UNIT 2
Ammonia + carbon dioxide ammonium carbonate urea + water
Classifying carbon compounds:
1. Carbohydrates: consist of carbon, hydrogen and oxygen, hydrogen :
oxygen = 2:1
2. Lipids: insoluble in water, include steroids, waxes, fatty acids and
triglycerides (if at room temperature is solid, its a fat; if not, its a
lipid)
3. Proteins: one or more chains of amino acids. Contain carbon,
hydrogen, oxygen, and nitrogen (two out of twenty contain sulphur)
4. Nucleic acids: chains of subunits called nucleotides. Contain carbon,
hydrogen, oxygen, nitrogen, and phosphorus.
Identifying molecules:
- Proteins contain C, H, N, O whereas carbohydrates contain C, H, O but
not N
- Many proteins contain sulphur but carbohydrates and lipids no not
- Lipids contain relatively less oxygen than carbohydrates, ex: oleic acid
(an unsaturated fatty acid) is C
