_______________________ is the worst type of fat! They are man-made to promote
longer shelf-life of foods by making them solid instead of liquid. They lower the
amount of HDL and make your arteries rigid, causing them to clog more easily.

cholesterol and hormones.
-
_______________________ is involved in strengthening cellular membranes.
There are two types. High density lipoproteins are considered to be ___________
cholesterol and transport cholesterol from the body to the ______________ to be
broken down. Low density lipoproteins are considered to be _______________
cholesterol and transport cholesterol from the liver to the body.

but we must eat certain foods to obtain the other __________.
- Proteins are different from carbs and lipids because they contain the element
_________________ in them. They also sometimes contain __________________.
- Amino acids are linked together by what we call _______________ ______________.
- Proteins play a ______________________ role in our bodies. They make up hair,
collagen ( what makes our skin firm!), muscle, etc.
- Proteins that speed up chemical reactions are called _______________________.
They lower the ___________________ ___________________ in a chemical reaction.
