Quiz 2: Chemical Level of Organization Flashcards
(CH2O)n
Carbohydrates
3-7 Carbon Atoms (glucose and fructose)
Monossacchrides
Two monosaccharides combines (sucrose and lactose)
Disaccharides
Two molecules with the same chemical formula but different shapes
Isomer
Three or more monosaccharides bound together
Polysaccharide
Structural element of cell wall of plants (humans can’t digest)
Cellulose
Long chains of glucose strung together (does not taste sweet)
Starch
Highly BRANCHED chains of glucose (animal starch)
Glycogen
Carbohydrates bound to proteins or lipids (glycoproteins/glycolids)
Conjugated Carbohydrates
Combine glucose and fructose to create…
Disaccharide - Sucrose
Tastes sweet/hydrophilic
Isomer
Hexagonal Monosaccharide
Glucose
Pentagonal Monosaccharide
Fructose
made/stored in liver, also stored in muscles, does not taste sweet
Glycogen
Fat molecules - hydrophobic
Lipids
composed of a long carbon chain with a carboxylic acid(-COOH) group at one end (hydrophilic)
Fatty acids
molecule composed entirely of single
bonds between adjacent carbons
Saturated Molecule
When you have one or moredouble bonds between adjacent carbons
Unsaturated Molecule
ONE double bond between adjacent carbon atoms
monounsaturated
TWO or more double bonds between adjacent carbon atoms
Polyunsaturated
Fatty acids attached to a glycerol molecule
Glycerides
Glycerol (alcohol) + three fatty acid groups (how your body stores fat/lipids)
Triglyceride
a diglyceride attached to a non-lipid group via a phosphate group
Phospholipids
Hydrophilic Head/Hydrophobic Tails
Phospholipids
a diglyceride attached to a carbohydrate; amphiphilic
Glycolipids
contain nitrogen, in addition to carbon, hydrogen, and oxygen
Proteins
Proteins - Composed of…
Composed of amino acids, linked by peptide bonds…
Essential amino acids - must have in diet
Non-essential - body can manufacture
Linear protein structure
Primary
Coil or Pleated protein structure
Secondary
Protein structure: ONE strand - ball of string or rope
Tertiary
Protein structure: MULTIPLE strands - ball of string or rope
Quaternary
Biological catalysts of the body
Enzymes
Combination of protein and carbohydrate molecules
Conjugated Proteins
DNA
Deoxyribonucleic Acid
RNA
Ribonucleic Acid
DNA and RNA
Nucleic Acid
sugar (ribose or deoxyribose) + phosphate group + nitrogenous base
Nucleotide
Basic unit of nucleic acid
Nucleotide
adenine, THYMINE, cytosine, guanine - DOUBLE strand (double helix)
DNA Bases
adenine, URACIL, cytosine, guanine - SINGLE strand
RNA Bases
Messenger from DNA to other parts of the body
RNA Bases
ATP
Adenosine triphosphate
The main high-energy compound off living systems
Adenosine triphosphate (ATP)
Used for in chemical bonds within the body/Constantly being used and replaced
ATP/ADP
Much larger molecules/Thousands of atoms
Carbon & Organic molecules
