Topic 1.2 Flashcards
Organic compounds
Key structure and function living things and they all contain carbon atoms
Carbohydrate
Are important in cells as they are reusable energy.
In pants,fungi and bacteria are an important parts of the cell wall.
Monosaccharide (simple sugars)
One oxygen atom and two hydrogen atoms
Triose sugars
3 carbon atoms
Pentose sugars
5 carbon atoms
Why are Ribosomes and dexyribosome important ?
They are important on the nucleic acid in the DNA and the RNA
Hexose sugars
6 carbon atoms
Disaccharide- double sugars
Two monosaccharide joined together. They result in a convalent bonds.
Monomer
Is a small molecule that is a single layer molecule
Polymer
A long chain many repeating units joined togeter by a chemical bond
Macromolecules
Is a large molecule often formed by polymerision
Starch is
A long chain of polymer is formed by glucose
Sucrose
A sweet tasting disaccharide
Glucose is a
Hexose sugar
Monosaccharides are
Simple sugars
Disaccharide
Made up of 2 monosaccharides units joined by a glycosic bonds
Polysaccharides
Made up of long chains by glycosic bonds
Deoxyribose
A Pentose sugars which makes up part of the DNA
DNA
Genetic material in many organisms
RNA
Nuclaic acid material in some organisms like protein synthesis
Isomers
Molecules rjat have the same chemical formula but different molecules structure
Condensation reaction
Is a molecule of water is removed from reaction as a bond is formed between them.
Glycosic bonds
Convalent bonds formed between two monosaccharides in a condensation reaction
Reacting sugars
React with Benedict’s solution
Non- reacting sugars
That don’t react with Benedict’s solution
Polysaccharide
Most complex carbohydrates, can form compact molecules and physically and chemically inactive and bit water soluble
Starch
Sugars are produced in photosynthesis which are changed into starch
Amylose
200-500 glucose molecules
Amylopectin
The molecule that can be broken
Glycogen
Referred as the animal starch as it’s the only starch in animals
Cellulose in plants
As the cell wall it’s strength and insoluble cellulose
Oilgosaccharides
3-10 monosaccharides units
Hydrolics
Reaction with a bonds are broken
Amylose
Complex carbohydrate containing glucose. So the molecule formed unbranched chain
Amylopectin
Is a complex carbohydrate containing glucose joined in both bonds
Cellulose
Complex carbohydrate with a 1-4 bonds
Lipids
Are another group of organic chemicals, many plants and animals convert from spare foods. Seeds of plants containing lipids
What is the difference between fat and oils?
Oils are liquid at room temperature
Nature of lipids
Play a key feature in warter proofing organisms like feathers and fur. It’s a good insulations, low density and dissolve in organic solvent but are insoluble in water
Phospholipids
Fatty chains are neutral and insoluble
Ester bonds
A bond is formed in a condensation round
Monounsaturated fatty acids
Only one double covalent bonds
Polyunsaturated fatty acids
Two or more convalent bonds
Hydrophobic
Molecules will not dissolve on water
Hydrophilic
Molecules that dissolve in water
Monolayer
Single closely packed atoms or molecules
Micelle
Spherical of molecules in water with hydrophobic areas in the middle and hydrophobic areas on the outside
Bilayer
Double layer of closely packed molecules or atoms
Unit membrane
Bilayer of structure formed by phospholipids with a hydrophobic tail and hydrophilic on the outside
Hydrogen bonds
Tiny negative charge are present in oxygen. Hydrogen atoms are weak
Disulfide bonds
Strong convalent bonds and are much stronger then hydrogen bonds and are important for holding chains in place
Primary Protein structure
A sequence of amino acids
Secondary protein structures
A chain held together by hydrogen bonds
Tertiary protein structure
Hydrogen bonds, disulfide bonds, ionic bonds between the amino acids
Quaternary protein structure
Only seen in certain proteins. Can be effective by temperature or the PH
Fibrous protein
Complex structure, large molecules, insoluble in water and tough
Collagen is
A fibrous protein that gives tendon and ligament bone to skin and is extremely strong and has a unusable structure
Conjugated protein
The shape very is important in the function
Glycoprotein
The carbohydrates parts of the molecule this helps then to hold warter
Amino acids are
The building blocks of protein
Peptide bonds
Bonds formed by condensation reaction between amino acids
Dipeptide
Two amino acid joined by a bond
Polypeptide
Is a long chain of amino acids
Fibrous protein
Proteins that have a long parallel chain with the occasional cross linkages
Disulifide bonds
A strong covalent bonds
Globular protein
Large proportion with complex tertiary and sometimes quanterany structures
Haemoglobin
Large conjoined protein involving the transport oxygen and gives blood it’s red colour
Denature
Protein with a double helix structure
Prosthetic group
Molecules which had in corporated in a conjunctive protein
Glycoprotein
Is a protein which a carbohydrate prosthetic group
Protease
Protein digesting enzymes
Lipoprotein
Is a protein with a lipid prosthetic group
