Lesson 3 P2: Amino Acid Flashcards
The building blocks of protein.
Amino Acid
A part of macromolecule containing an amino group NH2 and one carboxyl group COOH.
Amino Acid
How many natural amino acid occurring, and the amino acid that is present in feeds.
200 natural AA
20-25 AA present in feeds.
What are the three classification of amino acids?
Aliphatic, Aromatic, and Heterocyclic
An aliphatic amino acid that is a neutral.
Monoamino-monocarboxylic acid
An aliphatic amino acid that is acidic.
Monoamino-dicarboxylic acid
An aliphatic amino acid that is basic.
Diamino-monocarboxylic acid
What happens to the proteins when digested?
Broken down into amino acid.
What are the three classified amino acids that are based on animal needs?
EAA, NEAA, and LAA
A classification of amino acid based on animal needs that are needed by animal but unable to synthesize.
Essential Amino Acid
Other term for EAA
Indispensable or Dietary Essential
A classification of amino acid based on animal needs that are needed by animal and able to synthesize from other amino acid.
Non-essential amino acid
Other term of NEAA
dispensable or Dietary non-essential
A classification of amino acid based on animal needs that are present in protein but only in limited amount based on animal need.
Limiting amino acid
Example of LAA:
Lysine for growing pigs
Methionine and Cys for poultry diet
