pH
4 types of proteins
- Myosin
- Collagen
- Hemoglobin
- Albumin
Functions of proteins
- growth
2. tissue building
Main physiological role os proteins
-form neurotransmitters for brain and nerve function
Improves recovery for patients with sever infection or following surgery or trauma
Leucine
Leucine, isoleucine and valine
- positive effects in cancer patients with life threatening malnutrition
- contributes to white blood cell production
Arginine and methionine
-tissue regeneration for burn patients
state between protein synthesis (anabolism) and protein breakdown (catabolism)
Protein balance
4 types of proteins
- myosin
- collagen
- hemoglobin
- albumin
fibrous protein in muscle fiber
myosin
structural protein maintains form of bone, cartilage, skin etc.
collagen
Globular protein that binds and delivers oxygen to tissues
hemoglobin
Major plasma protein, carrier for drugs, hormones, enzymes and trace elements, and broken down in serious illness to supply amino acids
albumin
The building of body tissue
anabolism
The breaking down of body tissue
catabolism
A protein that contains all indispensable amino acids in the amounts needed according to the reference amino acid pattern.
complete protein
A protein with a lower amount of one or more of the indispensable amino acids as compared with the reference amino acid pattern or missing an indispensable amino acid needed to form body proteins.
incomplete protein
After trauma or surgery, ____ ____ are needed for wound healing and formation of new tissue, as well as the production of infection fighting immune factors.
amino acids
