver. Carboxyl group is converted to glycogen and stored as energy. Amino group is converted to ammonia then to urea and excreted as urine.

8. The 3 dimensional space to be designed






9. Bananas - orange juice - and tomatoes are great sources of this nutrient






10. 125g






11. A link formed during the condensation reaction when the amino group of one amino acid chemically combines with the carboxyl group of another amino acid with the loss of water molecule.






12. An enzyme made in the stomach which breaks protein into peptones.






13. Irreversible reaction - unfolding of the protein chain - caused by HEAT - ADDITION OF ACID & MECHANICAL ACTION.






14. Elements needed in small amounts for sturdy bones and teeth - healthy blood - and regular elimination of wastes






15. Meat - Fish - Chicken - Milk - Cheese - Eggs - Soya beans

28. Protein deficiency - causes dermatitis - retarded growth and a pot belly. Common is 3rd World.






29. Keeps the body healthy protecting it from diseases such as scurvy (Vit. C) and rickets (Vit. D).






30. Colour change which occurs when amino acids and sugar are exposed to dry heat. Also known as non-enzymic browning.






31. Provides heat and energy - satify hunger - provides padding around heart and kidneys.






32. Should be eaten sparingly






33. 125g






34. Cookie cutter house in master planned community - all have similar floor plans






35. 20g

39. Vitamin supplied by breads and grains






40. Works with calcium to build strong bones and teeth milk






41. Vegetables are a great source of this






42. Foods from the extras group are usually high






43. House built in rows and attached to one another at the side wall






44. Regulates body temperature - gets rid of waste via kidneys in urine - carries nutrients in blood.






45. Help the body build and repair and maintain tissues and body cells






46. Eggs belong in this food group






47. When 2 or more amino acids break apart due to the addition of a water molecule which splits the peptide link. This happen during digestion.
