Role of Proteins Flashcards
one needed by the animal that cannot be synthesized by the animal in the amounts needed and so must be present in the protein of the feed as such
essential amino acid
one needed by the animals that can be formed from other amino acids by the animals and so does not have to be present as the particular amino acid in protein of the feed
Non-essential amino acid
Proteins are built up from amino acids means of a linkage between the a-carboxyl of one amino acid and the a -amino group of another acid.
primary structure
In this structure the peptide chain exist in the form of a right-handed -helix.
secondary structure
is the protein found in elastic tissues such as tendon and arteries rich in alanine and glycine
elastin
Are the protein of hair, hoof, nails etc. These proteins are very rich in sulphur
containing amino acid, cystiene
keratin
Are the main proteins of connective tissues. It make up about 30 percent of
the total proteins in the mammalian body.
collagen
This group includes all the enzymes, antigens and hormones that are protein.
globular protein
albumin, globulin, phosphoprotein, and protamines are all globular protein, except?
phosphoprotein
are basic protein of relatively low molecular weight, which are associated
with nucleic acid and are found in large quantities in the nature, germ cells of
vertebrates
protamine
Are basic protein, which occur in cell nucleus where they are associated with DNA. They are water-soluble but not heat coagulable, and on hydrolysis yield large quantities of histidine and lysine.
histones
present in eggs, milk and blood and are the main reserve protein source
in seed
globulin
water-soluble and heat coagulable and occurs in eggs, milk, blood and many plants
albumin
Phosphoprotein, Chromoproteins, Metalloproteins, Lipoproteins are example of?
conjugated proteins
PVT TIM HALL is the mnemonic for essential amino acids. Name all 10.
Phenylalanine
Valine
Threonine
Tryptophan
Isoleucine
Methionine
Histidine
Arginine
Leucine
Lysine
