Carbohydrates Leaving Cert Home Economics
- Monosaccharide – Carbohydrate with one sugar unit
- Disaccharide – Carbohydrate with two sugar units
- Polysaccharide – Carbohydrate with many sugar units
- Photosynthesis – How plants produce carbohydrates
- C6 H12 O6 – Chemical formula for a monosaccharide
- C12 H22 O11 – Chemical formula for a disaccharide
- (C6 H10 O5 ) n – Chemical formula for a polysaccharide
- 6CO2 + 6H2O + sunlight + Chlorophyll= C6 H12 O6 + 6O2 – Equation for photosynthesis
- carbon, hydrogen, oxygen – 3 elements found in carbohydrates
- glucose , fructose, galactose – 3 examples of monosaccharides
- sucrose, lactose, maltose – 3 examples of disaccharides
- starch, pectin, cellulose – 3 examples of polysaccharides
- heat & energy, spare proteins, energy reserve,insulator, helps movement of food – 5 biological functions of carbohydrates
- 25-35g – RDA of fibre
- NSP – non starch polysaccharide
- Digestion of carbohydrates – The breakdown of polysaccharides & disaccharides into monosaccharides.
- Hydrolysis – The adding of water to carbohydrates during digestion.
- Amylase – enzyme that works on starch breaking it down to maltose
- Maltase – enzyme that works on maltose breaking it down to glucose
- Lactase – enzyme that works on lactose breaking it down to glucose & galactose.
- Sucrase – enzyme that works on sucrose breaking it down to glucose & fructose.
- Gelatinisation – property of starch
- Soluble in water – property of sugar
- Helps jams to set – property of pectin
