BIO: Macromolecules

what are the types of macromolecules

1. Carbohydrates

2. Lipids

3. Protein

4. Nucleic acids

What are carbohydrates

The body’s main source of energy

What are lipids

They store energy. Allows us to survive when carbohydrates are not being supplied to the body

What are Proteins

They form new bones and muscles and helps to fight if diseases

What are nucleic acids

The blueprint of our genetic structure. It stores and carries genetic information.

What are the 2 categories in carbohydrates

1. Sugars

2. Starch (complex carbohydrates)

Simplest carbohydrates

Monosaccharides which are monomers that complex carbohydrates are formed from

What are proteins made of

amino acids

When amino acid come together they form

Peptide bonds

When 2 peptide chains come together they form ?

Polypeptide

Lipids are categorized as

Fats and oils

They are technically not true polymers but are assembled from.

Triglycerides

( 3 fatty acids + Glycereral)

Nucleic acids are made from?

Nucleotides

Nucleotides are made of ?

1. A five-carbon sugar

2. A nitrogenous base ( adenine, thymine, cytosine, uracil, guanine)

3. A phosphoric acid called phosphate ( PO43-)
