Glucose
C6H12O6
Ribose
amino acids
There are 20 common amino acids found in the protein structures of living things. Amino acids are monomers which combine to form the larger polypeptides. In turn polypeptides combine to form proteins. Proteins molecules are the basis of enzymes and many cellular and extra cellular components.
fatty acids
basis of triglycerides
monosaccharides
glucose, frutose, galactose
disassharides
lactose, sucrose,maltose
polysaccharieds
cellulose, glycogen, starch
Functions of these in animals
Glucose
Lactose
Glycogen
glucose-respiratory substrate
lactose- milk sugar
glycogen-energy storage
Functions od thes in plants
Fructose
Sucrose
Cellulose
fructose- fruit sugar
sucrose-soluble, metabolically inactive, transported in phloem sap
cellulose-insoluble, structural fibres of plant cell wall
Outline the role of condensation and hydrolysis in the relationships between monosaccharides, disaccharides and polysaccharides; between fatty acids, glycerol and triglycerides; and between amino acids and polypeptides
Functions of Lipids
energy storage (adipose tissue)
thermal/electrical insolation ( adipose tissue, blubber)
beacouncy
forming membranes around our cells
LIPIDS ARE NON-POLAR
Carbohyrdates versus Lipids
Needed elements to be considered living
carbon, hydrogen, oxygen, nitrogen
(COHN)
other elements frequently found in living and functions
Iron - found in haemoglobin (animal)
Sodium-nerve impulse
Phosporus-found in cell membrane structure
Sulphur-important in amino acids
Calcium-bones and teeth
Water Molecule to show polarity plus hyrdogen bond
