Studying the liver in my college nutrition class. The information I am learning is so incredible I had to share! The most important part that struck home to me was that the liver treats alcohol the same as it does with any other poison… it protects the rest of our body by taking the damage! Please protect your liver folks… it is CRUCIAL to our survival! Not only does the liver do all of the following functions… it is also responsible for carrying all of our nutrients to our heart to be circulated throughout our body. My favorite part of this text is that it clearly states the liver “detoxifies” alcohol. Meaning alcohol is TOXIC. LET’S RENEW OUR APPRECIATION FOR THIS INCREDIBLY VITAL ORGAN!!

An enthusiastic anatomy and physiology professor once remarked that given the many vital activities of the liver, we should express our feelings to others by saying, “I love you with all my liver” instead of “with all my heart.” Granted, this declaration lacks romance, but it makes a valid point. Here are just some of the many jobs performed by the liver.
Metabolic Work of the Liver
CARBOHYDRATES:
- Metabolizes fructose, galactose, and glucose
- Makes and stores glycogen
- Breaks down glycogen and releases glucose
- Breaks down glucose for energy when needed
- Makes glucose from some amino acids and glycerol when needed
- Converts excess glucose and fructose to fatty acids
Lipids (fats):
- Builds and breaks down triglycerides, phospholipids, and cholesterol as needed
- Breaks down fatty acids for energy when needed
- Packages lipids in lipoproteins for transport to other body tissues
- Manufactures bile to send to the gallbladder for use in fat digestion
- Makes ketone bodies when necessary
Proteins:
- Manufactures nonessential amino acids that are in short supply
- Removes from circulation amino acids that are present in excess of need and converts them to other amino acids or deaminates them and converts them to glucose or fatty acids
- Removes ammonia from the blood and converts it to urea to be sent to the kidneys for excretion
- Makes other nitrogen-containing compounds the body needs (such as bases used in DNA and RNA)
- Makes many proteins
Other:
- Detoxifies alcohol, other drugs, and poisons; prepares waste products for excretion
- Helps dismantle old red blood cells and captures the iron for recycling
- Stores most vitamins and many minerals
- Activates vitamin D
