Exosomes contain different cargoes; proteins, lipids, and nucleic acids. It synthesizes lipids, phospholipids, and steroids. Cell membranes contain a variety of biological molecules, notably lipids and proteins. The person receives nutritional formulas containing salts, glucose, amino acids, lipids and added vitamins. The liver also clears some proteins, lipids, and amino acids. Thiamine is required for metabolism including that of glucose, amino acids, and lipids. Acanthocytes arise from either alterations in membrane lipids or structural proteins. Lipase is a digestive enzyme that catalyses the hydrolysis of lipids (fats). K leads to crucial metabolic functions such as synthesis of lipids, proteins and glycogen. Hyperlipidemia is abnormally elevated levels of any or all lipids or lipoproteins in the blood. Neutral lipids and cholesterol are also present. Kinases act upon many other molecules besides proteins, lipids, and carbohydrates. Free radicals can damage proteins, lipids or DNA. They secrete matter that is particularly rich in carbohydrates, proteins and lipids. Such reactions include those that involve lipids, proteins, and carbohydrates.
