8.2 Protein Structure Flashcards
What are the basic building block of proteins?
Amino acids
Amino acids have an ________ group and a ________ ______ group in their chemical structure
amine, carboxalic acid
What is contained within an amine/amino group?
Nitrogen
When is contained within a carboxalic acid group?
Oxygen
What is the side chain?
The group of items attached in the bottom centre of the amino acid that differentiates it from the rest
How many amino acids are there?
21
What makes amino acids different?
What amino acids the side chain is composed of
__ amino acids are non-essential and __ are considered essential
12, 9
How can amino acids be used to make ATP?
The amino group (nitrogen containing group) must be taken off through deamination
The remaining structure can be used to go into the various steps of cellular respiration
What is a complete protein
A food with all 9 essential amino acids
What foods are complete proteins?
Animal products
What are limiting amino acids?
Essential amino acids missing from incomplete proteins
What is complementing proteins/mutual complementation?
Eating a variety of plant products so the amino acids complement each other
What is transamination?
The liver creating a non-essential amino acid during protein synthesis
