Chapter 4: Biological Molecules Flashcards
Carbohydrates
Substances that include sugars, starch and cellulose; they contain carbon, hydrogen, and oxygen
Sugars
Carbohydrates that have relatively small molecules. They are soluable in water and taste sweet.
Glucose
A sugar that is used in respiration to release energy
-made of six carbon atoms- 1 molecule(hexagonal shape)
glycogen
A carbohydrate that is used as an energy store in ani mal cells(larger molecules)
Starch
A carbohydrate that is used as an energy store in plant cells
Fats and oils
Lipids that are solid and liquid at room temperature. Made of Hydrogen, Oxygen, and Carbon atoms but have much less oxygen than carbohydrates.
Proteins
substance whose molecules are made of many different amino acids linked together. Their molecules contain four different atoms- Carbon, Hydrogen, Oxygen, Nitrogen(and sometimes sulfur)
