Clues

  • A, G, C, T (4, 2, 3, 8, 2)
  • All have common structure (eg. sex hormones) - testosterone, oestrogen / estradiol, progesterone (7, 5, 8)
  • Androgens - testosterone = treatment of testes + breast cancer - promote tissue growth of muscles - synthetic forms used to help gain weight after debilitating diseases / Anabolic steroids = build up muscles + endurance in athletes (4, 7, 8)
  • Composed of carbon, hydrogen + oxygen (4, 3, 13)
  • Condensation reactions, releasing water, forming peptide bonds (3, 2, 5, 5, 4)
  • Fats + oils - esters made through condensation reactions between glycerol + 3 fatty acids (4, 3, 13)
  • Kashin-Beck disease = atrophy + degeneration of cartilage (8, 10)
  • linoleic acid / omega-6-fatty acid + linolenic acid / omega-3-fatty acid (9, 5, 5)
  • needed for healthy skin, good eyesight + protection against some damaging effects of toxins - orange / yellow fruits and vegetables, spinach + egg yolks - deficiency = xerophthalmia (dry eyes + night blindness) (7, 1, 10)
  • Water soluble - OH groups enable hydrogen bonds - cofactor in some enzymic reactions - important in tissue - helps give resistance to some diseases (7, 1, 8, 4)
