Amino Acids, Proteins, Peptides

Question 1

Amino Acids

Answer 1

Building Blocks of Protein; Comprise of Amino Acid Group, Alpha Carbon, Carboxylic Acid Group and R Group

Question 2

Peptide Bond

Answer 2

Bond formed when two amino acids join (from C and N end)

Question 3

Peptide

Answer 3

Short string of Amino Acids

Question 4

Hydrolysis

Answer 4

Split of Peptide Bond by Water

Question 5

Properties of Peptides

Answer 5

Act as a Hormone, Antibiotic, & Prochlorisis (made from Cyanobacteria)

Question 6

Signficance of Resonance Structure of Peptide

Answer 6

Double Bond which means it cannot rotate

Question 7

What Molecule is Used during Hydrolysis?

Answer 7

H2O (water) is used to break a peptide bond.

Question 8

What are the functions of a Protein?

Answer 8

Cell Structure (Proteins are bound within cell membrane), Catalysts (Enzymes), Hormones (Insulin), Transport (Chemical across membrane), Antibodies (Combat Infections), Nutrients Storage

Question 9

What can we learn from Intact Proteins?

Answer 9

Organism, Where it was in Cell, What Function It Carried Out, Physiology

Question 10

What can we learn from Total Hydrolyzable & Free Amino Acids?

Answer 10

The Physiology and Freshness of Amino Acid

Question 11

Importance of Amino Acid

Answer 11

Huge Pool of Carbon in Global Carbon Cycle; Building Blocks of Protein

Question 12

Importance of Chiral Amino Acids

Answer 12

Amino Acids are mostly naturally Left Handed Form.

However, overtime L Amino Acids can mix to become equal amounts of L Amino Acids (Left) and D Amino Acids (Right)

This ratio can be used for Dating (ages, and search for life on other planets); Overall can be used for many years.
