### protein:

Lipoprotein
* account for part of the nonspecific antiviral activity of human serum.
* are a combination of lipids covered by proteins
  - varying amounts of fats and proteins
  - actually aggregrates
  - carriers for transporting cholesterol throughout the body
  - compounds of fats and proteins
  - important in cell membranes and in transporting lipids in the blood
  - large molecules that transport fat and cholesterol in the body
  - larger and less dense, if they consist of more fat than of protein
  - macromolecular complexes of lipids and proteins, called apolipoproteins
  - most important when steroidogenic cells are chronically stimulated
  - outer monolayers of proteins and polar lipids with an inner core of neutral lipids
* are packages of fat, cholesterol, and protein
  - proteins, cholesterol and triglycerides assembled by the liver
  - particles that package cholesterol, allowing it to be transported in the blood
* are proteins carrying lipids
  - that carry lipids in the bloodstream
  - structures that transport cholesterol
* are the carriers of cholesterol and triglyceride
  - protein components that carry cholesterol through the circulation
  - vehicles that carry cholesterol through the blood stream
* carry triglyceride fats and cholesterol in the blood.
* come in different sizes
  - two types, and each affects our cardiovascular risk in different ways
* move cholesterol and triglycerides throughout the bloodstream.
* package water-insoluble lipids for transport through the bloodstream.
* particles that transport cholesterol to the liver.
* take their toll on the host.

Low protein
* Some low proteins are filtered by glomeruluses.
* diets impair immunity to infectious diseases.

Matrix protein
* Most matrix proteins play roles.
* Some matrix protein is shown travelling to the nucleus
  - travels to the nucleus and some collects beneath the cell membrane

Metabolizable protein
* accounts for rumen degradation of protein.
* is the total quantity of protein absorbed by the intestine
  - true protein absorbed by the intestine

Microbial protein
* Most microbial proteins play minor roles
* Some microbial proteins are generated by fermentation.
* has an excellent amino acid pattern.
* is an excellent source of protein with the correct amino acid profile
  - obtained through digestion of microorganisms

### protein:

Milk protein
* Many milk proteins have genetic variants which have been identified by letters of the alphabet.
* are also among the most common causes of food allergies
  - critical for milk foaming
* become insoluble.
* can cause a serious allergic reaction in susceptible persons.
* can cause an allergic reaction in susceptible people
  - colic, a digestive upset that bothers one in five infants
  - serious reactions in persons allergic to milk products
* common allergen, along with peanuts, citrus, wheat and corn.
* consists of several kinds of proteins and non- protein nitrogen compounds.
* entering the blood stream is perceived by the body as a foreign substance.
* has economic value because higher protein leads to higher cheese yields
  - two basic components, whey and casein
* have high levels of tryptophan.
* is affected by the amount and composition of the dietary protein
  - an excellent form of protein and is the one that most doctors prefer for infants
* tend to stay intact as milk is converted to dairy products of all types.

Mitochondrial protein
* Many mitochondrial proteins are part of a complex.
* are the targets of oxidative damage due to dopamine.
* vary depending on the tissue and the species.

Movement protein
* do many things in plant cells.
* interact with plasmodesmata to increase their size exclusion limit.
