Primary Structures of Amino Acids

What are the 3 different types of proteins?

Fibrous (collagen)

Globular (Myoglobin)

Membrane (G-protein coupled receptor)

What are the functions of proteins?

Catalysis

Buffering

Storage

Transport

Motion

Structure

Defense

Regulation

Transducers

What are the essential Amino Acids?

Phenylalanine, tryptophan, histidine, leuscine, isolecusine, lysine, threonin, methionine, valine

What is the abrevation for telling if an Amino acid is charged?

DRCHEKS

DE negative, the rest are positive

Also CH and typically neutral

What is created from the decarboxylation of histidine?

Histamine

What creates Serotonin?

Tryptophan

What creates nitric oxide?

Arginine

What creates dopamine and epinephrine and DOPA

Tyrosine

What does a peptide bond eliminate?

It makes the molecule more stable and it has less ways to rotate, can onyl rotate around the Phi and Psi bonds

Also forces R groups to be trans of each other

Which bond is Phi?

C-N

Which bond is Psi?

C-C
