Examples |
Functional Group(s) |
Carbohydrate -ose (Marshall et al. 2014) |
CHO 1:2:1 |
– Short term energy storage for metabolism – Structure (cell walls & exoskeletons) -Makes food more favorable -Fat oxidation -Help cellular recognition process |
Monosaccharide |
-Glycogen -Chitin -Cellulose -Glucose fructose galactose -sucrose lactose maltose |
-OH |
Lipids (Nelson 2013) |
CHO 1:2:very few |
– Store large amount of energy – Structure (phospholipids are major component of cell membrane) -Source of vitamins A, D, E, K fat soluble ) -Protection of organs by generating heating -Act as chemical messenger |
Glycerol and fatty acids |
-Fats -Oils -Waxes -Cholesterol -Triglyceride (glycerol + 3 fatty acids) |
—CH2 —OH |
Proteins (Alberts et al. 2013) |
CHON No ratio (Amino and carboxyl groups present. Can be identified by the presence of peptide bond ) |
– long term energy storage – Provisional of structure support -Responding to stimuli -Storage and transportation of molecules -Body regulation- Formation of antibodies to strengthen immune system -Creation of hormone and Enzymatic activity –catalytic reactions -Synthesis and DNA and repair -Signal transduction |
Amino acids (Leucine, Alanine, isleucine, valine and others) |
Enzymes Structural protein |
—COOH (with long hydrocarbon chain- R-more than 16 C long) —NH2 |
Nucleic Acids (Rodwell et al. 2015) |
CHONP No ratio (Nucleotides are made of a five-carbon sugar, a nitrogenous base and a phosphate group) |
-Storage of genetic material -Transmission of genetic or hereditary information from one generation to next generation -Protein synthesis with the help of ribosome and RNA |
Nucleotides |
DNA RNA |
1 Nitrogen Base, 1 Phosphate, and 1 Sugar. |
