Biology - Macromolecules

Macromolecule

Organic compounds that contains carbon

Monomer

Smallest unit of a large molecule, created the loss of a water molecules (condensation or dehydration reactions)

Polymer

Large molecule consisting of 2+ monomers, dissasembles into monomers by hydrolysis (break with water)

What is the difference between hydrolysis and dehydration?

Dehydration creates monomers, hydrolysis breaks polymers into monomers

Condensation (dehydration reaction)

Reaction that creates monomers; 2 molecules are bonded through the loss of a water molecule

Hydrolysis

Process that breaks down monomers by the addition of water (Disaccharide + water = 2 monosaccharides)

Polymerization

The process of combining smaller molecules (monomers) to form the building blocks of life

What are the macromolecules

carbohydrates, lipids, proteins, nucleic acids

What are the 6 major elements important for life?

Carbon, oxygen, phosphorous, hydrogen, nitrogen, sulfur

Monosaccaride

carbohydrate made up of a single sugar unit, building block of larger carbs, (C6H12O6 = glucose, fructose and galactose)

Diasaccharide

Two monosaccharides join to form a double sugar. Ex: sucrose

Carbohydrate

compound made of carbon, hydrogen, and oxygen atoms; main source of energy, used for structure in plants, made up of sugars

What are the elements that make up carbs?

C, H, O

ATP

Common energy source in biology

Glucose

Monosaccharide made during photosynthesis, main source of energy for plants/animals

Fructose

Found in fruits, sweetest monosaccharide

Glactose

Found in milk (Milk sugar = glucose + glactose)

Lactose

Milk sugar, made of glucose and glactose

Sucrose

Disaccharide composed of glucose and fructose; table sugar

Glycogen

Polysaccharide used for storage; made of multiple glucose monomers

Cellulose

Polysaccharide used in plant structure

Polysaccharide

large macromolecule formed from 2+ monosaccharides; used for storage (starch - potatoes, glycogen) and building material (cellulose, chitin)

Lipid

Used to store energy for long term use, insulates and protects organs; is hydrophobic; composed of 1 glycerol + 3 fatty acids (C, H, O)

Saturated fat

A lipid made from fatty acids that have no double bonds between carbon atoms, primarily hydrogen; found in animals; solid at room temperature

Unsaturated fats

A lipid made from fatty acids that have carbon in double bonds; found in plants; liquid at room temperature

Protein

Polymer that allows the majority of processes in the body to take place; regulates reaction rates (enzymes), transports nutrients (hemoglobin), forms structure (collagen), and protects body (antibodies)

How many different Amino acids are there?

20 - the R group changes, and the amino/carboxyl groups stay the same

What are the three amino acid groups?

amino group, carboxyl group, R group

KNOW HOW TO DRAW AN AMINO ACID

Amino group = NH2, Carboxyl group = COOH, R group = HC + different atom per acid

Nucleic acid

Polymer containing hydrogen, oxygen, nitrogen, carbon, and phosphorus; stores/transport genetic info

DNA

Deoxyribonucleic acid; double helix

RNA

Ribonucliec acid; single helix

KNOW HOW TO DRAW A NUCLEOTIDE

Nitrogenous base (A, T, G, C, U), Pentose sugar (5 sugar, either ribose or deoxyribose), and phosphate group

Elements important to life

Carbon, phosphorus, nitrogen

Carbohydrate monomer

monosaccharide

Lipids monomer

fatty acids

nucleic acid monomer

nucleotide

Proteins monomer

amino acids

Common food source with starch

Potatoes

Carbs vs Lipids

Carbs are the main source of energy for all living things, plants also use this for structural purposes, made up of sugars Lipids are used to store energy for long term use. Insulate and product your bodies organs for example, fats, oils, waxes (make your cell membranes waterproof)

Elements found in proteins

CHON

DNA and RNA are examples of - acids

Nucleic

One thing that can affect the way enzymes work

Enzymes are examples of function of proteins. Enzymes are regulatory, so one thing they could be affected by is temperature changes/ reactions
