Organic Compounds

 

I). Organic compounds

bullet

Contain carbon

bullet

covalently bonded

bullet

binds with hydrogen

bullet

units bind together

II). Monomers & Polymers

        Monomer is 1 subunit type of an organic compound.

        Polymer is a series of monomers.

or polycarbohydrates

(starch)

 

Lipids

 

Fatty acids

Saturated fats

Polyunsaturated fats

Amino Acids

Amino Acids

III). Carbohydrates

        A). Monosaccharide  

GLUCOSE:  C6H12O6

        B). Disaccharide

        C). Polysaccharide

 

IV). Lipids

            Insoluble in water but are soluble in other lipids.

        A). Neutral Fats

3 fatty acids + 1 glycerol  = triglyceride

Saturated fats: only single covalent bonds.

Polyunsaturated fats: double or triple bonds,.

       B). Phospholipids

The tail is nonpolar the head is polar.

        C). Steroids

 

V). Protein

                     Chains of amino acids linked by peptides bonds

        A).  amino acids.

 

B).  Fibrous and globular proteins

fibrous = structural proteins

globular  = functional proteins

                        

        C). Structure level of proteins:

                    i). Primary structure:  

                    ii). Secondary structure:  

                    iii). Tertiary structure

                    iv). Quaternary structure:  

Protein geometry

     

Proteins have a specific geometry

 

 

        D). Enzymes

Enzymes are globular proteins that act as biochemical catalysts.

They sometimes contain a non-protein part such as a metal (cofactor) or a vitamin (coenzyme)

lower the activation energy

Enzyme function

enzyme reactions

 i). The enzyme binds the substrate.

                         At a very specific active site

ii). The enzyme-substrate complex undergoes an internal change that forms the product

iii).  Releases the product;  free to attach to another substrate

 

VI). Nucleic Acids

 A). The 2 major classes include

Nucleotide Groups for DNA & RNA

DNA

RNA

Adenine

Adenine

Guanine

Guanine

Cytosine

Cytosine

Thymine

Uracil

B). Adenosine Triphosphate (ATP)

ATP is an t contains a high energy phosphate bond.

Chemical energy is stored in this high energy bond and released when the cell needs energy.
