### protein:

Erythropoietin
* glycoprotein
  - hormone synthesized by the kidney in response to hypoxia
* hormone made in the kidney
  - produced by the kidneys that stimulates red blood cell production
  - released from the kidney and liver during periods of oxygen deficiency
* hormone that is made in and excreted from the kidney
  - triggers the body to produce red blood cells
* includes atoms.
* includes chemical chain
  - groups
* is an essential hormone for red blood cell production
  - both a mitogen and a survival factor
  - generally well tolaerated
  - often effective in treating chemotherapy-induced anemia and is well tolerated
  - produced by tubular cells of the rat kidney
* is produced in response to hypoxia by the interstitial fibroblasts of the kidney
* is produced in the kidney and liver in response to low oxygen levels
  - stimulates the production of red blood cells
  - naturally in the body
  - the hormone that regulates red blood cell production
* promotes the creation of red blood cells.
* protein responsible for the production of red blood cells.
* signals the bone marrow to make more oxygen-carrying red blood cells.
* stimulates Pluripotential stem cells to differentiate into RBCs.
* stimulates the bone marrow to produce red blood cells
* usually leads to an increase in hemoglobin and hematocrit within two to six weeks.
+ Blood, Red blood cells: Biochemistry :: Cardiovascular system
  * This is a protein. It is made to carry a large amount of oxygen. Haemoglobin has iron in it. The iron and oxygen gives haemoglobin its red color. This is why blood is red. Erythropoietin promotes the creation of red blood cells. Blood type antigens are carried on the surface of red cells.

### protein:

Excess protein
* Most excess proteins enter guts.
* can also cause overproduction of cecal pellets by overfeeding the cecal bacteria
  - lead to potential health risks, from kidney damage to osteoporosis
  - cause the urine to foam in water
  - contribute to ulcers and poor digestion
  - deprive the athlete of more efficient fuel and can lead to dehydration
  - leach calcium from the bones
  - put strain on the liver and kidneys
  - strain the kidneys, convert into fat, and promote calcium loss from the bones
* is an expensive and inefficient source of energy
  - broken down by the body and stored as fat, and the byproducts are excreted
  - metabolized to fat for energy storage just like excess carbohydrate
  - moved out of the limb, and fluid follows the protein molecules
  - primary cause of osteoporosis
* is stored as fat in the body
  - turned into fat or carbohydrate which is either used or stored
* is used as energy and can be stored as body fat
  - or stored as fat
  - utilised as an energy source
* leads to kidney overload and mineral deficiency diseases, such as osteoporosis.

Excessive protein
* Some excessive proteins cause damage
* can have effects
  - stimulate effects
  - irritate the immune system and keep it in a state of over-reactivity

Extra protein
* boosts pace of muscle cells on the move.
* can aggravate kidney failure and liver disease problems in older horses.
* is eliminated from the body or stored as fat
  - needed to supply energy without adding any more insulin to the body
