Hydrogenation Partially, fully o Fully: get rid of the double or triple bonds completely o Partially: get rid of some but not all of the double or triple bonds  o When food is hydrogenated, it becomes a solid (organic peanut  butter oil settles on the top, must mix it up; regular peanut butter is  hydrogenated so everything is creamy)  Trans-fats CW—Fats  Fats Cis vs. trans o Cis  hydrogens are on the same side  Preferred over the trans shape  o Trans  hydrogens are on the opposite side (behave like saturated fats)  Less trans fat helps your heart and lower cholesterol  When we eat fat (nonpolar), the body produces lipoproteins (combo of protein  and cholesterol; polarity on the inside, nonpolarity on the outside) to help move  the food around  Fat increases your blood cholesterol level  Steroids Lipoproteins o LDL Packets of phospholipids and fats that move and deliver it to the  bodies tissues (bad cholesterol) o HDL Sphere of (?) that moves cholesterol out of the liver (good  cholesterol) o Know (lipids provide… p 1001) o CW—Cholesterol and Lipoprotein Size Protein- amino acids Protein quality: o High (animal) vs. Low (plant)  High  getting all 19 of the amino acids Low  not all 19 are available; closest to having all the amino  acids is the soybean  Plant products do not have cholesterol only animal products do
