Polysaccharides

Biology 400a

If many monosaccharides are joined together through condensation, a polysaccharide is formed. Polysaccharides may consist of hundreds or even thousands of monosaccharide units Examples of polysaccharides: Importance and Functions of Polysaccharides Examples are: Makes the exoskeleton of arthropods, and walls…

Disaccharides

Biology 400a

These contain two monosaccharide units. The chemical process through which a large molecule (e.g a disaccharide) is formed from smaller molecules is called condensation and it involves loss of water Common examples of disaccharides include sucrose, maltose and lactose Sucrose…

Monosaccharides

Biology 400a

These are simple sugars. The carbon atoms in these sugars form a chain to which hydrogen and oxygen atoms are attached. Monosaccharides are classified according to the number of carbon atoms they possess The most common monosaccharides are: The general…

Photosynthesis: Process, Factors, And Meaning

Biology 400a

PROCESS OF PHOTOSYNTHESIS What is photosynthesis? Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. A general equation for photosynthesis…
