Quiz 3 Flashcards
It is water soluble; present as albumen in egg white; in blood circulation, it performs various functions [e.g., as a carrier of lipids])
ALBUMIN
It is insoluble in water and are resistant to digestive enzymes
FIBROUS PROTEIN
A protein with sugar
GLYCOPROTEINS
Are organic compounds made up of different building blocks (basic units) called amino acids joined together by peptide bonds
PROTEINS
Is high in protein (keratin) but very low in digestibility and is of limited use in animal nutrition as a feed ingredient.
FEATHER MEAL
Are the building blocks of proteins
AMINO ACIDS
Amino acid that contain an asymmetric a-carbon (with four different chemical groups attached to it)
GLYCINE
Contain more carboxyl groups, and basic amino acids contain more amino groups
ACIDIC AMINO ACIDS
Contain an equal number of carboxyl and amino groups.
NEUTRAL AMINO ACIDS
Are those that cannot be synthesized by the animal body. There are 10 essential amino acids; cats need taurine, and chickens need glycine.
ESSENTIAL AMINO ACIDS
Is the process by which ingested feed is broken down physically and chemically to simple products for absorption from the digestive tract
DIGESTION
Soluble in dilute neutral solutions; functions as part of the immune system in body defense [e.g., immunoglobulins]
GLOBULIN
Proteins with heme units
HEMOPROTEIN
Proteins bound to nucleic acid
NUCLEOPROTEIN
Remove an amino acid from the end with a free carboxyl group, and aminopeptidase act on the terminal amino acid with a free amino group.
CARBOXYPEPTIDASES
Break peptide bonds within the primary structure into smaller fragments
ENDOPEPTIDASES
It is activated to form pepsin (active form) through HCl produced by parietal cells of the gastric mucosa.
PEPSINOGEN
Insoluble in water and are resistant to digestive enzymes 300 How many amino acids are known to exist in nature.
FIBROUS PROTEIN
It is commonly used as an amino acid supplement in animal feeds.
DL METHIONINE
It can be found in structural components of the body and are needed for many metabolic functions
PROTEINS
A long chain of amino acid formed by peptide bonds.
POLYPEPTIDE
Cleave amino acids off the terminal end of the protein molecule
EXOPEPTEDASIS
The presence of food in the stomach leads to the secretion of this substance by the chief cells of the gastric mucosa.
GASTRIN
Also secreted at the duodenum, converts trypsinogen into trypsin, which then converts chymotrypsinogen and procarboxypeptidase to their active forms-chymotrypsin and carboxypeptidase
ENTEROKINASE
Proteins that are not degraded by rumen microbes
ESCAPED/BYPASSED/ RUMEN UNDEGRADABLE PROTEINS
The major site of amino acid metabolism
LIVER
Is the removal of amino groups from amino acids to form ammonia
DEAMINATION
Contains the genetic code of the animal and is the blueprint of protein synthesis
DNA
Are synthesized through the process of transamination
NONESSENTIAL AMINO ACIDS
