Amino acids: types, structure and function

The video tutorial compares cake ingredients to protein structure, explaining how specific ingredients define a cake, similar to how amino acids define proteins. It covers the types of amino acids, their role as protein building blocks, and how they form polypeptide chains. The structure of amino acids, including the R group, is discussed, along with their behavioral categories: acidic, basic, polar, and nonpolar. The video concludes with how amino acids link via peptide bonds to form proteins.

What is the primary role of amino acids in the body?

• To regulate temperature

• To provide energy

• To build proteins

• To store fat

How are essential amino acids different from non-essential amino acids?

• Non-essential amino acids must be obtained from the diet

• Essential amino acids must be obtained from the diet

• Essential amino acids are produced by the body

• Non-essential amino acids are not used in protein synthesis

What determines the sequence of amino acids in a protein?

• The protein encoding genes

• The type of amino acids

• The amount of amino acids

• The temperature of the body

Which part of an amino acid determines its unique properties?

• The amino group

• The carboxyl group

• The R group

• The hydrogen atom

What type of bond links amino acids together in a protein?

• Ionic bond

• Hydrogen bond

• Peptide bond

• Covalent bond
