脂肪組織
Lipids in the body are mainly contained in adipose tissue, which is made up of about 5-30% water, 2-3% protein, and 60-85% lipids, by weight, of which 90-99% are triglycerides. Adipose tissue is largely composed of neutral lipids, which collectively refers to triglycerides, diglyercides, phospholipids, and cholesterol esters, of which triglycerides are the most common. The fatty acid content of the triglycerides varies from person to person, but contains oleic acid in the greatest amount, followed by linoleic, palmitoleic, and palmitic acids.
