Macromolecules Flashcards
(37 cards)
fatty, water-insoluble (hydrophobic) molecules that function as stored energy, components of cellular membranes, and hormones
lipids
4 categories of lipids
Triglycerides (neutral fats), phospholipids, steroids, and eicosanoids
the only category of biological macromolecules that are not polymers
lipids
examples of steroids
cholesterol, steroid hormones, and bile salts
what is a triglyceride composed of
glycerol and 3 fatty acids (hydrocarbon chains)
what are phospholipids composed of
phosphate group, glycerol, an organic group, and 2 fatty acids
structure of eicosanoids
modified 20 carbon fatty acids
most common form of lipid in living things
triglyceride
used for long-term energy storage in adipose connective tissue, structural support, cushioning, and insulation
triglyceride
what is used to store triglycerides
adipose connective tissue
how many attached rings does a steroid have
4 (3 six carbon rings and 1 five carbon ring)
4 categories of eicosanoids
prostaglandin, prostacyclin, thromboxane, leukotriene
function of eicosanoids
primary function in the inflammatory response of the immune system and communications with the nervous system
fat-soluable vitamins
a and e
glycolipid structure
lipid molecules with an attached carbohydrate
function of glycolipids
cellular recognition to form tissues
number of carbon atoms in a carbohydrate
3-7
monomer of carbohydrates
monosaccharides
most common monosaccharide
glucose
primary nutrient in the body
glucose
the combining of glucose molecules together to form glycogen
glycogenesis
5 carbon monosaccharide examples
ribose and deoxyribose
biological macromolecules that store and transfer genetic information
nucleic acids
components of a nucleotide monomer
phosphate group, 5 carbon sugar (ribose or deoxyribose), and a nitrogenous base
