ZIMSEC O Level Biology Notes: Chemicals of Life: Carbohydrates

• In humans, mammals and a lot of other animals carbohydrates are the body’s main source of energy
• These may be simple, soluble sugars or complex materials like starch and cellulose
• But they all  are bio-molecules consisting of carbon (C), hydrogen (H) and oxygen (O)

ZIMSEC O Level Biology Notes: Chemicals of Life: Chemicals of Life: Test for Carbohydrates

• We have already looked at the structure, properties and use of carbohydrates here
• We will now examine the test for carbohydrates in food
• The nature and order of tests carried out depends on whether we are dealing with a reducing sugar or non-reducing […]
