|
Carrier affinity |
Carriers take the largest amino acids first, then neutral, then the 10 essentials |
|
|
Where are the majority of proteins absorbed? |
The enterocyte |
|
|
First cell that can use amino acids? |
Enterocyte |
|
|
Enterocyte |
Prefers glutamine as energy/ATP source (amino acid). Uses proteins to make digestive (brush border) enzymes |
|
|
Basolateral membrane |
Last barrier to absorption. Transports amino acids using sodium from the enterocyte to the blood. Peptides cannot pass |
|
|
What is non protein nitrogen |
Ammonia, or nitrogen not connected to CHO. Urea is 100% DIP. Must add CHO when feeding for microbes to use |
|
|
DIP |
Degraded intake protein can be broken down and used by microbes to make microbial protein |
|
|
UIP |
Undegraded intake protein bypasses fermentation, goes to small intestine |
|
|
Protein Fractions |
Based on solubility in rumen (DIP) A is 100% DIP. instantly degraded B1, B2, B3 are potentially degraded C is undegradable |
|
|
Pancreatic lipase |
Act on triglyceride. Break bond between number 1 and 3 fatty acid, not two. |
|
|
Pancreatic colipase |
Activated by trypsin. Removes bile form triglyceride for recycling. Allow pancreatic lipase to break down fat. |
|
|
Transamination |
Recycling of excess amino acids |
|
|
Deamination |
Breakdown of protein for energy use |
