1)phospholipid

2)waxes

3)steroids

4)carotenoids

5)porphyrins

1) contain glycerol and 2 fatty acids, phosphate group, and nitrogen containing alcohol.

2) found in cell membranes, brain, nerves, and neural tissue

1) Made from esters of fatty acids, and monohydroxylic alcohols.

2)found as protective coating on skin, fur, leaves of higher plants, and on th exoskeleton of many insects. 

1) have three fused cyclohexane rings and one cyclopentane ring

2)they are found as cholesterol, sex hormones (testosterone and estrogen), and corticosteroids

1)fatty acid like carbon chains containing conjugated double bonds, with six member carbon ring at each end. 

2)compounds are pigments within which colors like red, yellow, orange and brown are made for plants and animals.

3) two sub groups are carotenes, and xanthophylis

1) contain four joined pyrrole rings, often complexed with metal like Fe in hemoglobin.

2) also called tetrapyrrole

Peptide

Dehydration

colloidal molecules clump together to form coacervated droplets (surrounded by shell of water). these droplets absorb the substance from the environment. the droplets have definite internal structure. These droplets were not living, but they did posses qualities of living organisms. 

They probably had nucleic polymer, and became capable of reproduction. 

production of usable energy without the use of free oxygen. 

Primitive heterotrophs developed complex biochemical pathways with led to this. The first developed anaerobic pathway was photosynthesis.

1) all living things are composed of cells

2)the cell is the basic functional unit of life.

3)cell arise only from pre-existing cells

4)cells carry genetic information in the form of DNA, which is passed from parent cell to daughter cell
