"Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown and storage of fats for energy and the synthesis of structural and functional lipids."
Study of the metabolic pathways involved in the breakdown and synthesis of lipids, including fatty acid oxidation, ketone body synthesis, and cholesterol synthesis.
Lipid structure: Understanding the chemical composition of different classes of lipids.
Lipid digestion: How lipids are broken down during digestion and absorbed into the body.
Lipid transport: How lipids are transported in the bloodstream, including cholesterol and triglycerides.
Lipid synthesis: How cells synthesize and modify different types of lipids.
Fatty acid metabolism: The breakdown and utilization of fatty acids for energy and storage.
Ketogenesis: The production and utilization of ketone bodies during periods of fasting or low carbohydrate intake.
Lipid signaling: The role of lipids as signaling molecules in the body, including eicosanoids.
Lipid storage disorders: Genetic disorders that affect lipid metabolism, such as Gaucher disease or Tay-Sachs disease.
Regulation of lipid metabolism: How lipid metabolism is regulated by hormones and other factors, including insulin and glucagon.
Lipotoxicity: The harmful effects of excess lipids on cells and tissues, including insulin resistance and inflammation.
Lipid digestion: The breakdown of complex lipids into smaller molecules that can be absorbed and utilized by the body.
Lipid transport: The movement of lipids within the body, including their transport in the bloodstream and delivery to cells for metabolism.
Lipid storage: The accumulation of lipids in specialized storage cells, such as adipocytes, for future use as an energy source.
Lipid mobilization: The release of stored lipids from adipocytes to provide energy during times of fasting or exercise.
Lipid synthesis: The process of creating new lipids, such as cholesterol and triglycerides, through a series of enzymatic reactions.
Lipid catabolism: The breakdown of lipids for energy production, which typically involves the removal of fatty acid chains from a glycerol backbone.
Lipid peroxidation: The oxidative modification of lipids, which can lead to cellular damage and contribute to disease.
Lipid signaling: The use of lipids as signaling molecules, such as the role of phospholipids in intracellular signaling pathways.
Lipid metabolism in disease: The role of lipid metabolism in a variety of diseases, including metabolic disorders, cardiovascular disease, and cancer.
Lipid metabolism in nutrition: The importance of lipid metabolism in human nutrition, including the role of dietary fat in health and disease prevention.
"In animals, these fats are obtained from food and are synthesized by the liver."
"Lipogenesis is the process of synthesizing these fats."
"The majority of lipids found in the human body from ingesting food are triglycerides and cholesterol."
"Since lipids are hydrophobic molecules, they need to be solubilized before their metabolism can begin."
"Lipid metabolism also occurs in plants, though the processes differ in some ways when compared to animals."
"The second step after hydrolysis is the absorption of the fatty acids into the epithelial cells of the intestinal wall."
"In the epithelial cells, fatty acids are packaged and transported to the rest of the body."
"Metabolic processes include lipid digestion, lipid absorption, lipid transportation, lipid storage, lipid catabolism, and lipid biosynthesis."
"Lipid catabolism is accomplished by a process known as beta oxidation which takes place in the mitochondria and peroxisome cell organelles."
"There are two sources of fats that organisms can use to obtain energy: from consumed dietary fats and from stored fat."
"Lipid catabolism is the breakdown and storage of fats for energy."
"The synthesis of structural and functional lipids is involved in the construction of cell membranes."
"Vertebrates (including humans) use both sources of fat to produce energy for organs such as the heart to function."
"Other types of lipids found in the body are fatty acids and membrane lipids."
"Lipid metabolism is often considered as the digestion and absorption process of dietary fat."
"Lipid metabolism often begins with hydrolysis, which occurs with the help of various enzymes in the digestive system."
"In the epithelial cells, fatty acids are packaged and transported to the rest of the body."
"Fatty acids are packaged and transported to the rest of the body."
"The process of synthesizing fats in the body is called lipogenesis."
