Proteins Composed of nitrogen,

carbon, oxygen, and hydrogen

Elements form Amino Acids 20 total Chains of A.A. form

proteins

Proteins- Amino Acids

Proteins Dipeptides

Two amino acids bonded together

Peptide bond Bonds two amino acids together

Polypeptides Long chains of amino acids

Proteins- Peptide Bonds

Proteins Shape of protein is

determined by the sequence of A.A.

Temperature and solvent can also influence shape

Proteins Enzymes

Highly specific One protein may have

only one function Catalyst in the body for

chemical reactions

Nucleic Acids 2 Forms of Nucleic Acids

DNA Deoxyribonucleic Acid

RNA Ribonucleic Acid

Messenger RNA (mRNA) Transfer RNA (tRNA) Ribosomal RNA (rRNA)
