Nitrogen
Simplest element known, one proton one electron. 10th most abundant element in Earth’s crust
Hydrogen
4 biomolecules
Carbohydrates, proteins, lipid and nucleic acid
Greek “Sakcharon” means
Sugar
Also called saccharides. Diverse group of biomolecules that contain carbon, nitrogen and oxygen
Carbohydrates
Two types of carbohydrates
Simple carbohydrates and complex carbohydrates
Called simple sugar, sugar found in fruits, vegetable and milk
Simple carbohydrates
Also called starches, examples are whole grain bread, cereal, starchy vegetable. Contains fiber that helps in digestive health
Complex carbohydrates
3 classification of carbohydrates
Monosaccharide, disaccharide and polysaccharide
Are simple sugar. Derived for Greek single sugar. It is soluble in water
Monosaccharide
3 common monosaccharide
Galactose, fructose and glucose
Sugar found in milk and dairies
Galactose
Mostly found in vegetables and fruits
Fructose
Six carbon sugar carries in bloodstream. Also called blood sugar or dextrose
Glucose
It consists of two monosaccharide. Table sugar or sucrose
Diasscharides
Obtained from sugar cane and sugar beets
Sucrose
3 common diasscharides
Lactose, sucrose and maltose
Commonly know as milk sugar. Found in milk products
Lactose
Composed of glucose and fructose
