|
Protein |
helps buld structures in the body and is involved in chemical reactions |
|
|
an important Subgroup of amino aids that are unique in muscle physiology
only one's that can be directly taken up by muscle tissue and oxidized for energy |
BCAAs |
|
|
amino acid role in metabolism |
aminoacids donate their Carbon skeleton to the TCA cycle The nitrogen group is changed into proteins in the body or used to form other nitrogen compounds |
|
|
nonessential amino acids |
can be removed from the diet and still be made from other amino acids |
|
|
nine essential amino acids |
phenylalanine Valine threonine tryptryptophan isoleucine methionine leucine lysine |
|
|
essential |
are normally Synthesized when adequate amounts Of precurSors are unavailable to meet the needs of the body |
|
|
glutamine |
nonessential amino acid that provides fuel for rapidly dividing Cells |
|
|
Most abundant protein in the body provides strength and structure to the body |
collagen |
|
|
amino acid as a fuel source |
aminoacids mustbe released from their protein structure from a body source or through digestion from the- foods |
|
|
protein function and classificatiOn |
Body proteins are broken down normally and provide bulding blocks Synthesize body proteins reason Why little protein is needed in our diet |
|
|
high quality protein Sources containing all the essential amino acids the body can't make on its Own are found in |
animal foods |
|
|
polypeptide bonds |
Long chains of amino acids joined by covalent bonds
when formed as a protein their complex characteristics work together to determine the specific function of that protein |
|
|
Protein function |
regulators by helping Pump molecules across cell membranes fluid regulators influence acid base balance transport oxygen, vitamins, and minerals for delivery to target cells throughout the body |
|
|
most abundant, protein that helps Maintain Structure of CT contributes elastic strength to bones and skin |
collagen |
|
|
substrates bind to the enzymes active site causing the active site to change shape resulting For Substrates to interact |
enzymes |
|
|
. protein denaturation |
Catabadie event responsible for destabilizing a protein's Shape the Shape uncoils into simpler chains and the surface area enlarges and digestive enzymes can now attack the peptide bonds |
|
|
proteuss chemical Messengers |
Interact with cells to signal Intracellular events |
|
|
proteins key role in Immunity |
defends against bacteria |
|
|
albumin |
large in size and attract water and remain inside the blood help balance fluid that i s lost through the Force of the heart pumping blood |
|
|
Proteins function in Maintaing PH in the body |
when acidity increases proteins pickup hydrogen ions blood is basic it donates hydrogen ions |
