Monomer
Small chemical unit that makes up a polymer.

POLYMER

CARBOHYDRATE

MONOSACCHARIDE

LIPID

NUCLEIC ACID

• Macromolecule containing hydrogen, nitrogen,carbon
• Phosphorus

NUCLEOTIDE

PROTEIN

• Macromolecule contains carbon,
• Hydrogen, oxygen, and nitrogen

AMINO ACID

• Compound with an amino group on one end
• Carboxyl group on the other end.

Untitled Slide

• Proteins are macromolecules that contains nitrogen as well as carbon, hydrogen and oxygen
• Animo acids are compounds With amoni group(–NH2) on one end and carboxyl group (–COOH) on the other end.
• More than 20 different amino acids are found in nature
• Amino acids are assembled into polypeptide chains according to instructions coded in DNA
• The protein hemoglobin consists of four subunits

CARBON CAN BOND WITH MANY ELEMENTS LIKE HYDROGEN,OXYGEN,PHOSPHORUS

• And Sulfur, and nitrogen to form the molecules of life
• One carbon atom can bond to another
• this gives carbon the ability to form chains that are almost unlimited length
• Carbon has ability to form millions of different large and complex structures
• No other elements even comes close to matching carbon's versatility.

Untitled Slide

• Biochemist sort thr molecules found in living things in to groups based on their chemical composition
• 4 major macromolecules found in living things are carbonhydrate, lipids, nucleic acids and proteins.
• Carbonhydrates are compounds made up of carbon, hydrogen, amd oxygen atoms.
• Glucose, supplies immediate enegy for cell activities.
• Organisms store extra sugar as complex carbonhydrates known as starches.

Untitled Slide

• Simple sugars molecules are also knows as monosaccharides.
• Plants use a slightly different polysaccharide( starch to store excess sugar)
• Plants also make cellulose.
• Cellubose is the major component of both wood and paper.
• Lipids wre made mostly from carbon and hydrogen atoms.

Untitled Slide

• Many organic compounds in living cells are so large that they are macromolecule
• Macromolecule means giant molecule.
• Macromolecules are formed by a process known as polymerization.
• The monomers join together to form polymers.
• The monomers and polymers may be idenical like the links on a metal watch band.

Untitled Slide

• A protein’s primary structure is the sequence of its amino acids
• Secondary structure is the folding or coiling of the polypeptide chain.
• three-dimensional arrangement of a polypeptide chain.
• protein found in red blood cells that helps to transport oxygen in bloodstram
• Some proteins control the rate of reactions and regulate cell processes.

Untitled Slide

• Buffers dissolved in lifes fluids play an important role in maintaining homeostasis in organisms
• Water molecules sometimes split apart to form ions.
• In pure water about 1 water molecule in 550 million splits to form ions in this way.
• The lower the pH, the greater the acidity.
• The higher the pH, the more basic the solution.
