what are unsaturated fatty acids?
what is the degree of saturation of a fatty acid determined by?
sterols
triglycerides
omega-3-fatty acid
3 characterizations of fatty acids
basic functions of lipids in the body
what are many lipids comprised of?
kcals/gram for fat
omega-6-fatty acid
what are saturated fatty acids?
phospholipids
lipids
9 kcals/gram
double bond(s), liquid at room temperature, have a lower melting point
four connecting rings of carbon and hydrogen, do not contain glycerol or fatty acids, do not provide energy
category of compounds that include triglycerides, phospholipids, and sterols
stores and provides energy, provides insulation, helps manufacture steroids and bile, plays a role in transporting fat-soluble nutrients in the blood, used to manufacture major sex hormones, key to structure of cell membrane
a single or double bond
length of carbon chair, degree of saturation, and shape
glycerol backbone + two fatty acids + a phosphate group + nitrogen group, hydrophilic on one end & hydrophobic on the other
no double bonds, solid at room temperature, have higher melting point
first double bond is between 6th and 7th carbons from the omega end
glycerol + three fatty acids, add texture to baked goods, make meats tender, preserve freshness, store as adipose tissue for energy
first double bond is between 3rd and 4th carbons from omega end
chain of carbon and hydrogen atoms with a carboxyl group at the alpha end and a methyl group at the omega end
