week 12 Flashcards
what are the different forms of carbohydrates
- Monosaccharides
- Disaccharide
- Polysaccharide
types of atoms carbohydrates are composed of
- carbon
- hydrogen
- oxygen
reaction to split polysaccharides
and what is required for this reaction to proceed
- needs enzymes
- Hydrolysis reaction
Polysaccharides
- Startch
- Glycogen
Disaccharides
- Sucrose
- Lactose
- Maltose
Monosaccharides
- Glucose
- Fructose
- Galactose
Pyranose
- 6 points
- Glucose + Galactose
Furanose
- 5 points
- Fructose
what is a fatty acid
- unbranded
- long chain
- C, O, R at the end
un saturated
- double bond
Saturated
- single bond
fatty acids soluble
- no
- because its hydrophobic
unsaturated fats in fish
omega 3
- reduces the plates from sticking together in the blood stream
omega 6
found in vegetable oil
triglycerides
- form fatty acids are stored in body cells
Glycerophospholipids
- cell membrane
- polar head
- hydrophobic tail
- important part cell permeability
Cephalins + lecithins
- brain tissue
- nerve tissue
Sphingomyelin
- myelin sheath
- lost in the disease MS
Structural
- provides structural components
- collagen, keratin
Contractile
- makes muscles move
- Myosin and Actin
Transport
- carry essential substances
- Hemoglobin and Lipoproteins
Storage
- Strore nutrients
- casein
Hormone
- Regulate body metabolism
- Insulin
Protection
- recognise and destroy foreign substances
- Immunglobulins
basic structure of amino acid
- contains a carboxylic acid group
- amino group on the alpha carbon
primary structure 1
- sequence of amino acids in a polypeptide chain
Secondary structure 2
- conformations of amino acids are localised regions of a polypeptide chain
Tertiary structure
- 3 dimensional arrangement of atoms in a polypeptide chain
quaternary structure
- spatial relationship
- interactions between subunits
